The longevity of topical retinoid effects is uncertain and a long-term maintenance regimen is necessary in order to sustain retinoid-induced clinical improvements. (PubMed), 41. Thielitz A, Gollnick H. Topical retinoids in acne vulgaris: update on efficacy and safety. (PubMed), 3. (PubMed), 17. The information on dietary factors and supplements, food, and beverages contained on this website does not cover all possible uses, actions, precautions, side effects, and interactions. Supports Immunity. In a small sampling of adult subjects (N=6), biopsies of irradiated and non-irradiated buttock skin were compared before and after pretreatment with at-RA (26). In both groups, reversal of the increase in SC compaction, epidermal thickness, and number of granular cell layers was observed at the end of the extension period. Oral isotretinoin (13-cis-retinoic acid) is used to treat severe cases of acne that are resistant to topical therapies (14, 53). Oral isotretinoin is very effective in the treatment of severe cases of acne, however, safety issues are of major clinical importance (14, 53). This means it is able to influence cells to behave in a younger, healthier way, leaving skin looking youthful and more radiant. 0.01% tretinoin was less effective, only improving fine wrinkling scores. After inducing connective tissue damage by exposing hairless mice to UVR for 10 weeks, treatment with topical at-RA (0.05%) for 10 weeks significantly increased dermal vascularity and the size of the subepidermal repair zone (i.e., newly formed and organized collagen bundles) compared to untreated control mice (32). Wolbach SB, Howe PR. In the liver, ROL is either reesterified to RE for storage or released into the circulation (1). ROL has also been evaluated in the treatment of naturally aged human skin. 1997;350(9085):1143-1144. (PubMed), 54. In skin cells, other retinoids (9-cis-RA, 13-cis-RA, and at-ROL) isomerize to at-RA, the primary ligand that mediates RAR-dependent responses in human skin (7-10). Lancet. Consistent with these changes in human skin, studies in hairless mice demonstrate that topical at-RA induces a "zone of repair" in the subepidermal dermis in UV-damaged skin. (PubMed), 37. These trials provided abundant information regarding the effect of topical tretinoin on photodamaged skin, but they are somewhat limited by small sample sizes. Isotretinoin revisited: pluripotent effects on human sebaceous gland cells. J Invest Dermatol. Oral isotretinoin (13-cis-retinoic acid) therapy in severe acne: drug and vitamin A concentrations in serum and skin. The only way to counter this vitamin A deficiency is through the skin beneficial nutrition offered by vitamin A skincare products. Chalker DK, Lesher JL, Jr., Smith JG, Jr., et al. Both clinical and histological skin parameters return to baseline upon discontinuation of topical application of retinoids; thus, a long-term maintenance regimen is necessary to sustain retinoid-induced improvements (37). 1993;6 Suppl 1:8-16. 1996;379(6563):335-339. Vitamin A deficiency is uncommon in areas where healthy food is readily available.

These traits are reflective of histological changes in both the epidermis and dermis in sun-exposed skin. 2010;163(6):1157-1165. (PubMed), 6. In addition to their known role in the treatment of photodamaged skin (see Photoaging), pretreatment with retinoids might prevent ultraviolet (UV)-induced damage in the first place. Pfahl M. Signal transduction by retinoid receptors. (PubMed), 4. Some of the key benefits of this skin beneficial molecule include: When it comes to vitamin A skin care products, no skin care brand understands the importance and benefits of vitamin A better than Environ Skin Care. (PubMed), 27. While no changes were evident after six months, electron microscopy revealed clear morphological changes in the papillary dermis (replacement of disorganized collagen fibers with well-organized, packed fibers) after 12 months of topical 0.05% tretinoin treatment. Although use of topical retinoids is not associated with an increased incidence of birth defects in retrospective studies (57, 58), it is still advised to abstain from their use during pregnancy. Fisher GJ, Talwar HS, Xiao JH, et al. Mild cutaneous irritation was higher in the tretinoin group and peaked in the first two months, but the overall incidence of adverse events was similar in the tretinoin and placebo groups at the end of the study. Skin biopsies from 72 individuals from four age groups (18-29 years, 30-59 years, 60-79 years, and ≥80 years) were compared (46). Let’s take a look at the science behind the beauty and better understand the many positives that vitamin A brings to skin. Vehicle, at-ROL (1.6%), and at-RA (0.025%) were applied to different sites on the buttock skin of seven subjects and compared after four days of continuous occlusion. (PubMed), 20. (PubMed), 46. Topical application of other retinoids, such as isotretinoin and retinol also lead to clinical improvements, again with less skin irritation and after a much longer exposure time than tretinoin (19).

Vitamin A benefits are wide reaching and have an influential role in brain function, skin, heart, kidneys, lungs, vision, and immune system health. J Invest Dermatol. Cellular uptake of ROL from plasma is thought to occur via receptor-mediated uptake or endocytosis (1, 3). The mechanisms by which vitamin A counteracts cortisone-induced defects are not known, however, and further research in humans is necessary before the therapeutic application of vitamin A in wound healing can be realized. Chen S, Kiss I, Tramposch KM. Nelson AM, Gilliland KL, Cong Z, Thiboutot DM. Dermatol Ther. Notably, the UVR dose used in this study did not cause erythema and was equivalent to five to 15 minutes of exposure to noonday sun. A subset of subjects continued in an open-label format for a total of 10 months (N=21) or 22 months (N=16) of topical tretinoin treatment (40). This may take a few minutes as we confirm your details. Overall, long-term, continuous exposure to topical tretinoin results in significant improvement in clinical parameters, though histological changes vary over time (31). Orfanos CE, Zouboulis CC. J Am Acad Dermatol. The term "retinoids" refers to vitamin A and the various molecules derived from vitamin A, which itself is also known as retinol (ROL). (PubMed), 16. J Am Acad Dermatol. Kligman AM, Grove GL, Hirose R, Leyden JJ. Although the features of naturally aged and photodamaged skin differ, disrupted collagen homeostasis is thought to contribute to wrinkling in both situations (30). It encourages healthy skin cell production. It assists in the promotion of healthy collagen and elastin formation by stimulating fibroblasts (cells that produce collagen in the dermis), leaving skin looking firmer and more youthfully radiant. Clinical changes in fine wrinkling and texture of facial skin were sustained despite reduced dose (0.05%) or frequency (every other day) of tretinoin application. Pretreatment with at-RA inhibited UVB-induced AP-1 DNA-binding activity (a process call transrepression (27)), as well as MMP expression and activity by 50-80%. J Am Acad Dermatol. It helps in keeping … In a second human study, skin samples were obtained in irradiated and non-irradiated buttock skin from 59 white subjects (mean age, 35 years) who were pretreated with tretinoin or vehicle 48 hours prior to UV exposure (28). Ann Surg. Kafi R, Kwak HS, Schumacher WE, et al. (PubMed), 57. Oral isotretinoin reaches a steady-state concentration in plasma after one week of ingestion, yet there is no accumulation in the epidermis (59). Protects Eye Health. Topical retinol improved clinical appearance (fine wrinkling) and increased the expression of two matrix molecules, glycosaminoglycan and procollagen I, compared to vehicle-treated skin. Biological activity of all-trans retinol requires metabolic conversion to all-trans retinoic acid and is mediated through activation of nuclear retinoid receptors in human keratinocytes. Significant clinical improvement in mottled hyperpigmentation, fine wrinkling, and roughness, and the same histological changes noted above occurred with 0.05% and 0.01% TEC compared to vehicle, though 0.05% TEC was the most effective dose. (PubMed), 23. Singh M, Griffiths CE. 1941;114(4):791-798. Molecular basis of sun-induced premature skin ageing and retinoid antagonism. 1997;37(2 Pt 1):217-226. Thus, adjusting the timing, dose, and form of topical retinoid can influence the retinoid reaction. (PubMed), 45. Topical retinoids induce changes in the epidermis that lead to increased proliferation and altered differentiation of keratinocytes (see Photoaging); this in turn disrupts the barrier of the skin and contributes to the features of retinoid dermatitis (personal communication, Dr. Gary Fisher, December 2012). University of Michigan Department of Dermatology After 48 weeks of exposure, new histological changes were observed at both concentrations of TEC, including increased epidermal mucin content and reduced dermal elastin content. Topical at-RA also leads to stimulation of collagen synthesis and the effacement of UV-induced surface wrinkles in hairless mice (32-35). While it was not specifically determined that the vitamin A in cod liver oil was responsible for the accelerated healing in deficient animals, the authors demonstrated that linseed oil, rich in essential fatty acids, had no effect on the rate of wound healing in either scenario (48). Topical tretinoin influences the proliferation and differentiation of keratinocytes, thereby increasing follicular epithelial turnover, accelerated shedding of corneocytes, and the expulsion of mature comedones (52). Percutaneous absorption of topical tretinoin is minimal (see Topical application). Collagen I formation (detected immunohistochemically) was 56% lower in the papillary dermis in photodamaged skin. In one of the earliest evaluations of the efficacy of topical tretinoin on photodamaged skin, punch biopsies were obtained before and after treatment with 0.05% tretinoin cream or vehicle to photodamaged forearm and facial skin in a small sampling of elderly volunteers (aged 66-77 years) (38). J Am Acad Dermatol. There is approximately 5-fold more total RXR than total RAR protein. Olsen EA, Katz HI, Levine N, et al. One of the most well-known benefits of vitamin A is its ability to boost vision and keep your... 2. Treatment with lower tretinoin doses or other retinoid metabolites can achieve similar skin changes with less irritation but require a longer exposure time. Clin Interv Aging. When given in large to moderate doses within the first two to three days after injury, anti-inflammatory steroids reduce the rate of healing of surgical wounds (49). Weinstein GD, Nigra TP, Pochi PE, et al. When the follicular wall surrounding a mature comedone ruptures, inflammatory acne lesions known as pustules and papules occur (54). Isotretinoin crosses the placenta and is teratogenic, meaning it causes developmental abnormalities. Some of the key benefits of this skin beneficial molecule include: Vitamin A’s ability to normalise how cells function. More specifically, inflammatory lesion count was reduced by 55% with isotretinoin compared to 25% with vehicle; noninflammatory lesion count was reduced by 46% with isotretinoin compared to 14% with vehicle. Sandberg N. Time relationship between administration of cortisone and wound healing in rats. Nonetheless, due to the weight of evidence from studies in hairless mice and electron microscopic analysis of human skin samples, it is thought that clinical improvement to photodamaged skin is a consequence of increased collagen synthesis induced by at-RA. J Am Acad Dermatol. Topical tretinoin is considered a very safe and effective treatment for mild to moderate acne, while oral isotretinoin is used to treat severe cases of acne that are resistant to topical therapies; both therapies require physician oversight. J Invest Dermatol. Topical ROL increased dermal fibroblast number, reduced MMP expression, and increased collagen synthesis compared to vehicle-treated sites. The Linus Pauling Institute Micronutrient Information Center provides scientific information on the health aspects of dietary factors and supplements, food, and beverages for the general public. Excessive sebum production cause acne, which is stressing as it might take months to heal. After discontinuation of oral therapy, isotretinoin disappears from both the skin and serum within two to four weeks (59). Maddin S, Lauharanta J, Agache P, Burrows L, Zultak M, Bulger L. Isotretinoin improves the appearance of photodamaged skin: results of a 36-week, multicenter, double-blind, placebo-controlled trial.

Topically applied β-carotene increased the retinyl ester content in excised human skin samples in hairless mouse skin, demonstrating that β-carotene can serve as a precursor to epidermal vitamin A (12). Improves Vision. (PubMed), 59. Fisher GJ, Datta SC, Voorhees JJ. Like vitamin C, vitamin E is an antioxidant. Retinoids and the skin. Williams HC, Dellavalle RP, Garner S. Acne vulgaris. Feeding rats diets devoid of vitamin A affects epithelial tissues in various parts of the body, including the respiratory, alimentary, and genitourinary tracts, and the eyes and paraocular glands (22). Kurlandsky SB, Xiao JH, Duell EA, Voorhees JJ, Fisher GJ. 1997;36(6 Pt 2):S92-95. Most subjects reported mild cutaneous irritation on the ROL-treated arm, including erythema, peeling, pruritis, dryness, and burning/stinging. Topical retinoids lead to visible improvement in fine wrinkling, smoothness, and hyperpigmentation of photodamaged skin (13-15, 25, 31). (PubMed), 31. 2004;13(9):558-561. Its main function in skin care is to protect against sun damage. Retinol not only creates the pigments in the retina of the eye, according to NLM, but also is integral for good vision, especially night vision, and overall eye health. 1992;98(2):248-254. Kang S, Bergfeld W, Gottlieb AB, et al. All subjects received active treatment of either 0.05% TEC (N=126) or 0.01% TEC (N=133), although subjects and investigators were blinded to dose. We thank our supporters. Yamamoto O, Bhawan J, Solares G, Tsay AW, Gilchrest BA. As above, 0.05% tretinoin improved the same clinical and histological features of photoaging after six months of treatment. This means it is able to influence cells to behave in a younger, healthier … Please note that you will not receive your warranty if your email address is invalid.

In a separate study with the same study design, pretreatment with retinoic acid prevented UV-induced reductions in RXR-α and RAR-γ protein levels and transcriptional activity in buttock skin compared to non-irradiated sites on the same individual (N=70) (29). This system was designed to help skin become gradually more comfortable with increased levels of vitamin A and other ingredients that keep skin looking healthy and beautiful. Br J Dermatol. Vitamin A is widely considered one of the most important ingredients in skincare because it is the only molecule that can actually assist in reprogramming cells, resulting in healthier looking and more radiantly beautiful skin. (PubMed), 44. Typically, side effects associated with topical tretinoin are local skin reactions, such as redness, peeling, dryness, itching, and burning (14, 52). 1991;127(5):666-672. Skin Pharmacol. Specifically, there is widespread keratinization, meaning that normal epithelium is replaced by stratified keratinizing epithelium, which has different functional properties (22).

Vitamin A has many varied functions. It is not intended as nutritional or medical advice for individual problems. In a nutshell, Vitamin A in their various forms provide several significant benefits for skin: 1994;269(52):32821-32827. Exp Dermatol. The Benefits and Limits of Vitamin A for Your Skin Vitamin A and diet. Cells in both the epidermis and dermis are targets for retinoid action. A double-blind vehicle-controlled study. J Am Acad Dermatol. These observations set the stage for subsequent randomized controlled trials (RCTs) evaluating the safety and efficacy of topical retinoids in the treatment of photodamaged skin. With continued application, some early epidermal changes (SC compaction, increased epidermal and granular layer thickness) return to baseline while other histological changes (increased epidermal mucin content, increased dermal collagen synthesis) become evident. In a vehicle-controlled trial, the activity between all-trans-retinol (at-ROL) and all-trans-retinoic acid (at-RA) was compared in human skin (19). Different doses of topical tretinoin were evaluated in a large, multicenter, double-blind, vehicle-controlled RCT involving 533 subjects (mean age 42 years) with mild to moderately photodamaged facial skin (16). (PubMed), 21. RA modulates gene expression and influences cellular processes in both the epidermis and dermis, thereby exerting potent effects on skin health. of peanut oil supplemented with 1,500 IU vitamin A in the presence and absence of cortisone. (PubMed), 30. Your browser does not support the video tag. Arch Dermatol Res. Topical retinoids induce a number of histological changes in both the epidermis and dermis, and it is thought that changes in dermal collagen underlie the observed clinical improvements (32-36). Vitamin A also has antioxidant properties. A multicenter study. 1968;167(3):324-328. Vitamin A deficiency is associated with impaired immune function (see the article on Vitamin A) and delayed wound healing. As is the case in the treatment of visible signs of photoaging (see Photoaging), there is a need for a long-term maintenance regimen with topical retinoids in order to sustain remission of acne symptoms (52). Acne vulgaris affects the pilosebaceous unit, hair follicles in the skin that are associated with a sebaceous gland (54). A third multicenter RCT compared 0.05% or 0.01% topical tretinoin applied daily for 24 weeks to photodamaged facial skin in 299 subjects (mean age, 42 years) (18). (PubMed), 15. (PubMed), 22.
