(PubMed), 26. After three months (forearms, N=16) or six to 12 months (face; N=8), histological abnormalities characteristic of end-stage epidermal photoaging (fewer cell layers, smaller cells, flattening of the dermatoepithelial junction, dense perinuclear clustering of large melanocytes, and hyperkeratosis) were corrected in tretinoin-treated skin. Kockaert M, Neumann M. Systemic and topical drugs for aging skin. (PubMed), 39. 2007;143(5):606-612. email: lpi@oregonstate.edu, Healthcare Professional Continuing Education. Tretinoin treatment resulted in an 80% increase in collagen I formation compared to baseline. Arch Dermatol. J Am Acad Dermatol. Punch biopsies (N=120) from forearm skin showed that isotretinoin increased epidermal thickness but did not alter any other histological parameters. Taking vitamin A supplements are said to treat acne by limiting sebum production on the skin. (PubMed), 22. 1980;269(3):297-309. Jick SS, Terris BZ, Jick H. First trimester topical tretinoin and congenital disorders. In this trial, 296 subjects (mean age, 42.5 years) applied topical tretinoin emollient cream (TEC) or vehicle to the entire face nightly for 24 weeks. 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. Oral isotretinoin (13-cis-retinoic acid) is used to treat severe cases of acne that are resistant to topical therapies (14, 53). A double-blind vehicle-controlled study. In vitamin A-replete rats, cod liver oil had no effect on the rate of wound healing. (PubMed), 27. JAMA. (PubMed), 11. J Am Acad Dermatol.

Topical tretinoin for treatment of photodamaged skin. (PubMed), 62. Vitamin A is one of the most widely acknowledged nutrients for healthy skin. J Exp Med. 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). There is also atrophy of many glands, including sweat and sebaceous glands (22, 23). It appears your device is already registered. In a randomized, double-blind, vehicle-controlled trial, 800 adults (mean age 53.5 years) with moderate to severe photodamage applied topical 0.1% isotretinoin (13-cis-retinoic acid) or vehicle to the face, forearms, and hands nightly for 36 weeks (45).

Cells in both the, A commonly experienced side effect following, Topical retinoids have a well-documented effect on skin health, with the majority of clinical evidence relating to their treatment of, Pretreatment with topical retinoids can mitigate some of the ultraviolet radiation (UVR)-induced changes that damage dermal. Histologic data showed that tretinoin-treated forearm skin exhibited increased epidermal thickness, compaction of the stratum corneum (SC), and increased vascularity in the papillary dermis compared to vehicle-treated skin. These trials provided abundant information regarding the effect of topical tretinoin on photodamaged skin, but they are somewhat limited by small sample sizes. Isotretinoin crosses the placenta and is teratogenic, meaning it causes developmental abnormalities. 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). The effect of topical retinoids on the leukotriene-B4-induced migration of polymorphonuclear leukocytes into human skin. (PubMed), 51. Computer image analysis revealed a 20% reduction in facial wrinkle length following isotretinoin treatment compared to baseline; no change was observed in vehicle-treated skin.

After discontinuation of oral therapy, isotretinoin disappears from both the skin and serum within two to four weeks (59). 13-cis retinoic acid exerts its specific activity on human sebocytes through selective intracellular isomerization to all-trans retinoic acid and binding to retinoid acid receptors. Oral isotretinoin reaches a steady-state concentration in plasma after one week of ingestion, yet there is no accumulation in the epidermis (59). Kligman AM, Grove GL, Hirose R, Leyden JJ. Director of the Photoaging and Aging Research Program 2000;114(3):480-486. J Invest Dermatol.

When the follicular wall surrounding a mature comedone ruptures, inflammatory acne lesions known as pustules and papules occur (54). A very common side effect of topical retinoid therapy is "retinoid dermatitis," also referred to as retinoid irritation or retinoid reaction. (PubMed), 52. Topical tretinoin (all-trans-retinoic acid, at-RA) is considered a very safe and effective treatment for mild to moderate acne (51, 52). Vitamin A Benefits 1. (PubMed), 30. This means it is able to influence cells to behave in a younger, healthier … Retinoic acid receptor-gamma in human epidermis preferentially traps all-trans retinoic acid as its ligand rather than 9-cis retinoic acid. Arch Dermatol. 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). This may take a few minutes as we confirm your details. 1992;26(2 Pt 1):215-224. Studies in animals demonstrate that vitamin A mitigates cortisone-induced defects in wound healing. 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. 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), 56. (PubMed), 13. Fisher GJ, Talwar HS, Xiao JH, et al. Although a much higher concentration of ROL was needed to achieve similar results (ROL was ~20-fold less potent than RA), ROL induced the same histological changes (hyperplasia and spongiosis) as at-RA without causing erythema. 1988;259(4):527-532. 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). 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). 1993;6 Suppl 1:8-16. J Invest Dermatol. A second very similar multicenter RCT compared these same doses of topical tretinoin in the treatment of photodamaged facial skin (17). 1987;17(2 Pt 1):251-254. Clinical improvements in fine wrinkling, roughness, and mottled hyperpigmentation were maintained or enhanced over the extension period. 1991;283(3):158-161. Strauss JS. Bhawan J. Short- and long-term histologic effects of topical tretinoin on photodamaged skin. Ann Surg. A multicenter, double-blind, vehicle-controlled trial assessed the efficacy of topical isotretinoin (13-cis-RA) in the treatment of mild to moderate facial acne (56). The primary pathophysiological factors leading to acne include increased sebum production, altered growth and differentiation of follicular keratinocytes, bacterial colonization of the follicle by P.acnes, and inflammatory and immune reactions (52, 54). J Invest Dermatol. 1991;127(5):659-665. Topical retinoids lead to visible improvement in fine wrinkling, smoothness, and hyperpigmentation of photodamaged skin (13-15, 25, 31). 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. Join our $20 for 20 years campaign to help sustain this free resource. Topical retinol improved clinical appearance (fine wrinkling) and increased the expression of two matrix molecules, glycosaminoglycan and procollagen I, compared to vehicle-treated skin.

Vitamin A’s ability to normalise how cells function. Naturally aged skin exhibits reduced fibroblast proliferation, increased MMP expression, and reduced collagen synthesis. (PubMed), 29. 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). Based on experimentation in animals, vitamin A deficiency is also associated with delayed wound repair (see Wound healing) (24). Incubation with radiolabelled β-carotene increased ROL concentration in cultures of human keratinocytes and melanocytes (11). More recently, 204 subjects (mean age, 63 years) with moderate to severe facial photodamage were randomized to apply 0.05% tretinoin emollient cream or vehicle once daily for two years (44). J Biol Chem. Typically, side effects associated with topical tretinoin are local skin reactions, such as redness, peeling, dryness, itching, and burning (14, 52). Keratinocytes and fibroblasts convert ROL first to retinaldehyde (RAL) and then to all-trans-retinoic acid (at-RA) (4). Amazingly, vitamin C's skin-saving benefits aren't limited to its antioxidant status. But there are also many unfounded myths about vitamin E for your skin, and it has not been proven that it can reduce scarring and stretch marks, or prevent skin … Dermatol Ther. 2003;2(4):435-441.

Oral isotretinoin is very effective in the treatment of severe cases of acne, however, safety issues are of major clinical importance (14, 53). But when combined with other essential nutrients (like antioxidants and peptides) known as Environ’s A+ Complex, that’s when you can begin to see and feel a healthier looking and more beautiful skin. It can be found in natural food sources such as carrots. Specifically, there is widespread keratinization, meaning that normal epithelium is replaced by stratified keratinizing epithelium, which has different functional properties (22). Exp Dermatol. It does so by normalising the activity of tyrosinase, an enzyme that plays a vital role in the production of melanin. 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. 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. In the skin, ROL is converted to retinaldehyde (RAL) and then to retinoic acid (RA). Cells in both the epidermis and dermis are targets for retinoid action.

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). Skin is a major retinoid-responsive tissue and vitamin A metabolites have been in use for decades for the treatment of various skin conditions, including acne vulgaris and photoaging. Vitamin A alone did not increase wound strength over control levels, yet vitamin A prevented the cortisone-induced reduction in wound strength. Dietary retinyl esters (RE) and β-carotene are converted to ROL by the liver. It appears your device is already registered. The physiological actions of retinoids in the skin are mediated primarily through their interactions with retinoic acid receptor (RAR) and retinoid X receptor (RXR), members of a superfamily of ligand-activated transcription factors (2). 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. Percutaneous absorption of topical tretinoin is minimal (see Topical application). Pathophysiology of premature skin aging induced by ultraviolet light. 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). Bryce GF, Bogdan NJ, Brown CC. 1993;329(8):530-535. Like vitamin C, vitamin E is an antioxidant. Nelson AM, Gilliland KL, Cong Z, Thiboutot DM. In vitro experiments indicate that isotretinoin also induces sebocyte death, further contributing to its sebosuppressive effect (9, 62).

Histologic evaluation of the long term effects of tretinoin on photodamaged skin. Tissue changes following deprivation of fat-soluble A vitamin. J Invest Dermatol. (PubMed), 19. 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). Using the beautiful science of this vitamin A+ complex, and understanding that vitamin A needed to be slowly reintroduced to skin to avoid retinoid reactions, Dr Des Fernandes created the worlds first Vitamin STEP-UP SYSTEM™. In a nutshell, Vitamin A in their various forms provide several significant benefits for skin: The 0.001% tretinoin was no more active than vehicle. Two hundred sixty-eight subjects (both genders, aged, 13-30 years) applied 0.05% isotretinoin gel or vehicle twice daily for 14 weeks. What’s more, vitamin A supports healthy skin cells, male and female reproduction and fetal development . Arch Dermatol Res. 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. Consistent with other reports, there was no change in plasma retinoid levels throughout the study period. It is the only known molecule that helps keep the skin healthy and helps to provide anti-aging benefits. 2005;6(4):245-253. Skin cells also have the capacity to convert β-carotene into vitamin A metabolites. 1993;341(8854):1181-1182. A small number of subjects [(N=27) from abovementioned trial (17) were followed even further, up to four years, after varying exposures of 0.001–0.05% TEC, applied once weekly to once daily (43). The term "retinoids" refers to vitamin A and the various molecules derived from vitamin A, which itself is also known as retinol (ROL). 1997;350(9085):1143-1144. 1986;15(4 Pt 2):836-859.
