The hair follicle represents an important route whereby substances enter the skin. Your skin is designed to protect you from such chemicals invading your body. Given these findings, further investigation is needed to evaluate whether topical administration of ca­ffeine has a possible role in the prevention of skin cancer and how much it can inhibit sunlight-induced photo damage in humans. Systemic absorption of caffeine and its biotransformation to primary metabolites was extensively examined following percutaneous application to the dorsal skin of rats. Here are some of the purported benefits of caffeine for skin: Caffeine dilates the blood vessels under the skin, improving blood flow and reducing the appearance of cellulite. Caffeine holds certain properties that may benefit the skin. In 7 out of 9 laboratories, the maximum absorption rates of caffeine were ranked higher than testosterone.

In short, Goldenberg says, "Caffeine doesn’t cause acne. - Receptor fluid, receptor chamber, donor chamber (in vitro test system): The mean maximum absorption rate of caffeine through human skin membranes was 2.24 ± 1.43 µg/cm²/h, while the amount in the receptor fluid after 24 h was 24.5 ± 11.6% of the dose applied (9 laboratories). The ability of the skin to absorb caffeine as a topical agent is a subject of clinical investigation. Epub 2008 Feb 13. This may, in turn, also encourage faster delivery of topical substances. Given its potential to decrease the onset of skin cancer, decrease photo damage from UV exposure, and its role as an antioxidant, further investigations are needed to determine how e­ffective it may be in these particular roles as a cosmeceutical and a nutraceutical in both oral and topical form. Front Physiol. Caffeine is not the only substance known to interfere with iron absorption. Yet there is a lot of controversy surrounding its dosage and effectiveness. Cancer Res. In certain areas, hair follicles have “weak spots” that allow hydrophilic substances such as ca­ffeine to penetrate. al earlier this year to have a sunscreen effect, enhance UVB-induced apoptosis, and inhibit UVB-induced skin carcinogenesis when applied to the skin of mice. Recent advances in research on skin absorption of drugs and the effect of skin absorption enhancers, as investigated using confocal laser scanning microscopy, Raman confocal microscopy, and attenuated total reflectance Fourier-transform infrared spectroscopy, are reviewed. It is no surprise that many manufacturers have chosen to add small amounts of ca­ffeine to their topical formulations, cosmetics, skincare, and cosmeceutical products that are available on the market today. It may even play a role in promoting hair growth. The device used in this study will be a useful tool to investigate ex vivo, the influence of microclimate on percutaneous absorption. 3. Final report on the safety assessment of capsicum annuum extract, capsicum annuum fruit extract, capsicum annuum resin, capsicum annuum fruit powder, capsicum frutescens fruit, capsicum frutescens fruit extract, capsicum frutescens resin, and capsaicin. The variation observed may be largely attributed to human variability in dermal absorption and the skin source. Testosterone is the most lipophilic compound and showed also a higher presence in the skin membrane after 24 h than the two other compounds. However, with some calculations, the concentration of caffeine in cosmetic products and the limited penetration ability of caffeine (after 5 minutes) into the skin may not be significant enough to see immediate effects with one application. 2008 Mar;46 Suppl 1:S2-70.
