In the present article, sunscreens containing the antioxidants vitamin E and diethylhexyl syringylidene malonate were tested for their efficacy in preventing UV-induced reactive oxygen species in the lower stratum corneum. The addition of the antioxidants was found to significantly improve the ability of low to high SPF sunscreens to attenuate ROS formation in UV-exposed skin.

Youthful skin is perceived as moist (or at least nondry), clean soft and virtually free of wrinkles. As consumers advance in age, concern about dry skin increases, and simply washing with soap and water gives way to us of products designed to treat the symptom, which all end up bearing some version of a moisturizer.

Skin discoloration and excessive pigmentation due to increased melanin production is associated with skin inflammation and aging. Therefore, an extract rich in acetylated hydroxystilbenes from Rheum rhaponticum was combined with panthenyl triacetate to test in the melanogenesis pathway. The complex strongly reduced melanogenesis and melanin accumulation in human skin explants, decreased melanin content in pigmented spots, increased skin brightness and enhanced skin radiance on the face of human volunteers in a double-blind clinical study.

Coffea species have been widely evaluated for effects including oxidative stress protection and immunomodulation. The present study therefore evaluates the cosmetic activity of an extract obtained from cultured Coffea bengalensis stem cells. Results showed the extract imparted hydration activity in the keratinocytes, stimulated collagen synthesis in the fibroblasts and enhanced adipocyte differentiation starting from mesenchymal precursor cells.

In this study, the effects of ultraviolet radiation (UVR) on trans-resveratrol were documented, finding that UV radiation causes it to undergo rapid and extensive photoisomerization and some photodecomposition. The antioxidant activity of trans-resveratrol is correspondingly reduced. However, in the presence of ethylhexyl methoxycrylene, a photostabilizer used in sunscreens, the effects of UV exposure on trans-resveratrol are minimized, thereby preserving its antioxidant activity and, presumably, its bioavailability.

L-Ascorbic acid (AscA), more commonly referred to as vitamin C, is best known for its vital role in human health and nutrition, where it functions as a cofactor in enzymatic reactions, such as collagen synthesis, and as an antioxidant.

The term “skin lightening” has been positioned in the cosmetic market to denote the return of skin’s color to a more natural transparent tone, providing a more even skin tone and lighter skin pigment. Topical skin lighteners suppress production of melanin pigment, prevent darkening of the skin or modify pigmentation such as blotches and freckles.

The quest for PEG-free surfactants and emulsifiers has led to new classes of vegetal-derived, ethylene oxidefree ingredients for environmentally friendly personal care products. Two such ingredients, described here, are based on the combination of olive oil and vegetable proteins with the first derived from oat and the second, with glutamic acid. These materials provide mildness and skin protection benefits.
