Introduction

Cosmetic and dermocosmetics have used the beta hydroxy acid salicylic acid (SA), to repair skin issues for ages, but this benefit came with major side effects such as dryness and irritation. SS Even Skin is a new technology offering a time release of SA, enabling the enjoyment of health benefits of SA without the typical side effects.

SA is a poorly-soluble ingredient and has consistently challenged formulation chemists because of its low solubility and its acidic effect on the pH of both formulas and the skin. SS ES is a revolutionary solution that allows for easy use of SA in aqueous, alcohol-free formulations. The encapsulated SA is designed to be compatible with commonly used, cost effective carbomer-based thickeners to produce clear products such as facial washes and lotions. This technology enables creation of new products in a single step, by adding the technology to the prepared base in an easy mixing process.

SS ES is loaded at 30% SA and can be diluted to any therapeutic concentration desired. In dermatology and dermocosmetics, the technology is best for the treatment of dermatitis, acne, psoriasis, calluses, dandruff, and more. In the cosmetic area, it is recommended for daily skin wash for toning, brightening, scar and pore reduction, excess sebum reduction, blemish removal, and skin smoothing for a younger and brighter look.

Evening Out of Skin

SS ES is designed to gently exfoliate the skin due to its adhesive nature. It provides a significant increase in long term exfoliation as compared to free (unencapsulated) salicylic acid from a wash application. In experimentation, it was found that SS ES provides a 20% increase of the exfoliation achieved by free salicylic acid. This difference is a significant one (n=21).

Percent difference of SS ES exfoliation as compared to free salicylic acid. Exfoliation is measured as dye reduction from human in-vivo tests.
