SalSphere® Even Skin

PID# 8894

A time release delivery system for salicylic acid (SA) and natural exfoliating enzymes for gentle exfoliation and skin rejuvenation

  • Evens and smooths the skin through chemical exfoliation tailored for sensitive skin.
  • Promotes healthy, glowing skin and diminishes skin imperfections.
  • Suitable as anti-acne and anti-blemish in washes, serums and lotions.


SS ES is a unique technology that combines the benefits of salicylic acid (SA) with the exfoliating properties of bromelain and papain enzymes.

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.

The bromelain and papain enzymes dissolve dead skin cells that can potentially clog your skin pores. These natural ingredients gently, but effectively remove the outer layer of dead skin cells and leave your face feeling smooth and fresh. Papaya achieves enzymatic exfoliation, rather than harsh mechanical exfoliation with grainy creams or a brush.

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.

Formulation Guidelines

SS ES can be added at any stage of the formulation process at temperature below 40°C. For formulas using carbomers as thickeners, SS ES must be added before the neutralization of the carbomer. Suggested carbomer concentrations are from 0.5-1.5% W/W to provide a serum to a gel structure respectively. pH of final formula has to be minimum of 4.5.
