Clarification on Second Skin and Dimethicone Compatibility

You observed that some foundation products contain both Dimethicone and ingredients like Stearic Acid and Glyceryl Stearate, which are also listed as components of "Second Skin". This led to confusion because the description for "Second Skin" advises against using it with Dimethicone.

The key point, as clarified by the staff, is that "Second Skin" is a specific blend of multiple ingredients, not just Stearic Acid and Glyceryl Stearate. The full blend includes:

• Glyceryl Stearate
• Behenyl Alcohol
• Palmitic Acid
• Stearic Acid
• Lecithin
• Lauryl Alcohol
• Myristyl Alcohol
• Cetyl Alcohol

While the foundation products you saw contain individual ingredients like Stearic Acid and Glyceryl Stearate, they are not using the complete "Second Skin" blend.

Therefore, the reason those foundation formulas can contain Dimethicone alongside Stearic Acid and Glyceryl Stearate is that they are using these ingredients separately. The incompatibility mentioned in the "Second Skin" description refers to using the specific blend known as "Second Skin" together with Dimethicone.

In summary:

• Using the "Second Skin" blend (Product ID 1281) with Dimethicone (Product ID 508) is not recommended.
• Using individual ingredients like Stearic Acid and Glyceryl Stearate (Product ID 174) alongside Dimethicone is possible and common in cosmetic formulations.
