Advanced Retinol Sandwich Package Sale

Retinol Sandwich is a skin care industry term for a layering strategy, including using a retinol concentrate combined with retinol cream. This method aims to prevent irritation caused by retinol products, which can be highly potent and drying for certain skin types. The premise behind the Retinol Sandwich is that the moisturizer creates a “barrier” between the retinol and the skin, limiting the amount of retinol that comes into direct contact with the skin and minimizing irritation. This method is beneficial for individuals with sensitive skin or those who are new to using retinol products.
