Doctor's Note

NOT ALL RETINOL IS CREATED EQUAL

If you experience irritation when you use retinol it may be because the retinol you’re using is not penetrating the skin, but rather sitting on the surface causing redness and discomfort. I made sure to encapsulate my retinol so it’s delivered deep into the skin matrix and absorbed into the skin cells where it enhances cellular function to improve collagen and elastin production with zero irritation.
