Lines & Wrinkles
Retinol is the #1 skin-transforming ingredient because it promotes the production of collagen and elastin — the building blocks for firm, plump, youthful-looking skin. Dr. Koo created 4 levels of retinol to be used at different ages and as your skin changes. Discover your level and experience the dramatic results.
LEVEL 2 – pH OPTIMUM RETINOL ACTIVATE - 2000 IUs
For mild to moderate wrinkles, uneven texture, and fine pores

LEVEL 3 – pH OPTIMUM RETINOL REPAIRING - 5000 IUs
For moderate to advanced wrinkles, irregular texture, and noticeable pores

LEVEL 4 – pH OPTIMUM RETINOL RESTORING - 8000 IUs
For deep wrinkles, rough texture, and significant pores

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.
