How Tretinoin Works

Tretinoin works by promoting the turnover of skin cells, which helps clear up acne and improve the skin’s appearance. It encourages the shedding of old skin cells and the growth of new ones.

This process helps unclog pores and reduces the formation of acne lesions.

As a retinoid, it can also help reduce fine lines and pigmentation by stimulating collagen production.
