ALTRENO (tretinoin)

Dermatology Approved 2018-08-23

Altreno is a topical retinoid lotion used for acne vulgaris in patients 9 years of age and older. This medication helps patients with skin breakouts by targeting the underlying cellular processes that cause acne to form. As a vitamin A derivative, it helps clear existing lesions and prevents the development of new ones.

How ALTRENO Works

This drug works by binding to specific retinoic acid receptors to modify gene expression and epithelial cell growth. It helps clear acne by decreasing the stickiness of skin cells to prevent new clogs from forming. Additionally, it increases cell turnover, which helps the skin shed existing comedones.
