Celebrity-Loved Dermatologist Dhaval Bhanusali's Top 10 Skin-Care Products

Neutrogena Adapalene Gel Acne Treatment ($18, originally $40)

"For over-the-counter, the Neutrogena Adapalene 0.1% is a great option that can help yet still remains gentle," Dr. Bhanusali says. The prescription-strength formula is oil-free and fragrance-free, and it's best to use it at night.

However, acne isn't one-size-fits-all, and Dr. Bhanusali acknowledges the importance of identifying its cause and creating a custom treatment for each patient. "For more severe acne cases, I usually compound a topical with tretinoin, azelaic acid, and hyaluronic acid via Skin Medicinals."
