Cashmere

A prescription compounded serum that combines caffeine, GHK-Cu and tretinoin with niacinamide.

Firmer, more toned-looking skin, smoother texture, better elasticity, a brighter and more even tone, less crepey-looking skin, and a healthy skin barrier. It works through cell turnover, collagen support, barrier care and circulation.

Apply at night to the areas you're treating, once a day, or as your prescriber directs.

Mild redness, irritation, dryness or peeling can happen while your skin adjusts. Results build over weeks.

• Anyone pregnant or nursing, unless the prescriber says it's okay.
• Anyone with eczema or rosacea, unless the prescriber approves it.
• Don't layer it with other retinoids or exfoliants.
• Tell the prescriber about any ingredient allergies.
