What it does: The top layer of skin is destroyed via chemical, revealing a new one. Peels assist in removing brown spots and hyperpigmentation while minimizing injury to the outer layer of skin.
How it works: Acid (glycolic, lactic, alpha and beta hydroxy, typically) is applied to the face and, depending on its strength, can be left on for anywhere from a few minutes to overnight. Results are visible after about one week, and your skin may feel irritated or sensitive during that time.
Pain factor: Peels can sting and burn a bit, but about 15 minutes post-application one should feel fine.
Price: $300-$500 per series (depending on where you go and the strength and type of acid used)
Colleen's advice: “As we age, the desquamation process—meaning the skin's own ability to shed its outer layer of skin cells—slows down. A moderate to strong peel is especially great for women over 50. If done properly, your skin lines will soften, collagen will be stimulated, hydration levels will be boosted (once all has settled), your skin tone will be more even, and an overall glow should be noticeable." Colleen advises her clients to pair a peel with microdermabrasion for maximum effect.
