Summer is over: it is the perfect time to start up your chemical peel regimen. While this may sound counterintuitive for some, it actually makes great sense. Here is what you need to know.

What Is a Chemical Peel?

Very simply, when you get a chemical peel, you are having a chemical solution applied to your skin, removing a few top layers. While it sounds ominous, the chemical peel actually takes advantage of the natural cell regeneration process our bodies undergo on their own. The new skin usually grows in looking smoother, less wrinkly, and more even in color.

That's why chemical peels are often used to treat scars, lines, discolorations, and other conditions. 

Different Ingredients in Chemical Peels

Chemical peels are available in different strengths and are comprised of different ingredients, the most common being:

• Glycolic acid is an alpha hydroxy acid (AHA) derived from fruit. Since it has a small molecular structure, it can penetrate deep into the skin to dissolve dead skin cells and sebum and isn't abrasive. Glycolic acid peels tend to give a healthy glow to the skin and leave it younger-looking and smoother.

• Salicylic acid is an ingredient you see a lot in acne treatments. It is a beta-hydroxy acid (BHA) derived from willow bark and used to control oil, exfoliate, and reduce inflammation in the skin. Salicylic acid peels are great if you suffer from breakouts or clogged pores.

• Lactic acid is an AHA found in many milk products and is usually derived from sugars. Lactic acid exfoliates and breaks up dead skin cells on the outer layers of the skin, allowing for the generation of new skin. Lactic acid is said to boost moisture in the skin so it feels more hydrated and plumper, and it is often used by those with sensitive skin.

• Sometimes called a "Hollywood-style peel" by beauticians, phytic acid peels can be done throughout the year, as it is a superficial peel that doesn't require much recovery. Not only does phytic acid exfoliate and cleanse the skin, but it also inactivates tyrosinase, an enzyme that causes hyperpigmentation when produced in excess.

• Derived from denatured vitamin A, also known as retinoids, retinoic acid stimulates skin cell division and seals in moisture in the deepest levels of the skin. It also stimulates the production of collagen and works as an antiseptic. Retinoic acid is effective at rejuvenating skin and reducing lines and wrinkles.

• Also known as TCA, trichloroacetic acid is used to exfoliate and renew skin cell. It works well as a spot treatment and penetrates deeply into the skin, improving fine lines, scars, hyperpigmentation, as well as the production of collagen and elastin. TCA peels come in different strengths.

• Carbolic acid is the main active ingredient in phenol peels, which are the deepest, strongest chemical peels available. The results can be dramatic — treating sun damage, wrinkles, scars, and even some pre-cancerous growths. Skin texture, tone, and pigmentation are also improved. You should check with your aesthetician to see if a carbolic acid peel may be too strong for your skin.

Why Chemical Peels Are Great in the Fall and Winter

Skin tends to be more sensitive to sunlight after a chemical peel, and the sun is not as glaring during the fall and winter months. Additionally, doing a chemical peel in the colder months will prepare your skin for the warmer months. Your aesthetician can recommend the best for your skin type and condition.
