Chemical Peels

Chemical peels are not all alike, but each works toward to the same thing – removing damage on the outer layer of one’s skin. Three main types of peels are described by the American Society of Plastic Surgeons: alphahydroxy acid (AHA) peels (least abrasive), trichloroacetic acid  (TCA) peels (for medium peels), and phenol peels (most aggressive).

While an AHA peel has more subtle effects on diminishing the appearance of fine lines, its gentleness means it may be suitable for use when patients can’t take time to recuperate – and it may be recruited for a multi-part treatment (for example, multiple sessions over time or a single treatment used in conjunction with AHA cleansers or moisturizers).

Going to the next level, TCA peels vary in strength but are often used when a stronger result is desired than AHAs will provide. They do not, however, provide the same benefits or require the healing time of a phenol peel.

Phenol peels may actually provide a ‘deep’ peel – improving coarse wrinkles, removing pre-cancerous skin, and minimizing cases where skin has gotten blotchy from uneven sun exposure. Typically, phenols are used only on the face; there are greater risks of scarring if it is applied on the neck or elsewhere. With this powerful peel comes more risks; such a strong treatment may negate your skin’s ability to tan (and necessitate more sun protection) and may pose a special risk for those with heart disease.

Just as risks grow with the strength of the peel type, so do periods for healing and seeing results: AHAs have more subtle effects, whereas phenols may offer substantial visual changes and may enhance the appearance for a longer term.

Chemical peels take advantage of science, and the serious results (though some are less long-term than others) require serious attention to care.
