Skin lightening peels are a type of chemical peel treatment designed to even out skin tone by reducing hyperpigmentation. They work by exfoliating the outer layers of the skin, allowing new, evenly pigmented skin to emerge. Commonly used peels include alpha hydroxy acids (such as glycolic and lactic acids), beta hydroxy acid (salicylic acid), and trichloroacetic acid (TCA). These treatments improve skin texture and radiance and are effective for reducing dark spots, melasma, and other pigmentation issues.
Glycolic Acid (GA): Also known as a fruit peel, GA peels are inexpensive with no downtime. Typically used in 30-70% concentrations, these peels have anti-inflammatory and antioxidant effects. Sessions are recommended every 2-3 weeks for a total of 4-6 treatments.
Lactic Acid (LA): Derived from milk, lactic acid peels reduce cell cohesion and work well for lightening dark spots, often used at 92% strength. Applied every 3 weeks for best results.
Salicylic Acid (SA): This beta hydroxy acid is useful for exfoliating the top layer of skin, reducing pigmentation and inflammation. Salicylic acid peels are used in 20-30% concentrations to lighten superficial skin pigment.
Trichloroacetic Acid (TCA): A vinegar-derived acid, TCA peels offer deeper penetration for more substantial results. Used at 15% for superficial effects, these peels are conducted monthly, usually in a series of four treatments.
Here are some common questions about skin lightening peels, their benefits, and how to care for your skin post-treatment.
Skin lightening peels involve applying a chemical solution to exfoliate the top layers of skin, reducing dark spots and evening out skin tone.
The skin is cleansed and toned before applying the peel, which is left on for 3-5 minutes. Mild tingling or burning may occur. Afterward, a cool compress is applied, and the skin is moisturized with an antioxidant and sunscreen.
Apply sunscreen daily, avoid picking at the skin, and keep it moisturized. Use a broad-spectrum sunscreen of SPF 30 or higher to prevent discoloration.
Healing time is about 7-14 days, with some redness potentially lasting for months after a medium peel.
Results vary depending on peel strength, lasting from one month for light peels to several months for medium to deep peels.
Common side effects include redness, scabbing, and swelling. More severe side effects can include scarring, infection, and pigmentation changes.
Those with darker skin tones should be cautious, as peels may cause pigmentation changes in newly healed skin.
Light peels can be done monthly, while medium to deep peels should have intervals of four to six months or longer.
