A chemical peel is a dermatological treatment that applies controlled-concentration acid solutions to the skin to remove damaged superficial layers and stimulate the natural process of cellular regeneration. Through controlled exfoliation, the skin renews itself deeply, becoming more radiant, firm, and even-toned. It is one of the most versatile treatments in aesthetic medicine, successfully used for decades to improve skin quality and address numerous imperfections.
There are different types of peels based on depth of action and type of acid used: • Superficial peel (glycolic, mandelic, salicylic acid): acts on the stratum corneum, ideal for light spots, dull skin, and enlarged pores. Requires no significant recovery time • Medium peel (trichloroacetic acid TCA): penetrates to the papillary dermis, effective for fine wrinkles, superficial scars, and more pronounced discoloration. Requires 5-7 days of recovery with peeling • Deep peel (phenol): reaches the reticular dermis, indicated for deep wrinkles, significant scars, and severe photodamage. Requires a longer recovery of 10-14 days
• Skin spots and discoloration, including sun spots and melasma, to even out the complexion • Fine wrinkles and expression lines on the face, for a rejuvenating and smoothing effect • Superficial and moderate acne scars, to smooth and improve skin texture • Dull, lackluster skin with a tired appearance, to restore radiance and vitality • Enlarged pores and comedones, to refine skin texture and reduce imperfections
• Active or recurrent herpes in the treatment area, to avoid virus reactivation during the healing phase. For recurrent herpes, preventive antiviral prophylaxis is possible • Isotretinoin use within the previous 6-12 months, as the medication alters the skin's regenerative capacity, increasing the risk of abnormal scarring • Recent sun exposure or tan, which increases the risk of post-inflammatory hyperpigmentation • Pregnancy and breastfeeding, as a precautionary principle • Open wounds, active dermatitis, or eczema in the treatment area
The treatment takes 20-45 minutes depending on the type of peel and the extent of the area being treated. Recovery varies significantly based on depth: superficial peels require just 1-3 days with mild flaking, medium peels 5-7 days with more noticeable peeling, while deep peels require 10-14 days with redness and more intense skin regeneration. It is essential to carefully follow post-treatment instructions and use high SPF sun protection.
For superficial peels, no anesthesia is needed: only a mild tingling or burning sensation is felt during application, which quickly subsides. For medium peels, a topical anesthetic cream may be applied to improve comfort. For deep phenol-based peels, local anesthesia or light sedation is required, as the treatment is more intense and requires monitoring during the procedure.
Results are progressive and depend on the type of peel performed. For superficial peels, the skin appears more radiant and smooth within a few days after peeling, with optimal results after a cycle of 3-6 sessions. For medium peels, improvement is evident 1-2 weeks after healing, with an effect that continues to improve in the following weeks due to collagen stimulation. Deep peels offer significant results after just a single session, with progressive improvement over the following 2-3 months.
The number of sessions depends on the type of peel and the imperfection being treated. For superficial peels, a cycle of 4-6 sessions spaced 2-3 weeks apart is recommended, with maintenance cycles 2-3 times per year. Medium peels generally require 2-3 sessions spaced 4-6 weeks apart. Deep peels are usually performed in a single session, given their greater intensity and long-lasting effect.
