== Chemical peel vs. laser resurfacing ==

Chemical peels and laser resurfacing are dermatological procedures used to improve skin texture, tone, and appearance by removing damaged outer layers of the integumentary system. While both treatments aim to stimulate the growth of new skin cells and collagen, they utilize different physical mechanisms to achieve these results. Selection between the two methods often depends on the patient's specific skin concerns, skin type as measured by the Fitzpatrick scale, and the required depth of treatment.<ref>American Society of Plastic Surgeons. "Chemical Peel vs. Laser Resurfacing."</ref>

=== Mechanism and application ===

Chemical peels utilize acidic solutions to exfoliate the skin. A practitioner applies a chemical agent, such as glycolic acid, salicylic acid, trichloroacetic acid (TCA), or phenol, to the surface of the skin. This causes a controlled chemical burn that leads to the eventual peeling of the epidermis or dermis. The depth of the peel is determined by the concentration of the acid and the duration of its contact with the skin. Light peels target only the epidermis, while deep peels reach the mid-reticular dermis to address more significant imperfections.<ref>American Academy of Dermatology. "Chemical peels: Overview."</ref>

Laser resurfacing employs concentrated beams of monochromatic light to create controlled thermal injury. There are two primary categories of laser treatment: ablative and non-ablative. Ablative lasers, such as carbon dioxide (CO2) or Erbium (Er:YAG) lasers, vaporize the surface skin cells to trigger a healing response. Non-ablative lasers, including various fractional or pulsed-dye lasers, penetrate the skin surface to heat underlying tissues without removing the top layer. Lasers offer high precision, allowing clinicians to target specific areas like periorbital wrinkles or acne scars without affecting surrounding healthy tissue.<ref>Mayo Clinic.

=== Safety and contraindications ===

Both procedures carry risks, including infection, scarring, and changes in skin pigmentation. Patients with darker skin tones (Fitzpatrick types IV–VI) are at a higher risk of post-inflammatory hyperpigmentation (PIH) or hypopigmentation following aggressive treatments. Deep chemical peels using phenol require cardiac monitoring during the procedure due to the risk of systemic absorption and potential heart arrhythmias.<ref>Journal of Clinical and Aesthetic Dermatology. "Safety and Efficacy of Resurfacing Procedures."</ref>

Laser resurfacing may trigger the reactivation of the herpes simplex virus if prophylactic antiviral medication is not administered. Patients with active acne, certain autoimmune conditions, or those who have recently used isotretinoin may be advised to postpone either treatment to avoid complications during the healing process.
