Chemical Peel (Express Beauty / Glycolic Acid)

Professional glycolic acid chemical peeling at EsteticUsti removes damaged upper skin layers and stimulates new cell formation — targeting pigmentation irregularities, post-acne scarring, fine wrinkles, sun damage, enlarged pores, and uneven texture. The peel is applied by a doctor, neutralised at the correct timing, and results are visible after each session, with cumulative improvement across a treatment series. Unlike at-home acids, this medical-grade application reaches a deeper, more effective skin layer under controlled conditions. EsteticUsti's 'Express Krása' protocol delivers a full glycolic peel as a clinic appointment that requires no prior skin preparation and allows patients to return to social activities quickly.

Glycolic acid is an alpha-hydroxy acid (AHA) derived from sugar cane, with the smallest molecular weight of any AHA — enabling rapid, deep penetration into the stratum corneum and upper epidermis. At medical concentrations (typically 30–70%), glycolic acid disrupts corneocyte cohesion by breaking the ionic bonds between keratinocytes, triggering controlled desquamation of the outermost cell layers. This is followed by upregulation of epidermal growth factor and increased fibroblast activity in the dermis, resulting in a denser dermal matrix, thicker epidermis, and improved collagen content over a treatment series. The clinical effect depends on acid concentration, contact time, and pH — all controlled by the treating physician at EsteticUsti. The application protocol involves cleansing the skin, applying the acid preparation, monitoring the patient for the desired frosting or erythema endpoint, then neutralising with a sodium bicarbonate solution and rinsing thoroughly. After neutralisation, a protective cream and mineral sunscreen are applied. The physician tailors the contact time based on skin sensitivity and response at each visit. The recommended EsteticUsti protocol for the Express Krása programme is 5 sessions, with 2–4 treatment courses per year. Individual improvements are visible after each session: reduced pigmentation, improved texture, brighter complexion, and softer fine lines. Cumulative sessions progressively reduce post-acne scarring depth and normalise melanin distribution in sun-damaged skin. Mandatory home skin preparation (prescription retinoid or AHA pre-treatment) may be recommended between sessions by the physician. Post-peel mandatory sun protection prevents new pigmentation. Patients with a tendency to prolonged post-inflammatory hyperpigmentation (common in Fitzpatrick IV+) and those taking photosensitising medications should discuss suitability at consultation.
