What should you know about TCA 25 peel?

TCA 25 is not a casual home skincare product. The clinician considers the diagnosis, skin tone, treatment area, barrier condition, medical history, and previous pigment response before deciding whether to use it. It may be considered for selected scars or surface changes, while active inflammation, infection, or unexplained pigmentation may require another approach.

Expect a noticeable chemical sensation and a healing phase with redness, tightness, crusting, and peeling. Inflammation can leave darker or lighter areas, particularly in people prone to post-inflammatory hyperpigmentation or melasma. The provider should explain the planned endpoint and follow-up.

Give a full list of medicines, skin products, allergies, cold sore episodes, recent sun exposure, and recent procedures. Do not apply a concentrated peel yourself or add retinoids, acids, bleaching agents, or scrubs unless the clinician specifically schedules them.

Follow the written aftercare plan, wash gently, and keep the area moisturised. Never peel off crusts. Avoid friction, heat, swimming, strenuous activity, fragrance, and sunlight while the skin is healing. Use sun protection as directed and attend the planned review before changing routine.

Contact the provider promptly for worsening pain, marked swelling, spreading redness, pus, fever, extensive blisters, or delayed healing. Seek emergency care for breathing difficulty, severe facial swelling, or chemical contact with the eye.

Ask what diagnosis is being treated, why this strength is being considered, whether a gentler option is safer, how pigment risk will be managed, how long to avoid sun and active products, and who will assess you if healing changes.
