TCA CROSS for enlarged pores: what to know

A pore can look prominent because of oil, congestion, loss of firmness or sun-related texture. A narrow, sharply indented acne scar can also resemble an enlarged pore, but the treatment choice is different. TCA CROSS places a strong chemical solution into selected depressions to stimulate repair in the scar base; it is not a general pore-tightening wash or a treatment for every visible pore.

A clinician may examine the skin in different lighting and assess active acne, pigment tendency and scar depth before recommending a procedure. If active breakouts are contributing, treating [Acne](/conditions/acne/) may come first. Sun exposure can also influence texture and colour; information about [Sun-Damaged Skin](/conditions/photoaging/) may help put the concern in context.

Bring clear photographs and describe whether the openings are present at rest, after cleansing and across different areas of the face. Do not use a strong acid at home to copy a clinic procedure. Depending on the finding, a clinician may discuss [Microneedling](/treatments/aesthetic-procedures/microneedling/) or [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) rather than TCA CROSS. Daily sun protection and a non-irritating routine support the skin while the cause is being clarified.

Arrange a dermatology assessment if the texture is changing quickly, accompanied by persistent inflammation, bleeding or a painful lump, or if repeated picking is causing wounds. After any procedure, spreading redness, worsening pain, pus, fever or eye-area swelling needs prompt clinical advice.

Ask whether the openings are true pores, acne scars or another texture concern; what improvement the proposed treatment targets; how pigment changes will be prevented; and which alternatives suit your skin.
