Acne Scarring Treatment in Marylebone, London

Realistic expectation for a combination protocol delivered over 12 months is 50 to 70% improvement in overall scar severity. Complete removal is rarely achievable because the collagen damage is structural, but the visual impact of a well-executed protocol is often transformative — especially when paired with improvements in skin quality, pigmentation, and surface texture that the same treatments also deliver.

TCA CROSS (trichloroacetic acid chemical reconstruction of skin scars) is the gold-standard treatment for ice-pick scars. A tiny amount of 70% TCA is applied pinpoint to each individual scar, inducing controlled necrosis and subsequent collagen remodelling. Typically 4 to 6 sessions spaced 6 weeks apart produce 40 to 60% improvement per treated scar, and the technique is safe for darker skin types (unlike broad-surface ablative lasers).

A typical combination protocol for moderate acne scarring runs over 9 to 12 months — for example, 4 TCA CROSS sessions every 6 weeks alongside 3 fractional non-ablative laser sessions every 8 weeks. Improvements continue to develop for 3 months after the final treatment as collagen remodels. Expect visible change by session 2 to 3, with the full protocol effect assessed at the 12-week post-final-session review.

Yes, with appropriate device and protocol selection. TCA CROSS, medical microneedling, and carefully selected non-ablative lasers are all safe for Fitzpatrick IV–VI skin. Devices that risk post-inflammatory hyperpigmentation (certain ablative lasers, IPL) are avoided. Pre-treatment with tyrosinase inhibitors for 4 to 6 weeks is typically added to reduce PIH risk further.
