When combining Microneedling with Latisse on a hypo-pigmented scar caused by a scratch, how long does the pigment last?

Question

Are maintenance treatments required so the pigment remains in the scarred area?

Nelson Lee Novick, MD · Answer

I have been employing manual microneedling (no need for the added expense and risks of RF microneedling) accompanied by the application of topical Rx latanoprost and tyrosine for many years already for treating hypopigmented scars with typically gratifying and long-lasting results. I generally microneedle a small area of normal skin around the scar in hopes of autotransplanting some healthy pigment producing cells into the scar area, which can then utilize the topicals to produce new pigment. Hope this helps and best of luck to you.

For a hypopigmented scar, combining microneedling with topical bimatoprost (Latisse) may stimulate repigmentation, but there is no reliable way to predict exactly how long the pigment will last. The available evidence is limited to small studies and case reports. Some patients have maintained improvement for many months after treatment, but the durability can vary depending on the depth and cause of the scar and whether the melanocytes were preserved.

In one reported case, repigmentation remained improved four months after completing treatment, while another case showed sustained improvement 10 months after the initial treatment.

I would therefore consider the result potentially long-lasting but not guaranteed to be permanent. Also, Latisse is FDA-approved for eyelash hypotrichosis, not for treating hypopigmented scars, so its use for scar repigmentation is considered off-label.
