How long do I have to wait to use an LED light after Derma Rolling?

Thanks for your query. Wait for at least a fortnight after Derma roller as it can cause PIH. For more query you can show to a dermatologist. Hope it helps.All The Best

There is no waiting time. In my office, we use the ProCell Therapies system and we often combine micro-needling treatments with LED treatments at the same time.Studies have shown that micro-needling should not cause post-inflammatory hyper-pigmentation (PIH), even in higher risk skin types.
