Hi. I am using an IPL device at home (Philips Lumea Prestige) for over a year now and I also recebtly started to use an over the counter retinol (the one from The Inkey List). Next week I am going to have my maintanance treatment on my face and I was wondering if I should stop using the retinol. I used acids in the past and done right the next day my treatments with IPL just because I forgot and nothing happened to my skin. But would that have side effects on long term? Thank you!
