I've been using 0.025% tretinoin cream for a year. I mix 2 rice grain size of tretinoin with moisturizer and apply every night. My face gets slight pink but minimal peeling. I had an IPL for telangactasia without stopping Retin A with no issues. I'm thinking about switching to smooth beam 1450nm diode laser for acne as well as v-beam laser for redness/telangactasia. Should I still stop Retin A for both lasers if I was fine with IPL?
