Hi all! I’m 30F, half white/black African with oily spot prone skin that has a few dark scars left from hormonal acne which has cleared up after treatment at the start of the year. My most recent routine consisted of PC’s BHA, TO Niacinimide, PC’s Azealiac Acid and LRP’s moisturiser and it worked really well for me, but I’m now wanting to incorporate TO’s Alpha Arbutin but I’m not sure how/where. Would adding it to my current routine be too many products? Should I swap it with the Niacinimide or Azealiac Acid? Any advice would be greatly appreciated, thanks!
