I'm 32 (F) and have had severe acne after stopping birth control. It improved after taking Isotretinoin for 9 months. Now, I'm concerned about skin discoloration on my cheeks (pigmentation, scars, red marks). My routine includes sun protection, Vitamin C, and Differin 0.1%. I've been recommended treatments like CO2 Laser, PRP Lifting, Radiofrequency Microneedling, Vbeam, Q-Switch, and Pico Laser. Which method or combination do you reckon is best for me?
