SkinCeuticals SkinLab on Tennyson St is where you go when you're done guessing with drugstore serums and ready for an actual skin strategy. This is a medical-grade facial and skincare spot backed by The Center for Cosmetic Surgery, so the estheticians know their stuff and the treatment menu goes deep: chemical peels, microneedling, laser treatments, and facials built around what your skin actually needs, not just what sounds trendy. The space feels clean and clinical in the best way, calm and bright without being sterile. People rave about the staff here, and a 5 star rating across 246 reviews doesn't happen by accident. It's a favorite for Berkeley locals who treat skincare like a long game, brides prepping months out, and anyone who wants real results explained in plain language instead of upsold jargon.
