Brightening Renewal Serum for Hyperpigmentation, Redness & Healthy Aging

Transform your skin with Circadia Serum 71 Renewal Serum, an advanced professional treatment designed to brighten uneven skin tone, reduce the appearance of discoloration, calm visible redness, and support firmer, healthier-looking skin. This multitasking serum combines tranexamic acid, mandelic acid, azelaic acid, beta glucan, and copper peptides to improve skin clarity while strengthening the skin’s natural barrier.  

Unlike harsh treatments that focus on just one concern, Serum 71 targets multiple skin challenges at once—helping improve the appearance of post-acne marks, melasma, uneven texture, fine lines, and visible redness while supporting collagen and elastin production for smoother, more resilient skin.  

As a Licensed Esthetician and Certified Acne Expert, I recommend this serum to clients looking for a professional solution that addresses pigmentation, aging, and overall skin health without compromising the skin barrier.

How to Use
