The Universal C serum draws praise for lightweight, silky texture, effective brightening, and improved skin texture over time.

Some users report mixed hydration and occasional stinging, along with concerns about pump functionality and price.

Estheticians on Reddit call it “12/10,” and reviewers note noticeably smoother, glowing skin.

Overall takeaway: premium, high‑potency vitamin C serum that works—but may not suit all skin types or budgets.
