[so natural] Red Peel White Serum 35ml

5% niacinamide, tranexamic acid, glutathione, PHA, vitamin C support, and sodium hyaluronate target tone and hydration together.

This serum uses a classic multi-path brightening strategy. Niacinamide at 5% is a practical daily level for supporting a more even-looking tone, helping reduce the look of dullness while remaining easier to tolerate than stronger one-note actives. Tranexamic acid and glutathione add to that brightening logic from different angles, which is why formulas pairing them are often used for skin that looks uneven or tired. PHA contributes gentle surface exfoliation, helping loosen dull buildup so the skin reflects light more evenly, while sodium hyaluronate offsets that process with water-binding hydration. The result is a formula that addresses both tone and texture instead of treating them as separate problems. The note about wearing it under makeup also makes sense cosmetically, because smoother, better-hydrated skin usually gives a cleaner finish under base products. Scientifically, the product is best understood as a daily brightening serum for gradual clarity, smoother texture, and a more hydrated glow rather than an instant pigment eraser.
