Power-C Firming & Brightening Serum Capsules

These single-dose capsules deliver a potent 20% concentration of L-ascorbic acid to target dark spots and loss of firmness. The capsule format keeps the notoriously unstable vitamin C fresh and potent until the moment it hits your skin, which is a smart move for a high-strength formula. It’s a reliable choice for brightening dullness, though the high percentage means those with very reactive skin might want to patch test first.
