What It Is: A collagen-support serum built around Hydrolyzed Collagen, paired with Vitamin C (Ascorbic Acid), niacinamide, and hyaluronic acid for firmness and hydration in one step. This is a more concentrated form of Vitamin C than our Vitamin C Serum uses — Ascorbic Acid rather than a gentler derivative — so it's a good fit for skin that's already comfortable with actives.

Best For Anti-Aging and Hydration. If firmness and moisture are both on your mind, this is the one serum that addresses both instead of asking you to buy two.

How It Fits Your Routine: A 3-step routine involves Cleanse, Treat, and Protect. This is step 2 of 3. Works well as a night step, paired with SPF the following morning — Ascorbic Acid can make skin more sun-sensitive, so morning SPF isn't optional here.

Before You Start: Patch test first. Apply a small amount to your inner arm or behind your ear and wait 24 hours before using on your face. If you notice redness, itching, or irritation at any point, discontinue use immediately and consult a dermatologist. For external use only — avoid contact with eyes, and rinse thoroughly with water if contact occurs. Keep out of reach of children. Store in a cool, dry place, away from direct sunlight.
