Double Vitamin C Serum

When skin looks flat and tired, vitamin C is the ingredient most people reach for. The Double Vitamin C Serum pairs pure ascorbic acid with hyaluronic acid and collagen, so it brightens while it hydrates, and it feels light enough to wear under moisturizer morning and night.

Trehalose and betaine help hold moisture, centella and beta-glucan keep skin comfortable, and witch hazel with aloe vera leaves a fresh finish. The 30 ml bottle is easy to add to any routine, and it layers well with the rest of our face serums.

If dark spots are your main concern, compare it with our Dark Spot Correcting Serum.

A fresher, brighter look: pure vitamin C is a classic choice for dull skin.

Hydration alongside brightening: hyaluronic acid and collagen help skin feel plump and soft.

Smooths the look of fine lines: consistent use helps skin look more even and refined.

Comfort built in: centella, beta-glucan, aloe and witch hazel keep the formula balanced.

Light enough for twice daily: a single quick step in the morning and evening.

Step 1 — Cleanse and pat your face dry. If you use a toner, apply it before the serum.

Step 2 — Take a small amount on your fingertips and massage gently into your face until absorbed, avoiding the eye area.

Step 3 — Layer your moisturizer on top. In the morning, finish with sunscreen.

How often? Morning and evening. If your skin tingles, start with once a day and build up.

Patch-test first. For external use only. Keep sunscreen in your morning routine.

These are the main ingredients and what each one does.

Ascorbic acid (pure vitamin C): the classic brightening antioxidant, used for a fresher, more even-looking tone.

Hyaluronic acid: a hydrating ingredient that helps skin hold water.

Collagen: supports a plump, smooth feel at the surface.

Trehalose and betaine: moisture-binding ingredients that keep skin comfortable.

Centella asiatica and beta-glucan: calming ingredients that soothe the look of redness.

Witch hazel and aloe vera: a fresh, balancing finish.

Should I use vitamin C in the morning or at night?

Both work. Many people use it in the morning because it pairs well with sunscreen, but this formula is made for twice-daily use.

Can I use it with niacinamide?

Many people use vitamin C in the morning and niacinamide at night. If your skin tingles or reddens, use one at a time.

Does it sting?

A slight tingle can happen with pure ascorbic acid, especially at first. Start once a day and patch-test.

How long does a 30 ml bottle last?

With a few drops once or twice a day, it generally lasts several weeks.
