Benton - Vitamin C Serum 30ml

Benton Vitamin C Serum — 20%, and What That Number Costs You

Vitamin C serums come in a range, and the number is not a score. Ten per cent is a gentle starting point. Twenty is the upper end of what skin generally tolerates, and it is where the visible results live. It is also where the tingle lives, and the reason you do not hand this to someone with a compromised barrier.

The Benton Vitamin C Serum is 30ml at 20% pure Vitamin C, in a lightweight milky formula that absorbs instantly.

What's In It

20% pure Vitamin C and glutathione lift dullness and work on the look of hyperpigmentation.

The support cast is the interesting part. Ferulic acid and Vitamin E bring antioxidant benefits — and ferulic acid is not decoration, it is the ingredient that keeps vitamin C stable, which is the entire weakness of the category. Adenosine works on a smooth, wrinkle-free finish.

Who It's For

Skin that looks dull, grey or unevenly pigmented, and anyone who has tried a gentle vitamin C and wanted more from it.

Not a first serum if your skin is reactive or your barrier is in a bad way — 20% is the deep end. Fix the barrier first: Damaged Skin Barrier and how to repair a damaged skin barrier cover the order.

Benton's other serum, the Bakuchiol Serum, targets fine lines rather than tone. Many routines run this one in the morning and that one at night. Both in the Benton collection. See also vitamin C, Korean Serums, Brightening & Even Skin Tone and Sun Damage & Pigmentation.

How to Use It

1. Cleanse and tone first.
2. Apply a few drops to dry skin, avoiding the eye area.
3. Let it absorb, then follow with moisturizer.
4. Start two or three mornings a week and build up. At this strength, easing in is not optional.
5. Keep it capped and out of light — vitamin C oxidises, and a serum that has turned brown has stopped working.

Then sunscreen, without exception. Vitamin C and unprotected UV cancel each other out — you would be paying for brightening and undoing it before lunch. See the 2026 SPF guide.

Questions

Is 20% too strong for me?
It might be. It is the upper end of what skin generally tolerates. If yours is sensitive or your barrier is struggling, start elsewhere.

Morning or night?
Morning, under sunscreen, is the usual choice — the antioxidants complement your SPF.

Why ferulic acid?
It stabilises vitamin C. Vitamin C degrades easily, and ferulic acid is what keeps the formula doing its job.

Can I use it with the Bakuchiol Serum?
Yes, on separate ends of the day. Vitamin C in the morning, bakuchiol at night.
