Why 20%

The right dose, not just a big number.

Dermatology research shows vitamin C needs to be above 8% to make a real difference, and the most effective products sit between 10% and 20%.1 We use 20%, the top of that range.

The science behind it

Two ingredients. Each one doing real work.

A short formula built around the most researched form of vitamin C, with hydration so it never feels tight.

20%Concentration Honey-gold vitamin C serum swipe
The brightener

20% L-Ascorbic Acid

The most abundant antioxidant in healthy skin. It helps neutralize damage from sun and pollution, slows the enzyme behind dark spots, and is a building block your skin needs for collagen.1

Hydrator Bubbly clear hydrating gel
The hydrator

Sodium Hyaluronate

A form of hyaluronic acid that pulls water into skin. In a 60-day study, hyaluronic acid creams improved hydration and elasticity, and smaller molecules softened the look of fine lines.2

How to use

Mornings, in under a minute

1
Morning

After cleansing, smooth 3–4 drops over face and neck.

Layer

Follow with Under Eye Serum and Restoring Moisturizer.

3
Protect

Finish with SPF. Vitamin C helps defend against sun damage, but it isn't a sunscreen.

Questions

You might be thinking…

A light tingle for the first few uses is normal with pure vitamin C. If your skin is sensitive, start every other morning. We stop at 20% because research shows going higher adds irritation without adding benefit.1

Pure vitamin C naturally darkens as it meets air and light. That's true of every L-ascorbic acid serum. Keep the cap on and store it away from heat and sunlight.

Many budget serums use vitamin C derivatives, which the research is weaker on. This is pure L-ascorbic acid, the form most studies are based on.

The best-known prestige vitamin C serum is 15% in a 1 oz bottle for about $185. Ours is 20% in 1.7 oz for $84, or $58 with membership.

Yes. It's lightweight, fast-absorbing, and helps fade the look of post-blemish marks.

Your serum ships every 30 days for $58 instead of $84 (31% off), with a free gift and free shipping. No contract. Pause or cancel anytime.

I was skeptical at first, but after using this line for a few weeks, my skin is visibly clearer and much more even.

I love the texture and how it absorbs without feeling heavy. I'm so glad I gave it a try!
