The Science Behind The Formula
The Science Behind The Formula
We built the formula around tetrahexyldecyl ascorbate for a reason: it’s one of the most bioavailable, stable forms of vitamin C. Unlike ascorbic acid, it won’t oxidize quickly or irritate sensitive skin. It penetrates deeper layers, converting to active vitamin C where your skin needs it most — delivering real results, not just surface glow.
Backed by clinical research. Grounded in gentle, effective delivery.
Key Ingredients
Key Ingredients
• Tetrahexyldecyl Ascorbate:
A stable, oil-soluble form that visibly fades discoloration, smooths texture, and boosts collagen for daily radiance — without the oxidation or irritation of traditional ascorbic acid.
• Tocotrienol (Super Vitamin E):
Defends against pollution, UV, and oxidative stress — preserving clarity, elasticity, and long-term skin health.
Brightens. Defends. Strengthens.
The signature balance of gentle and powerful — for glow that lasts through anything.

The Everyday Glow, Measured
After 28 days of daily use, our test group saw skin looking noticeably brighter and more even-toned. That's the point of a stable vitamin C formula — visible, everyday radiance from a comfortable daily dose.
Vitamin C That Actually Lasts
Most vitamin C oxidizes and fades within weeks of opening. Ours is built to stay active — holding nearly all of its potency for a full year after opening, so the last drop works as hard as the first.
Why THD Ascorbate
We use tetrahexyldecyl ascorbate — an oil-soluble, exceptionally stable form of vitamin C. It's gentle enough for daily use, won't sting or oxidize the way pure ascorbic acid can, and brings antioxidant defense and brightening in one comfortable step.
What's THD ascorbate, and how is it different from regular vitamin C?
THD (tetrahexyldecyl ascorbate) is an oil-soluble, highly stable form of vitamin C. Unlike pure ascorbic acid — which can sting, oxidize quickly and turn brown — THD stays stable, absorbs comfortably into an oil base, and is gentle enough for sensitive skin and daily use. You get the glow of vitamin C without the drama.
How do the strengths differ?
This is our signature 10% formula — the balanced daily dose that works for most skin. If you're new to vitamin C or have very sensitive skin, Gentle (7%) offers a softer introduction. If your skin is experienced with actives and wants more intensity, Intensive (20%) and Clinical (30%) are the next steps. Most people start here and stay here.
When and how do I use it?
Use 2–3 drops on clean skin, morning or night, after your water-based serums and before your moisturizer or SPF. It layers happily under sunscreen for the day, and a drop mixed into foundation gives a dewy finish. A little goes a long way.
Will it sting or irritate sensitive skin?
It's designed not to. Because it's oil-soluble THD rather than pure ascorbic acid, there's no water, no acidity and no sting — it's dermatologically tested and made with sensitive skin in mind. As always, patch test before first use and keep it away from the eyes.
What is the shelf life?
Unlike traditional vitamin C that oxidizes within weeks, our THD ascorbate formula maintains nearly 95% active potency for up to a year after opening. The two-year unopened shelf life is just extra peace of mind.
Can I use it alongside my other actives?
Yes — it sits comfortably in most routines and layers well under SPF. If you're also using strong actives like retinol or exfoliating acids, introduce them on alternating days at first so your skin can adjust, then build the combination that feels good.
