The one you'll still be using in March.
High-strength vitamin C is more potent and most people abandon it inside a month - it stings, then it goes brown in the bottle. A stabilised form trades peak strength for daily tolerability, which for an ingredient that works through consistency is the better bargain.
- Stable form
- No sting
- Daily use
How it feels
A light serum that absorbs cleanly with no tack and no warmth on application - the practical difference from L-ascorbic acid.
Key ingredients
Stabilised Vitamin C
A derivative rather than L-ascorbic acid. Less potent per application, but it does not sting and does not oxidise in the bottle.
Niacinamide
A second brightening route that also supports the barrier, which is what allows daily use.
Hyaluronic Acid
Offsets the mild dryness that follows sustained use of any brightening active.
About the product
Dr.Althea's Vitamin C Boosting Serum makes a trade that most people should take.
Pure L-ascorbic acid is the most potent and best-studied form of vitamin C. It also stings, oxidises quickly, and is abandoned by a large proportion of the people who buy it - usually within a month. A serum sitting unused in a drawer has an effectiveness of zero regardless of its concentration.
This uses a stabilised vitamin C derivative instead. Less potent per application, but no sting, no oxidising, and therefore a product people actually finish. For an ingredient that works through consistency over months rather than intensity in a week, that is the better bargain.
Niacinamide provides a second brightening route while supporting the barrier, and hyaluronic acid offsets the mild dryness sustained brightening causes.
Use once or twice daily after cleansing, before moisturiser. If you use it in the morning, sunscreen over the top is essential - brightening actives and UV work directly against each other.
Why we stock it
The gentle end of our vitamin C range, and the one we recommend to most people. Trading peak strength for daily tolerability is the right trade for an ingredient that only works if you keep using it.

Frequently asked questions
Is a derivative as good as L-ascorbic acid?
Less potent per application, but far more tolerable and stable. Since results come from months of consistent use, most people get a better outcome from a derivative they keep using.
Will it oxidise like other vitamin C serums?
No - stability is the main advantage of a derivative. It will not turn brown in the bottle the way L-ascorbic acid does.
Morning or night?
Either, or both. Morning use pairs the antioxidant effect with the day's UV exposure, but only with sunscreen over it.
Can I use it with niacinamide?
It already contains niacinamide. The old advice about not mixing the two is based on a misreading of decades-old research - modern formulas combine them routinely.
