Description
Pure vitamin C serums can sting, so Dr. Althea took a gentler route with this one. Instead of high-strength ascorbic acid, it uses 3-O-ethyl ascorbic acid, a stable vitamin C derivative, together with sea buckthorn fruit extract (listed at 20%) and niacinamide. The brand describes it as a lightweight, fast-absorbing serum designed to brighten dull-looking skin, improve the look of dark spots and support a more even-looking complexion.
The texture is light and non-sticky for daily use, and green tea leaf water and allantoin are included for a comfortable feel.
Key ingredients
- Hippophae rhamnoides (sea buckthorn) fruit extract – the base of the formula.
- 3-O-ethyl ascorbic acid – a stable vitamin C derivative.
- Niacinamide – associated with a brighter, more even-looking tone.
- Green tea leaf water, allantoin and adenosine – for a calm, smooth feel.
How to use
- After cleansing and toning, apply an appropriate amount to the face.
- Pat gently until fully absorbed.
- Follow with moisturizer, and use sunscreen during the day.
Who it suits
Aimed at dull-looking or uneven-toned skin and described as suitable for sensitive skin. Works for normal, combination and oily skin as a daytime or nighttime serum.
Good to know
Size: 30 ml. Brightening results depend on consistent use and daily sun protection. Introduce it gradually if you are already using other strong actives.
As with any new skincare product, patch-test on a small area (for example behind the ear or along the jaw) for 24–48 hours before using it on the whole face. Stop using it if redness, itching or stinging persists, and avoid applying it to broken or irritated skin. Always check the full ingredient list on the packaging you receive, as formulas can be updated by the brand.
