Dr. Althea serum care
Gentle Vitamin C Serum
Introduce a brighter-looking glow with a lightweight vitamin C serum that feels fresh rather than sticky. Sea buckthorn, niacinamide and a vitamin C derivative work on dullness and uneven-looking tone, while the oil-capsule texture adds comfortable moisture.

A gentle introduction
Start your brightening routine
Give dull skin a fresher, more even-looking finish without a rich or heavy layer. The watery serum spreads easily, making it an approachable first vitamin C step for a simple daily routine.
Inside the formula
Niacinamide, sea buckthorn and vitamin C
Niacinamide and 3-O-Ethyl Ascorbic Acid, a vitamin C derivative, focus on the look of uneven tone. The formula also contains sea buckthorn and green tea alongside moisturising ingredients.
What it does
A fresher, smoother-looking complexion
Hydration softens the look and feel of skin while brightening care addresses dullness and visible marks. The light finish fits beneath moisturiser without leaving a thick, glossy layer.
Skin comfort
Green tea care in a light serum
Green tea and allantoin bring soothing care to the formula. Introduce the serum gradually if your skin is sensitive or vitamin C is new to your routine, then continue at a frequency that feels comfortable.
Oil-capsule texture
Moisture that spreads smoothly
The oil-capsule system disperses as you spread the serum. Caprylic/capric triglyceride softens skin, while the watery base absorbs without a sticky finish. There is no need to break the capsules beforehand.
Tone-care results
A focus on visible pigmentation
A human application study assessed visible pigmentation and melanin changes after use. Keep brightening care consistent, moisturise afterwards and use sunscreen during the day.
Complexion results
Fresh radiance with regular use
The complexion assessment shown here followed two weeks of use. A simple routine makes the serum easy to use regularly: cleanse, apply the serum, moisturise and finish with sunscreen in the morning.
Choose your serum
Gentle Vitamin C or Vitamin C Boosting?
Choose Gentle Vitamin C Serum for an approachable brightening step with a fresh finish. Choose Vitamin C Boosting Serum when dark spots and lingering marks are your main focus. Start with one serum rather than layering both at once.

Frequently asked questions
Is this a good first vitamin C serum?
Its lightweight, non-sticky formula provides an approachable introduction to brightening care. Start every other day and increase gradually as your skin feels comfortable.
