Dr. Althea Vitamin C Boosting Serum 63% — 30ml

The Vitamin C Serum That Finally Works for Sensitive Skin.

Every skin type deserves the brightening power of Vitamin C — and the Dr. Althea Vitamin C Boosting Serum finally delivers it without the stinging, yellowing, or oxidation frustrations that put so many people off conventional Vitamin C serums. Built on a 63% Hippophae Rhamnoides Water base — Sea Buckthorn, one of nature's most Vitamin C-rich botanicals — this is a serum that floods your skin with potent brightening actives, 8 types of Hyaluronic Acid, and a complete 9-Vitamin complex, all in a lightweight, fragrance-free formula that even the most sensitive skin tolerates beautifully.

A high-potency brightening serum formulated with 63% Hippophae Rhamnoides Water and 5% Niacinamide — with just two weeks of use, it helps reduce dullness and pigmentation, revealing a brighter, more even complexion.

What It Does

Brightens Visibly in Two Weeks — Contains 640,000 ppm of Hippophae Rhamnoides Water, rich in Vitamin C, to help even out skin tone and revitalize dull, tired-looking skin — 

Fades Dark Spots & Hyperpigmentation — Formulated with 5% Niacinamide and 2% Tranexamic Acid, it helps reduce dullness and dark spots for a brighter, more even-toned complexion.  The triple-action brightening complex targets pigmentation from every angle — suppressing melanin production, interrupting melanin transfer, and fading existing spots simultaneously.

Deeply Hydrates Without Stickiness — Formulated with Centella Asiatica and 8 types of Hyaluronic Acid to calm and deeply hydrate skin  — delivering simultaneous surface and deep-layer moisture that keeps skin plump, bouncy, and comfortable all day with no residue.

Soothes & Calms Sensitivity — Centella Asiatica Leaf Water helps to relieve stressed skin caused by environmental factors, supporting the recovery of weakened skin while enhancing firmness and resilience. 

Refines Pores & Controls Sebum — Formulated with Niacinamide to help control sebum production and refine pores to smooth out uneven skin texture without leaving the skin dry.

No Yellowing & No Unpleasant Odor — Free from the discoloration and off-putting scent often found in Vitamin C serums — one of the most common complaints about conventional Vitamin C formulas, solved entirely by using stable Vitamin C derivatives and Sea Buckthorn as the base.

Key Ingredients

Hippophae Rhamnoides Water — 63% (Sea Buckthorn) — The extraordinary foundation of this formula and the reason it outperforms conventional Vitamin C serums. Rich in Vitamin C, this natural ingredient brightens the complexion and improves skin texture, luminosity, and reduces dullness. - Sea Buckthorn contains over 200 times more Vitamin C content than apples — and 3.2 times more than lemons — alongside Vitamins A, E, K, and a complete fatty acid profile that delivers antioxidant protection, barrier nourishment, and brightening action simultaneously. At 63%, it forms the formula's base rather than a supporting note.

Niacinamide — 5% — At the clinically validated concentration for maximum efficacy, Niacinamide interrupts melanin transfer pathways, fades dark spots, minimizes pores, regulates sebum, and strengthens the barrier — amplifying every other brightening active in the formula.

Tranexamic Acid — 2% — Known for its brightening effects, it helps reduce hyperpigmentation and the appearance of dark spots and even out the skin tone.  A gentle but highly effective brightening active that works upstream in the melanin pathway — particularly effective for melasma and post-inflammatory hyperpigmentation.
