Dr.Althea Vitamin C Boosting Serum — Seabuckthorn (640,000 ppm) with TXA & Niacinamide for Brightening

Dr.Althea Vitamin C Boosting Serum is a lightweight daily serum that combines stabilized vitamin C from seabuckthorn water with tranexamic acid and niacinamide to help reduce the appearance of dark spots and even skin tone.

This concentrated face serum blends 640,000 ppm Hippophae rhamnoides (seabuckthorn) water, tranexamic acid (TXA), niacinamide, and soothing Centella asiatica water into a non-sticky, odor-free formula. Designed to absorb smoothly and layer easily under moisturizers or SPF, it balances brightening actives with gentle botanicals so sensitive and combination skin types can incorporate it into a daily routine without the usual discoloration or strong citrus scent of raw vitamin C.

How does this serum target dark spots and uneven pigmentation?

The formula pairs tranexamic acid with niacinamide and a vitamin C–rich ingredient to address multiple aspects of visible discoloration. Together they help improve the look of hyperpigmentation, post-inflammatory marks, and general dullness when used consistently.

• Tranexamic acid helps reduce the visible intensity of dark spots associated with skin discoloration.
• Niacinamide regulates sebum and refines pore appearance for smoother texture.
• Seabuckthorn (Hippophae) water delivers natural, stabilized vitamin C for antioxidant support and brighter-looking skin.
• Centella asiatica calms stressed or irritated skin while supporting recovery.

Is this serum suitable for sensitive or acne-prone skin?

Yes — Dr.Althea designed this serum to be gentle: the seabuckthorn water provides vitamin C in a milder form than pure ascorbic acid, and soothing Centella helps reduce irritation. Niacinamide also helps balance oil production without drying, making it compatible with many sensitive and acne-prone routines.

• Free from artificial colors, fragrances, and parabens to lower irritation risk.
• Lightweight, non-sticky texture that layers well with other treatments and sunscreen.
• Vegan-certified ingredients for ethical formulation choices.

How should I use the serum in my daily skincare routine?

Apply the serum once or twice daily after cleansing and toning, then follow with moisturizer and SPF in the morning. A small amount spreads easily over face and neck; allow a moment for absorption before layering other products.

• Use 2–3 drops for the entire face; increase slightly for drier skin as needed.
• Morning use requires sunscreen to protect newly brightened skin from UV exposure.
• Can be combined with other serums — apply lightest formulas first and observe any sensitivity when mixing strong actives.

What results can I expect and when?

Visible changes vary with skin type and consistency, but many users notice improved brightness and smoother texture within weeks. For diminishing stubborn dark spots, sustained use over several months produces the most reliable improvement.

• Initial boost in skin radiance and hydration often seen within 1–3 weeks.
• Improved skin tone uniformity and reduced appearance of some dark marks in 6–12 weeks.
• Best results when used consistently with sun protection and gentle exfoliation as appropriate.

Who is this for: Dr.Althea Vitamin C Boosting Serum suits anyone seeking a gentler vitamin C option to brighten skin, target hyperpigmentation, and refine pores without heavy fragrances or sticky residues. It works well for sensitive, combination, oily, and mature skin types who want a daily, vegan-certified addition to their morning or evening routine.
