Dr.Althea Vitamin C Boosting Serum with Tranexamic Acid

This serum delivers targeted active ingredients — such as hyaluronic acid, niacinamide, retinol, or vitamin C — deep into the skin to address specific concerns like hydration, brightening, anti-aging, or barrier repair.

Apply serums after cleansing and toning but before moisturizer. Use morning or evening depending on the active ingredient — vitamin C serums work best in the morning, while retinol and AHA serums are best used at night.

Typically 2–3 drops or a pea-sized amount is enough to cover the full face. Serums are concentrated, so using more will not improve results and may increase the chance of sensitivity.

Most serums in our range are formulated without fragrance and are dermatologist-tested, making them suitable for sensitive skin. Always perform a patch test before applying to your full face, especially with active ingredients like acids or retinol.

Most serums show initial improvements in hydration and texture within 1–2 weeks. For more significant results with concerns like pigmentation, fine lines, or acne, allow 4–8 weeks of consistent daily use for full visible benefits.
