Dr. Althea Vitamin C Boosting Serum
Details
Dr. Althea's Vitamin C Boosting Serum is a brightening treatment built around a 63% Sea Buckthorn Water base paired with 5% Niacinamide and 2% Tranexamic Acid, aimed at fading the look of dark spots, post-blemish marks, and dull, uneven tone. Alpha-Arbutin and stabilized vitamin C (3-O-Ethyl Ascorbic Acid and Ascorbic Acid) work alongside the niacinamide and tranexamic acid to reinforce the brightening effect from multiple angles. The lightweight, hydrating texture is formulated without artificial colors or fragrance, making it approachable for skin that's still building tolerance to vitamin C. It layers easily into a routine after toner and before moisturizer, and is gentle enough to introduce gradually. As with any vitamin C or brightening step, daytime use calls for consistent sunscreen.
Key Ingredients
Niacinamide (5%) — Helps improve the look of pigmentation and uneven tone.
Tranexamic Acid (2%) — Targets the appearance of dark spots and post-blemish discoloration.
Sea Buckthorn Water (63%) — Forms the hydrating botanical base of the formula.
Alpha-Arbutin & Vitamin C — Add further brightening support alongside the lead actives.
How to Use
Apply after cleansing and toning, once skin is fully dry. Use the dropper to smooth a few drops evenly over the face, patting gently until absorbed, then follow with moisturizer. If you're new to vitamin C, start every other day and increase frequency as your skin builds tolerance — and always finish daytime routines with sunscreen.
