As of May 12, 2026, The Vitamin C 23 Serum is cheapest at Cupidrop for $17.50.
A high-strength brightening serum with 23% pure vitamin C (L-Ascorbic Acid), a potent antioxidant that helps fade dark spots and even out skin tone over time.
The lightweight formula absorbs quickly and includes hydrating ingredients to keep skin comfortable.
Best used in your morning routine followed by SPF.
Suitable for all skin types looking to tackle dullness, uneven tone, or dark spots.
Especially helpful if you've used vitamin C serums before and want to level up to a higher concentration—though if you're new to actives or have reactive skin, a patch test is a good idea.
