Is ethyl ascorbic acid as good as regular vitamin C?

It is a derivative that converts to vitamin C in skin. It is more stable and gentler, but typically works more slowly than 15-20% L-ascorbic acid serums.

Can I use it while pregnant or breastfeeding?

Alpha-H markets this serum as pregnancy and breastfeeding safe. Check with your doctor if you have specific concerns.

When should I apply it?

Use it in the morning on clean skin before moisturizer and sunscreen. Daily sunscreen is essential with any vitamin C routine.

How long does the 0.85 oz bottle last?

With one daily application of a few drops, expect roughly one to two months of use.

$57 at eBay as of November 5, 2026 is the best of five stores listing it new. Compare per-ounce cost, since the bottle is only 0.85 oz.

Our take on the Alpha-H Vitamin C Serum with 10% Ethyl Ascorbic Acid

Alpha-H Vitamin C Serum is a lightweight daily brightening serum built on 10% ethyl ascorbic acid, a more stable vitamin C derivative, plus hyaluronic acid for hydration. It is marketed as vegan, cruelty-free and pregnancy and breastfeeding safe, and suits all skin types. The 0.85 oz bottle is small, so at $57 at eBay as of November 5, 2026 it is a premium buy per ounce.
