Green Tea Enzyme Vitamin C Brightening Serum — Reddit Reviews
by innisfree
Updated October 3, 2026
3-O-ethyl ascorbic acid brightens dark spots fast; sometimes disappoints.
What the community says
A vitamin C serum built around 3-O-ethyl ascorbic acid, plus niacinamide, glutathione, ferulic acid, and panthenol. People chasing sun spots or melasma lean toward it; if you want instant HG-level pigment fading, YMMV.

What the studies found
- Most studies found vitamin C helped fade dark spots or patches
- In melasma studies, vitamin C on the skin often made patches look lighter over time
- Used with other treatments, vitamin C sometimes faded melasma more than the other treatment alone
- For sun spots, vitamin C showed some fading, but one study had mixed results
- It worked about as well as glycolic acid for fading melasma patches in one large review
Research context, not treatment advice. Studies are about the ingredient, not necessarily this exact product.
