Freshly Juiced Vitamin Drop — Reddit Reviews
by Klairs
Updated September 24, 2026
5% ascorbic acid serum for gentle brightening; oxidizes fast and can feel greasy.
What the community says
A 5% ascorbic acid serum that people use for morning brightening and post-acne spots. It suits sensitive skin better than hardcore L-ascorbic acid chasers, but oxidation and a greasy feel keep it from being universal.
What this means for you
Backed by 14 threads from r/SkincareAddiction, r/AsianBeauty and 2 more.
Read the threads ↓What people love
- 5% ascorbic acid — gentler than the usual acid gauntlet
- Sensitive-skin friendly brightening
- Didn’t trigger breakouts for some acne-prone users
Watch out for
- Oxidizes fast once opened; fridge storage keeps it usable longer
- Greasy feel turns people off
- Too weak for stubborn hyperpigmentation in some routines
