I have a couple of stubborn dark spots from an old breakout that just would not fade no matter how many "brightening" moisturizers I tried, and at some point I realized I was basically throwing money at the problem without actually understanding the ingredients. My sister, who's way more into skincare routines than I am, told me flat out that moisturizers alone weren't going to cut it and that I needed an actual concentrated serum. I compared two vitamin C options based on percentage and reviews, went with this Paula's Choice one since it kept coming up as effective without being overly harsh, and started seeing the spots noticeably lighten after about six weeks of consistent morning use. It's now a permanent fixture in my routine, right after cleansing and before sunscreen.

Buying Guide

- Patch test first. Apply a small amount to your inner arm for 24 hours before using on your face.
- Pair with sunscreen. Vitamin C serums work best alongside daily SPF protection.
