WHAT PEOPLE SAY

“I went through a similar trial and believed that vitamin C wasn't doing much of anything for my skin because I still experienced discoloration and some (admittedly mild) melasma on my forehead. I used it for about two years straight and figured I was wasting money and gave up. But giving up was what made me notice what a difference it was making for me. Once it had been fully out of my routine for a while, my skin just looked... dull. It wasn't dry or anything, but it just lost some of its youthful brightness. The average person around me might not notice, but I sure did.”
U/BEEEEDEEEE ↗“Alright, so the first problem is no patch testing. The second problem is you went from no vit c serum to vit c serum every day. Vit c, especially if it's in the ascorbic acid form, is a mild exfoliant and should be treated as such. Gotta work up to using on the daily if you're super fair/ sensitive. As far as getting your skin back to normal I'd revert back to what you were doing before you tried the serum because you're skin was b-e-a-utiful. And some good physical spf to protect your skin while it heals.”
U/JUSTHEREFORTHEAWWW ↗“Vitamin C for dark spots is a myth to me. I think it depends on how your skin tone gets uneven. For general protection against environmental factors, Vitamic C works well. I haven't used Dr. Dennis Gross Vitamin C Serum but their masks gives me a glow I think you're supposed to get with Vitamin C but it's temporary. My problem with Vitamin C is it's so unstable and sensitive to the environmental factors like light, air, temperature, etc. that you're more likely to experience irritation or reduced effectiveness before finally finding something that works.”

Add context that might help others — skin type, conditions like PCOS, what you'd tried before. The more specific, the more useful.
