La roche posay. It’s $44 but the extra 4 is worth it. The only negative for me is the dropper, I don’t love the dispensing method, it can get messy easier than others. But I don’t mind putting up with it at all because it works so amazingly well (for me). Very noticeably brighter more even skintone after 1-2 uses. I put it on right after moisturizer which has been working really well.

Some time ago, I bought my first vitamin C serum, (la Roche posay), and it did wonders to my skin.

I use the la Roche posay one but it's a lot more money than I'd like to spend as I'm trying to save. Can I get budget recommendations in the UK?

1. Sensitive Skin Look for: Lower concentrations of Vitamin C (10% or less). Magnesium ascorbyl phosphate or sodium ascorbyl phosphate are less irritating forms of Vitamin C. Recommended Product: La Roche-Posay Pure Vitamin C Face Serum.
