Best vitamin c serum please

[dahabaya]

I tried the Peter Thomas Roth but it “crumbles” under moisturizer and sunscreen. A Sephora specialist recommended Murad advance active radiance serum but haven’t tried it yet. Any suggestions?

Vitamin c is a very unstable active ingredient. I would avoid buying it from Sephora or Ulta or any other makeup counter. I would go with medical grade options like ZO skincare health or Skinceuticals. If not stable, vitamin c can actually do more damage such as becoming a free radical under the dermis and causing irritation or aging.

@dahabaya I also really enjoy the Tatcha night serum, and for day time I have used Ole Henriksen Truth Serum for a long time. I like the fresh citrus scent in the Ole, makes getting ready in the morning a lot easier!

@dahabaya you can try DRUNK ELEPHANT - C-Firma™ Vitamin C Day Serum, TATCHA - Violet-C Brightening Serum 20% Vitamin C + 10% AHA or KORA ORGANICS - Noni Bright Vitamin C Serum

I would try samples

I second the DE C-Firma. I love that stuff.
