After trying various vitamin c serums, finally tried this, needless to say the brand speaks for itself. Made my face at least 2 times brighter. 

It's gentle on sensitive skin, helped with brightening acne scars.

Have been using this serum for about 2 weeks now and it's been really good so far. It's gentle on my sensitive skin but has really helped with brightening my acne scars. Have seen a difference already, so will def continue using it.

I’ve used SkinCeuticals for literally years (specifically CE ferulic in the AM and HA intensifier hyaluronic in the eve - those two products changed my life ie keeping my combination skin in check, no more bumpy texture etc I stopped constantly looking for the next best skincare product because they really work better than anything else) but recent price increases made me wonder if there are more budget friendly alternatives. I’ve tried a few but nothing compares or feels as effective so I’m back to these. They are pricey but each serum lasts me around 3 months and being at the wrong side of 30 I am yet to need Botox. I would much rather spend on preventative skincare than procedures to reverse age. Well worth the investment in my opinion

No irritation to my skin which the stronger version caused so will definitely continue to use
