Just started using this
I have just started using this do it is a bit early to review any results as it should be around 6-8 weeks before any noticeable improvement. My skin feels soft and I have not had any negative reaction.

Too strong
It was a bit to strong when I decided to add vit C in my routine. For the beginners I recommend to find a lower strength vit C. For my rosacea/flashing skin was too strong.

Worth it
I did think a lot to buy or not to buy, and I did. It’s a great serum, skin is silky and smooth after applying, not greasy or oily, just leave to absorb a bit before applying a moisturiser
