Can medik8 vitamin C do this?

[FlorencePennnywell]

I started using a Medik8 vitamin C serum recently. Within a few days my entire face was covered in a pale bumpy rash which feels rough to the touch and is a little bit sore but doesn't look sore if you see what I mean. The rash is raised with tiny bumps

The only thing I've really done differently recently is use this vitamin C serum - and I used it every morning for about 4/5 days on the trot. Was this too much maybe?

Which one are you using? There's different types. I have extremely sensitive skin and use the c-tetra luxe daily and it suits my skin. Perhaps it doesn't suit yours. I would stop using it for few days and see if it clears up. If that's the only change then it's likely to be that.
