I'm really excited to try Dermatica and have just signed up after considering it for ages.
I've got a referral code which gives me and anyone who uses it £10 credit. I think the first box is £2.90 then £24.99 per month, although it seems that if you commit to buying several months in a row the price per month goes down.
Thanks 🙂
