I signed up to this on a free trial about a year ago and am so pleased I did as it is genuinely improving my skin.
What you receive is a dermatologist prescribed skincare tube that is specially formulated for you according to your skin needs. I have tretinoin , azelaic acid and niacinamide as I need anti ageing ingredients .
You send a pic of your face to them and fill in a questionnaire to establish your needs. They also prescribe antibiotic preparations for acne etc.
This is a subscription service but you can cancel after a month if you don’t get on with it but honestly this is really good stuff and much stronger than shop bought preparations as you are under a derm.
My referral is JESSE5FYH - I get a tenner off and you get a month free.
