Almost empty? Formulated for regular retinoid users, this is a refill of our intermediate-level vitamin A serum that targets multiple signs of ageing, including fine lines and wrinkles, dullness, uneven skin tone, texture and breakouts.

A repurchase for me. After a hiatus I opted to get the retinoid 1 as a restart and looking forward to upgrading to 2 soon. Also glad to see there is a 3 as well!

I have bought this refill number 2 alongside number 3 to use afterwards! My skin is left clearer and glowing and I would 100 per cent recommend purchasing as you will not regret it! Brilliant product

Love the feeling of this on my skin! I've used Ret 1 and have upped to Ret 2 - no real skin concerns, so I'll stick with Ret 2! A little goes a long way and I use it about 3 times per week as part of my a. m. routine, alternating with the Gentle Acid.
