So I used a retinol cream a few weeks ago for the first time. Thin layer under eyes. Nothing happened and a few days later I used my toner (didn’t realise it had retinol in it too) and it burnt and I then had red rings around my eyes! Avoided since and eventually it settled but it left a red dot like a bruise under my eye. This then went and I forgot about it’s not used the retinol cream again but started back with my toner and the red dot/ bruise has reappeared! Not sure what it is and why it has come back? Any ideas?!
