Lovely - no irritation!
This is my first product from Medik8 and I really love it - it doesn't cause any stinging or burning to my eyes and I find a lot of eye creams/serums do, so that's been great. I also haven't experienced any peeling or flakiness from the retinol so that's also excellent. I do wish it was larger as another reviewer mentioned it is being used up super fast! Would still repurchase this tho
