    This is actually a wonder serum if you want to wake up glowing! I used this when I arrived overseas as my skin always plays up a few days after travelling when it’s adjusting. This definitly encouraged a 24 recovery from my breakout as normally it would take 3-4 days for my skin to recover. The texture is a bit thicker too so I didn’t need to add a moisturiser over the top before bed.

  2. Claudiaxx

    To be honest, at the beginning I was a little afraid to use this product cause I had a bad experience in the past with retinol, so I pulled off for a couple of months. Now I can’t stop to laugh at myself, this product is fantastic! It smells amazing, it feels amazing and it completely changed my life, I can’t believe that now I look this good in the morning! I scream miracle!!

    Retinol + AHAs = dream product. Surprisingly gentle on the skin, and I always woke up with my pores looking refined and my skin glowing.
