Isntree Hyper Retinol Ex 1.0 Serum 20ml

I waited until almost an empty bottle before I wrote a review.
This retinol serum is made with bakuchiol and retinol. The bright yellow color is from the bakuchiol. This serum is very thick- more a cream really and the serum stings a little but the results speak for themselves. I put this on at night and followed up with a moisturizer.
My only minus is that the packaging would have worked better in a tube rather than the dropper as towards the bottom of the bottle I struggled to get the serum out.
A month of regular use and fine lines were reduced, along with faded dark spots. I have mature acne prone skin with olive undertones and this worked really well for me.

Really thick and pretty strong for a retinol. I like to use this two days on with a 3 day break, to avoid irritation.
