An amazing serum. From the very first day the results are visible. In the morning my skin is so bright and soft. Certainly, as time goes by, the results will be even more evident, especially in wrinkle reduction. I highly recommend it.

this product is amazing. visible differerence to my skin within a short time of use. not irritating to the skin and feels very nice. Definitely worth the high price.

I just used this for 2 weeks since I bought it (once a week). The next morning after I used it at least a pimple popped out. I know it’s working, but the acne scarring after is another thing I have to deal with. I would prefer a gentler Retinol.

This serum has been amazing so far. My skin has not been irritated at all (though the first time I used it I was a little flushed but in the morning there was no redness). I have also noticed improvements in my skin already!

I used to bring PTR products home from the US every time I was there and I am so delighted that this beautifully made skincare is finally available at Cult Beauty.

This is almost a dry oil, sinks right into the skin, and has an amazing slip. You need so little - and that's one thing that may make it difficult to apply. I have to use the dropper pretty close to my skin and work in quickly, it will run right through your fingers! Was a nice graduation from my Sunday Riley retinol serum, which I currently alternate with using this twice a week. Makes my skin brighter but hasn't caused any flaking or reaction. Think the bottle will last me ages.

My skin has noticeably been better since the first use, my skin is exceptionally brighter and smoother. I love the texture of the serum too, it caused no irritation whatsoever I was able to use this nightly from the get go.

I’ve used almost 1/3 so far, and I really like it. I replaced my Good Genes with it (night time), and all those small irritation pimples that appear during the day are gone by morning. Oil-like texture is really pleasant, and I have not experienced any irritation (while using it every night for almost a month). Texture of my skin seems better and some old pigmentation is healing pretty nicely!

Unlike other brands, this brand has not many ingredients, but it still works without causing any irritation or dryness. I noticed my skin is brighter in the mornings. My blemished seemed lighter too (if only this can be used in the mornings - to help with my pores and blemishes).

The product itself is really good. It absorbs into your skin and has no smell to it. A really lightweight formula. For me, I don't use this product daily as I have sensitive skin and prefer to use this a few times a week and it has made my skin feel soft and look brighter. It doesn't make me break out and I am happy with the results so far.
