Mind blowing results
I got a sample sachet with my purchase, I didnt know this is such an effective serum, I could see the results on the first night I applied, in the morning my skin was clearer, plump and fresh this also helped in healing my pimples. I want to purchase a full size bottle now.
Report this reviewNice but overpriced
I got a big sample of this in one of the goody bags, which lasted me about 3 weeks - I used it morning and night most days. I wasn't using a serum before, and I've definitely seen an improvement in my skin since using this - more plumpness and less redness especially. However, I suspect I could have got these results at a much, much lower price.
Report this reviewAmazing for broken skin
Used it every time when I have irritations or scars on my skin and this serum will calm my skin down overnight. A must-have post-treatment.
Report this reviewAverage
I chose this product as my "sample" twice from Cult Beauty to get a real feel for it. It's obviously ridiculously expensive so I was expecting a lot. I have no huge issues with my skin, just blackheads and pores, so I've been putting it on my nose, cheeks, chin and forehead mainly where my blackheads are to see if it would minimise or diminish them and I haven't seen any results so far. One sample lasted me a week as I used it super sparingly and I'm now onto the second, so you do get a nice amount in the sample. I understand perhaps you wouldn't see results this fast, but I haven't noticed anything drastic, which you'd expect for the price. I did think one morning my pores were a little smaller but looking back now.. they look the same. Think I was just trying to look for something as I had high hopes! Buy it if you have the money spare but I assume you could find better. I'm 24, and my skin is normal/combination.
Report this reviewGreat product
I received this in the summer goody bag and thought it might be another fad product but boy was I wrong! I use this daily on top of my strong retinol at night and it’s the only thing that stops that dreaded retinol peel effect. The trial size has lasted ages as you only need a small amount but I will be purchasing the full size when It runs out. 4 out of 5 stars due to the ridiculously expensive price tag but I really couldn’t be without it!
Report this reviewFeels like cologne
It works great but the scent is overpowering in my opinion. Feels like i’ve just put straight up cologne on my face and makes me slightly concerned about irritation.
Report this reviewJust ok...
I absolutely hated the rose gold face mask as well as the black diamond eye mask from this brand. Especially due to the incredible amount of perfume in it. So was very sceptical when trying this. Turns out it‘s half that bad. Perfume is ok, at least it is not overpowering and does not linger. I actually liked the lightweight consistency and found it sinked in right away. I used it for 3 weeks without seeing any results. So probably not quite for me, but at least it did not cause any irritation nor migraines (like the two masks from the same brand did).
Report this reviewOutstanding Result
I found this serum heals and evens out my acne scars. Skin is very refined, soft and firm. Pricey, but the result is extravagant!!!
Report this reviewNot for sensitive skin
It has a nice, light texture and absorbs quickly but got horrible breakouts after using it so if you have sensitive skin, this is not your product.
Report this reviewGreat product
This product reached me through the Summer Goody Bag. I was intrigued to test it, as I saw many good reviews for 111Skin. The skin feels plumped and hydrated after using it, it absorbs really fast. However, the only negative is the price point. Wayyy too expensive for an average person’s budget.
