Nondrying nor irritating
I just ordered my second round of this night serum. I have dry, mature skin and because of the oil included in the serum it doesn’t dry my skin as much as a cream might. I think that this serum has lessened my fine lines and even made my skin softer. I add a little each night to the top of my hands and it also works well there without over drying or causing irritation.

No sting
This is a really nice, moisturizing retinol with the vitamin E oil it has in it and it doesn’t sing at all.

This really made my skin better.
A Korean friend with great skin recommended this to me. It has a high niacinamide content and is supposed to lighten dark spots, and I feel like my face is getting clearer. It’s fragrance-free and colorless, so it feels gentle. I’ll definitely keep using it.

Pretty good but know what to expect
This is a nice and gentle retinol, and I don’t get irritated from it.However before purchasing I’d tell people to be aware of 2 things. 1- this is an oil, which might help make it less drying but is a unique consistency for retinol in that it doesn’t absorb the way a serum normally would.2- it has a smell that I don’t enjoy. It’s a floral chemical smell bd I’d rather it have no smell or something not noticeable.If those things don’t bother you, it does do a nice job overall.

My skin feels smoother and looks more even!
I’ve been using this for a couple weeks and I’m already noticing a difference. My skin feels smoother, more firm, and just overall healthier. It’s not too harsh, especially for a 0.5% retinol, and I love that it has vitamin E and squalane to keep things balanced. Definitely part of my nighttime routine now.

Works like a charm
I love this retinol serum however be aware it’s concentration is higher than others so a little goes a long way. I never had any skin irritation or any issues when applying it in my regular skincare routine. However it’s advised not to use retinol every day or when scrubbing your face. It’s very lightweight and your skin is able to absorb it nicely so it won’t leave your face oily. I noticed that if you don’t keep it in the fridge that the color of the serum may change to a darker color due to oxidation so best to keep it in a regular fridge.

Good, but oily. Works great though. 🤷♀️
Works good, and fine lines go away after use, but…I hate the oily ness of it, I thought i wouldn’t mind, but I do, unfortunately. But if you don’t mind oilyness then thats fine. Doesn’t make skin irritated either, but thats because I’ve been using a lower level retinol for a while, DON’T USE THIS IF YOU ARE STARTING OUT WITH RETINOL!!! Use the lower percentage ones. Trust.

Staple to every facial routine 🫶🏼💋
The packaging is outstanding. This is my first purchase so I’ve only used it two days, a little bit goes a long way. I only use two drops at night. It is refreshing, moisturizing and cooling. Just make sure you keep it refrigerated. The bottle size is pretty big for retinol which is great . There is no scent which is nice. It is oily when you apply it, but it will eventually soak in. Feels great on skin can’t wait to see the results. There is a little bit of stickiness when you first apply it, but as stated before, once it’s soaked in the stickiness goes away. Very light weight and cooling to skin.

I felt my skin became softer. I have breakouts every now and then and it lifts and brighten my dark spots.

Es un aceite de textura ligera, hidrata muy bien y hace su función con el retinol, a mi piel sensible le cayó muy bien no tuve irritación ni ningún problema, lo volvería a comprar.
