    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.

    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.

    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.

    Superior Retinol Drops
    I have tried the different brands of Retinol; high end to low end in cost.This brand is wonderful, it is stabilized in Bitamin E oil. Goes on smooth and causes no redness or irritation. I use it last in my skincare routine. My skin is so smooth and wrinkle free because of my daily skincare rountinr and this product .

    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.

    Oily but great
    I do agree that it is oily, the key is not putting too much, just two drops and spread it. Although in the morning it’s gone, so that’s good. As regards the effects, I think it has made my skin better but I can’t tell honestly. I’d keep buying it!

    I use this product to even my skin tone, remove under eye bags and dark circles, remove dark spot and firm. @ applications and it was like ten years younger. Definitely worked on me.
