High quality incredible serum
I LOVE this serum! I really feel like it hydrates my skin and it’s non greasy, easy to apply and no smells. For the price it us really good value for the money. Easily comparable to expensive products. It’s really easy for my skin to absorb and it’s lightweight.

Great for dry skin
Looovvveee this stuff. At first it feels a little sticky but once your skin absorbs it, it feels so hydrated. I was worried about using this because i have dry and sensitive skin but if anything it made my skin calm down. I haven’t broken out and i’ve been using it for a while, makes my skin so glowy too.

Best cleanser I've ever used.
This is easily and by far the best cleanser I've ever used. I have sensitive, oily, dehydrated and aging skin. I wear mineral sunscreen, primer, and bb cream cream daily AND I smoke, so there's a lot for a cleanser to fully remove. This does, cotton ball with toner tells me so. This cleanser is unscented, foams beautifully, and takes everything off including mascara without a pre-cleanse ( makeup remover oils or balms break me out, every time). It is gentle and doesn't strip my skin. It leaves my face actually clean and comfortable. My serums sink in quickly after use, and my skin is noticeably less greasy during the day because it's balanced. Considering that this cleanser is also affordable and a little goes a long way, I'd say it's close to perfect. Love it.

Gentle, hydrating, and perfect for sensitive skin
I’ve been impressed with this cleanser. It creates a soft, rich foam that feels great on the skin, not stripping at all. What I love most is how gentle it is. I used it consistently after a laser treatment, when my skin was especially sensitive, and it never caused any stinging, tightness, or dryness. It left my skin feeling clean, calm, and hydrated every time. The ingredient list is solid, featuring hyaluronic acid, squalane, and ceramides, which suggests it helps maintain my skin barrier rather than breaking it down, unlike some other foaming cleansers. It’s also pH-balanced, which I think makes a big difference if you’re using active treatments or have easily irritated skin. I’ve tried many cleansers over the years, and this is one I can see myself coming back to. Definitely planning to repurchase once I finish the bottle. A great daily cleanser for those seeking a soothing yet effective product.
