I use this in conjunction to my hyaluronic acid and it’s a nice boost to keep my skin from losing moisture. I use it daily

This moisturizes the skin much better than hyaluronic acid, for example. It has been saving my skin this winter, and I especially love it as a makeup base.

I love to add the serum to my foundation to sheer it out and add hydration. Also works great on no makeup days when pumped in with moisturizer. Skin type: Dry Product benefit: Moisturizing

It acts like a boost and seal to my routine with base layer of hyaluronic acid. It’s not as watery however, and has a oilier/more solid gel texture

I love adding this to my foundation to make it extra moisturising and dewy. Lovely on its own too.

The product is great, it significantly helps to keep my very dry skin well moisturized throughout the day. The problem is with the container that holds this great product. The pump fails to to work and in order to access the product I had to forcefully break off the top and pull the pump out. I ordered two of these products as buy one get one free and both bottles had bad pumps. I gave this three stars because the formula inside is wonderful, but the pump is garbage and that’s where it is right now in the garbage I would easily order this again, but I won’t because of the pump and having to break the container in order to access the product.

I was thinking for a while to try this serum and I wasn't disappointed. It's very easy to put on the skin and leaves it looking nice and feeling so silky.

This serum (at least for me or the batch I received) smells really bad at first, like a really strong alcohol or gasoline type smell, but after it gets rubbed in, the smell completely goes away. It feels nice on the skin after it's worked in - very soft and hydrating feeling, not at all sticky - but not sure if I will keep using it because the smell is so strong and unpleasant at first.

It moisturizes and nonirrritates my sensitive skin. Iam using it almost every night, and see the result already.

Moisturizing and non irritating on my very, very sensitive skin. I use this every night under moisturizer.

This completely changed my makeup game. I have to use a lot of powder so my skin always looked dry and the maekup cracked after many hours, but using this before and after makeup has both made it look and feel amazing. My favorite product by them.

Just got the serum in the mail and it doesn’t come out of the pump. Priming the pump doesn’t work. I’ve been trying for 15 minutes and nothing.

If your skin still feels tight and dry even though you’re using hyaluronic acid, this is why I switched to polyglutamic acid instead. Polyglutamic acid actually helps hold onto moisture so your skin stays hydrated longer instead of feeling dry again an hour later, and this one from The Inkey List is super affordable and layers perfectly under makeup or moisturizer.  @The INKEY List #TikTokShopCreatorPicks #TikTokShop #DrySkinRoutine #HydratingSkincare #AffordableSkincare
