Very good, helps with pcos acne and dark spots
I have pcos, so my acne and dark marks from acne can get pretty severe, in one use there was a visible change. It doesn't have an intense fragrance. It doesn't make my skin feel heavy, sticky, or greasy. My skin feels healthier and holds moisture better. It has a good amount of product in each container. I'd say its definitely got a good amount of value for the money.

Good Molecule
I tried their one product once and it was very good, so when I saw the set range - I definitely had to get it. A great set introduction to this line of brand. It’s light, it works and the price bracket is friendly on your wallet.

Hydrated & Bright: My Good Molecules Review
I recently overhauled my daily skincare routine with a full lineup from Good Molecules, and the results have been nothing short of wonderful. I've been consistently using their cleanser, toner, hyaluronic acid, Wakeup Eye Gel, and daily moisturizer, and my face has completely transformed. Overall, my skin feels incredibly soft, looks noticeably brighter, and stays perfectly moisturized all day long.

Good combo for the price
I have eczema which causes me to have very dry skin. I have been using this for 3 weeks and only had 1 breakout which I don’t think correlated. I did go in with extra moisturizer on top of the moisturizer that is included.
