Good Molecules have been around for a while now. The first charter about the brand was from the 2019 Beautylish Lucky boxes when they included a few products in the boxes. The brand promises low-cost skincare with highly effective products. I’ve been interested in the brand for a while and I have picked up a few of their products for testing.
Good Molecules is currently not available in the UK but you can get them via Beautylish. The Daily Brightening Serum is formulated with beta Arbutin and hyaluronic acid to gently brighten the skin and provide hydration.
Experience
I was using this every morning after toning and before my AM moisturiser and SPF. This is a very lightweight serum and layers very well with other products without pilling. I experienced no irritation from this. It comes in a lux glass bottle with a dropper (that works!) and in the standard 30ml. This serum caught my eye because I am always looking for ingredients and products that target pigmentation.
This serum has Beta Arbutin as its main ingredient. Arbutin is known for its brightening properties and its ability to inhibit excess melanin production. I have used Arbutin before but in the Alpha Arbutin form from the ordinary and I had no luck with that. I wrote off the ingredient completely but wanted to try this serum as it’s the beta form (although the alpha form is supposedly more effective). This serum also has hyaluronic acid for hydration.
I really like this serum. It’s lightweight and absorbs easily without leaving a ‘film’ on the skin and no stickiness. I find it provides some hydration and layers very well with other products. I never experienced pilling. In terms of gently brightening the skin, I began to see results in the 3rd to 4th week of using the serum: my skin generally looked healthier and some hyperpigmented spots seemed lighter but then I run out of it a week later. I was happy with this because although the results were slow I experienced some benefits compared to using alpha Arbutin
Verdict
Good Molecules say this serum gently brightening the skin tone and it definitely does. Gently! You definitely have to stick to using it. It provides hydration and brightening and it was very easy to add to a routine. The serum can be used day and night but I preferred it for daytime use. I wish I had another bottle to start using immediately after I finished it because I would have had better results.
Will I repurchase: yes because I really like it and it works!
Good Molecules Daily Brightening Serum is $9 on Beautylish. You can also get it in the Correct Brighten & Boost set for $29 which also has 2 two products. I got the set (it works out to be the same price if you bought those two products separately). This is the first product I have finished from the brand and I am impressed (I’ve been using the vitamin C booster powder intermittently! I still have a few products to use and I will be looking out for any new products on Beautylish
