Less is more when applying 😻
After some thought, I decided to switch to a niacinamide-based serum with Ecotin. I had been using Seoul Cuticles’ day and night snail mucin serum, which did brighten my complexion, but I didn’t feel it was doing much for my pores.Good Molecules’ serum contains 5% niacinamide along with 0.50% Ecotin and 0.50% Betaine. The Betaine really impressed me for hydration – I noticed a big improvement compared to my previous serums. Ecotin, on the other hand, helps shield the skin from environmental stressors and feels incredibly soothing. I found it particularly comforting when applied about ten minutes after my Tretinoin ointment.The texture is slightly sticky at first, but not in a gluey way. It blends in effortlessly and dries down without leaving any greasy or tacky finish. A little definitely goes a long way. The scent isn’t overpowering either!Overall, I’m genuinely pleased I made the switch. This serum has earned a permanent place in my routine, and I’ll definitely be restocking. 🥹

Great Serum
This is a great serum! It has 5% niacinamide and perfect for sensitive skin that can’t tolerate higher percentages. The addition of the hyaluronic acid and ectoin make this serum very hydrating as well. It has been very helpful for my skin’s barrier and helps with PIE and PIH. I have sensitive skin with rosacea and this serum hasn’t caused any irritation or rash. It is fragrance free and has no scent. A little goes a long way, so I think the bottle should last a decent amount of time.

Calming, Clearing skin, and Affordable!
I’ve been using the Good Molecules Niacinamide Serum with Ectoin for a few weeks now, and my skin already looks more even and feels calmer. It absorbs quickly with no sticky residue, and layers well under other products. Adding ectoin makes it feel soothing, especially after sun exposure or breakouts. I’ve noticed fewer blemishes and less redness overall. Great quality, and the price is a steal compared to similar products from other brands!

Great Serum!
Unlike other niacinamide serums I have tried in the past this one is gentle—I have never had any reaction or breakouts! It is not oily at all and has no smell. It takes about a month the see results but a gentle serum that is worth the wait.

The Budget Secret for Luminous Skin (Honest Review
Wow, for such an affordable product, it’s marvelous! I use it as a prep before makeup, after sunscreen, and it leaves a beautiful glow on the skin. I don’t feel a huge difference in my pores, but it definitely leaves that luminosity on the skin.

Simple, yet effective
This product works well for my sensitive skin! After having terrible luck with The Ordinary, I decided to give this brand a try. Love the ease of application and the texture of the serum. The serum does not dry sticky or tacky. It doesn’t burn my skin and it leaves my skin feeling smooth! Great quality for the price.

Breathes life back into my skin!
This is my all-time favorite skincare product I’ve ever used. The first time I used it I saw a difference in my skin. The best way I can describe the effects is that it revitalizes the skin, as in my facial skin looked quite dull prior to use but after a few drops my skin looked fresh.The dropper application is great because it keeps bacteria out of the bottle (make sure you don’t touch your face with the dropper tip!). I typically use 3 drops on my freshly washed face before any other products. Because you only need a few drops, this product lasts a long time! And at $8? It’s super affordable. I can’t rave enough about this serum.I’ve been recommending it to all my friends and family. My sister tried some of mine and she loved it. My mom just purchased herself a bottle as well.Why did you pick this product vs others?:I chose this product for the price point after being recommended Niacinamide 5% Serum from this brand (Good Molecules) or The Ordinary.
