Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.

Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.
This ingredient is also referred to as pro-vitamin B5 or dexpanthenol in dermatology.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

I’m on my third bottle
Want a simple, hydrating, scentless, and affordable azelaic acid serum? Look no further! Azelaic acid is well tolerated by many and for me I’ve noticed great improvements regarding redness. There was a short period of time when I cut this out of my routine, and that’s when I noticed how much it had been doing to reduce redness in my skin. This serum also contains aloe extract, panthenol, and niacinamide so it feels very soothing. Keep in mind however that there are a few different plant extracts in this as well, so if you are super extra sensitive you might react poorly to them. But personally I’ve never found them to be an issue.

I was so excited to try a product with what seemed like no comedogenic ingredients, but I suspect all the extracts broke me out pretty badly. I’m talking deep, painful cysts. I think I saw a nice effect on skin brightness, but that’s the only upside unfortunately. This also left a chalky white residue at times.

numbuzin has become one of my favorite brands along with cosrx. this is one of the two serums i own from them, this and the no.5 goodbye blemish serum.
i've only been using this since march of last year and it has been a game-changer ever since. i feel a bit dramatic when i say this, but i genuinely have seen a big difference in my skin using this compared to any other serum i've ever used. it blended in with my routine sooo unbelievably well. i don't know what type of witchcraft or sorcery is in this, but this product is a blessing and it's money VERY well-spent. beautiful bottle, it's like glass or something. it's a bit expensive, but you get so much product that'll last you way longer than a year. like i've had this since MARCH, and i still have over half the bottle left even though i use 3 drops every single night religiously.
it's hydrating, makes my skin very smooth (as it should), and has gone above and beyond in improving my skin texture. it miraculously decreased so many of the little bumps i get. it also absorbs very well under my base, literally just cleared my skin and boosted the glass skin look. i love this serum please buy it.

I had small bumps everywhere and my skin is quite sensitive but this worked very well. It made my skin almost completely smooth. The only thing it didn't fix was the stubborn closed comedones on my jaw and chin which wont go away no matter what.
