Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Niacinamide has emerged as an all-star ingredient due to its many benefits.
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.

Gotta give credit where credit is due
WOW… lot of people ganging up on this incredibly affordable/popular serum. I understand the criticisms, but personally I don’t believe the intensity is warranted.

And because I had never used ingredients like niacinamide or zinc on my face before, of course I noticed an Show more
(Tried Jan 2021) This was actually the product that made me realize that my skin does not mix with Niacinamide (especially at high concentrations because I can usually tolerate it at %4/less or when it isn't a primary ingredient). I tested it on my wrist and a small patch on my cheek to check, and I had hives in both areas. I wouldn't want to give this a poor rating solely on the account of my Show more

TL;DR: Makes me oily and can sting a bit. Breaks me out SOMETIMES, but helped with scarring.
This is the ONLY Slurp product I don't 100% love. Sometimes it breaks me out into cysts, sometimes it doesn't. I had good results with some acne scarring on it, but it also made me feel a bit oily. It can sting on a compromised skin barrier for a split second, but it's never overly irritating. Because I Show more
UPDATE: it contains butylene glycol! If you use actives that affect your skin barrier, please restrain from using it. Also many Korean products use it. Hence layering it with other products might cause irritation!
Funny enough, that’s actually the only serum by Slurp that I do like. It absorbs fast and I do feel like my skin feels better afterwards. So I do think it helps the skin barrier. Show more
