Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Smoothing
Loved

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. For so many people this was the start of their skincare journey; it certainly was mine! And because I had never used ingredients like niacinamide or zinc on my face before, of course I noticed an incredible improvement in regards to my acne and skin tone evenness. This is a good serum to start with. No, you don’t need 10% strength (2%-5% works well) and for some that 10% can be irritating. However most people can handle 10% just fine so it’s not something many need worry about. The formulation isn’t elegant and sometimes it gets frothy or pills when you try to rub this in— BUT this is $6! You can’t really beat The Ordinary’s prices, and for some people $6 is all they can afford to spend on skincare so this is a good affordable option.
If you already have effective products with niacinamide in your routine, you do not need to add this in because it won’t really do anything for you. But if you’re just washing your face with something like dish soap then of course this will make an incredible difference. You’ll probably move on from it eventually, but it’s an effective place to start. Wishing everyone the best on their skincare journey. <3

(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 allergic reaction as I'm sure it works for many others.
