Ingredients Side-by-side
Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

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.

Extracts of licorice have demonstrated to have antibacterial, anti‐inflammatory, antiviral, antioxidant properties.
One component, glabridin, has extra potent antioxidant and soothing properties. It has also been found to block pigmentation from UVB rays in guinea pigs.
Licorice Root also contains a flavonoid. Flavonoids are a natural substance from in plants. Flavonoids also have antioxidant properties.
Another component, glycyrrhizin, has been found to have anti-inflammatory and antimicrobial benefits. This may make licorice root extract effective at treating acne. However, more research is needed to support this.
Liquiritin is one of the flavone compounds found in licorice. It has been found to help lighten skin by preventing tyrosinase from reacting with tyrosine. When the two react, protein is converted to melanin. Melanin is the substance in your body that gives your features pigmentation.
Licorice root is native to Southern Europe and Asia. It has been used in traditional Chinese medicine to help with respiratory issues.

Carbomer is commonly found in many types of cosmetics products. It is found to be safe in concentrations up to 15%. However, a high amount of carbomer can cause pilling or balling up of products. Most products contain 1% of less of carbomer.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:

The only retinol my partner's skin can tolerate.
Their skin is extremely reactive and sensitive but this retinol has worked great.
I also use it every other day because I alternate between this retinol and A313.
It works great and is gentle enough to allow me to build tolerance without purging effects (at least on my skin and my partner's)

I was not very knowledgable about skincare when I first tried this product, so I can't fault it for that, but I have to say it was extremely irritating for me.
If you're new to skincare and are looking for something for acne, I do not think you should start with this.
I'm honestly not sure what is in this that is supposed to treat acne besides Niacinamide, which I've come to suspect my skin may not like in any amount anyway - I think it irritates me and causes flakiness.
And on top of the potentially irritating niacinamide, it has ascorbic acid, which is crazy given that Numbuzin is not marketing this as a vitamin C serum whatsoever. Vitamin C is a good ingredient for some people, but it doesn't treat acne, and ascorbic acid is the most irritating form of it. Why is it in here??
AND it has three essential oils in it! For what? Again, essential oils are irritants and, as far as I know do not treat acne.
So, why would you put highly irritating ingredients that do not treat acne in a product that is marketed as an acne treatment? If anything, those will only worsen acne, as irritated skin tends to be more acne prone.
I don't know, maybe I'm missing something, given that this product is so highly rated otherwise, but I just wouldn't recommend it to anyone, personally.
