Community Rating: Mixed

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

What it does: Smoothing
Community Rating: 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.

Was surprised
I don't have very bad dark circles under my eyes but I have been using this daily. At first I didn't see anything beneficial about it. But I do think it is quite moisturizing as an eye moisturizer and it doesn't sting. One day I was doing my usual skincare and to my horror I saw obvious under eye dark circles. I applied this, and within a few minutes, the dark circles went away! It becomes my HG from now onwards.

(Using Since Jan 2023) This has been one of the better eye creams I have used and is still a part of my routine due to its other benefits, but I am still on the lookout for an eye cream that will continually brighten my dark circles as that is a key concern for me. I find that it is on the cheaper end for an eye cream (It's honestly the most expensive product in my entire routine). Haven't experienced any irritation using this product so it works great on sensitive skin. I noticed a slight improvement for brightening in the earlier weeks of use but not much after going through the second bottle or so. I will say that this has been great for hydrating my undereye area and depuffing (I usually keep this in a mini-fridge and pair with an overnight reusable eye mask).
