Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
- It has mild preservative properties.
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
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.

Gently Exfoliates
I decided to try a leave-on exfoliator rather than an exfoliating cleanser because I noticed I kept getting irritation from exfoliating cleansers. This Cosrx one is really gentle and pleasant. It takes a few minutes for it to absorb into my skin, but afterwards I get very little irritation and my skin texture and pore appearance have definitely improved.
My favourite COSRX product. Pores appear smaller after a few hours. Was not expecting sebaceous filaments to disappear. I usually use one pump of liquid and put it directly on my T-zone and leave it to do its magic for about a few hours before applying moisturiser. (Putting moisturiser right after reduces its effectiveness from my personal experience.)
