Rather, COSRX skincare products contain a variety of beneficial ingredients. Let’s take a closer look at the key ingredients you’ll find in each of the best selling COSRX skincare products we introduced above.
The Cosrx Low Ph Good Morning Gel Cleanser is easily one of the most iconic products from cult favorite K-beauty brand Cosrx. Cosrx has made a huge global impact and was one of the first brands to use the principles of K-beauty to formulate products for a global market. Because of this, all of their products focus on simplicity, using only what is needed, and catering towards hydration and care rather than stripping the skin with too many actives. The Low pH Good Morning Gel Cleanser is exactly how it sounds: an energizing, purifying cleanser with a gel-like texture that has been formulated at a pH of 5. Although this isn’t mentioned as frequently, the pH of your skincare products is actually crucial in terms of formulation, as well as the amount of benefit it leaves on the skin. For example, a cleanser with a higher pH can often feel more stripping and drying on the skin, which can result in irritation in the long run. With a lower pH however, this product is able to remove dry, grime and oil from your skin without stripping it of its natural moisture.
The COSRX Snail Essence contains 96% snail mucin as the key ingredient. It has been theorized that applying snail mucin to the skin could provide skin-regenerating benefits. Many of the snail mucin benefits come from three key components: hyaluronic acid, glycolic acid, and allantoin. According to researchers at the University of Nigeria, snail mucin plays an important role in wound healing as it enhances the skin’s natural regenerative response on the formation of new tissues, probably through immune response. Due to these healing properties, snail mucin has been shown to help with acne, rosacea, scars, razor bumps, and even signs of aging.
