Product Information

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.

Concentrated 0.3% pure retinol cream formula that promotes smooth skin texture and visibly firm skin Reference] Effects of 13-Cis-Retinoic Acid, All-Trans-Retinoic Acid, and Acitretin on the Proliferation, Lipid Synthesis and Keratin Expression of Cultured Human Sebocytes In Vitro, J Invest Dermatol. 1991, 96(5):792-7. The "building tolerance" phase can be shortened or extended depending on individual differences. Maintain this phase until no discomfort is experienced. Gradually increase frequency and areas of application. After the use of retinol, the skin may feel stingy and may show signs of reddening due to deep skin exfoliation. Irritation is a temporary and normal symptom. If irritation persists, reduce the frequency or stop the use of the product. Formulated without fragrance, parabens, sulfates, artificial colors, alcohol, mineral oil, and silicone.

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. Retinol derivatives are known to be converted to retinol by certain chemical reactions and enzyme actions and can bring an effect on the skin. However, it is a little difficult to be sure that retinol derivatives have the whole effect of retinol, as it is unclear how much can be converted to retinol in our skin by what action. One of the most well known snail based products is without a doubt the CosRx Advanced Snail 92 All In One Cream. This product was designed to utilize all of the amazing benefits of snail mucin or snail secretion filtrate, alongside a slightly more occlusive base to form a nourishing, all-year moisturizer. Like most of the products from Cosrx, the emphasis within this formula falls on the active ingredient, while keeping the rest of the formula relatively minimal for ease of use. As the name would suggest, the Advanced Snail 92 All In One Cream contains 92% snail mucin, which can help with everything from fading signs of hyperpigmentation to calming redness and reducing the appearance of fine lines and wrinkles. Snail mucin got its claim to fame because of how effectively it produces results without compromising the health and balance of your skin. Because of this, snail mucin and products that contain snail mucin are extremely well suited to almost any skin type. With that said, because this is more of a cream based formula, we’d recommend this product in particular to those with more dry or dehydrated skin types. Retinol is weak against light and heat; we recommend using it at night. If applied during the daytime, be sure to use with a SPF. (* It is recommended to apply a SPF even if not applied during the daytime. Because it can be still left on skin in the next day.

Sodium hyaluronate is the salt form of hyaluronic acid that has been shown to have better skin penetrating capabilities than hyaluronic acid alone. Similar to panthenol, sodium hyaluronate functions as a humectant by drawing moisture into the skin. Lastly, COSRX Hyaluronic Acid Intensive Cream contains emollients like caprylic/capric triglyceride, sunflower seed oil, and macadamia seed oil to help the skin feel soft and smooth. Because the concentration and formulation types of retinol are different, you can choose the product depending on the effect and after-feel that you want.As explained earlier, retinol has been used as a skincare ingredient for a long time because of its excellent skin efficacy. However, it is relatively difficult to make high retinol concentration because it is unstable against ultraviolet rays, and the higher the retinol content, the lower the stability.To solve this unstable problem, not only the development of various retinol derivatives but also the techniques for stabilizing retinol are constantly being studied. COSRX offers products for each step of your skincare routine, including cleansers, toners, serums, essences, moisturizers, and more.
