Basically, our skin produces melanin when it is damaged to protect itself from the sun (as melanin absorbs most of the UV radiation that hits your skin). Included in the ingredients list is a great mix of humectants to help keep your skin hydrated: butylene glycol, glycerin, sodium hyaluronate, and panthenol. Betaine salicylate is used as an alternative exfoliating ingredient to salicylic acid in Korean skincare products (as it is much gentler on the skin). Other beneficial ingredients: This vitamin C serum contains 72% black chokeberry (which helps to stabilize the high concentration of vitamin C). It is also a thickening agent that adds richness to cosmetic products like moisturisers, sunscreen lotions and conditioners. Simply apply as much as you feel necessary after cleansing, toning and applying any essences, serums or ampoules. Personally, my skin is currently able to tolerate the very diluted amounts of tea tree oil in this cleanser and I do make an effort to avoid any other essential oils (as the more you include in your routine, the higher the chances of skin sensitization). Slowly, you can increase the usage up to 2 to 3 times a week. Tea tree oil is an essential oil derived from the leaves of the Australian tea tree plant (Melaleuca alternifolia). In fact, it’s hydrating ability is comparable to that of aloe vera! Unlike the snail mucin cream, the star of this cream is green tea (Camellia sinensis leaf extract). So, how can vitamin C help acne-prone skin? After a year of trying different products and spending probably hundreds of hours researching for the articles I write here – I thought I’d share what I think are the 7 best COSRX products for oily acne-prone skin. Concomitant use of moisturisers could reduce the dryness while the medicines do their job, but the issue of pore clogging still stands. In fact, Korean skincare companies are not permitted to use more than 0.5% salicylic acid in their formulations (which really isn’t that effective). : If you have oily or acne-prone skin, it’s important to use a chemical exfoliator to both help get rid of dead skin cells and to help remove gunk from your pores (such as sebum mixed with bacteria and dirt). COSRX is a leading Korean skincare brand which was founded in 2014 by the experienced team working on the sister brands C20 and Ciracle. As their names suggest, the All In One Cream contains 92% snail mucin, while the essence contains 96% snail mucin. Gently massage and pat it onto your skin using your hands. In the end, I actually gave up on skincare altogether (including sunscreen) – that is until I started this website and decided to learn everything I needed to know to fix my skin. I also like to wait 20-30 minutes before proceeding with the rest of my skincare routine (as BHA is pH-dependent). Lastly, this cream also contains tea tree oil, which I mentioned earlier, has antimicrobial and anti-inflammatory properties – making it a good acne-prevention ingredient. However, there is no research to back up claims that willow bark water has exfoliating properties (as it cannot be converted to salicylic acid in the skin). However, I couldn’t find any scientific research which looks at the effects that this ingredient has on the skin. For this reason, it is popular in products meant to moisturise, soothe, and improve the texture of skin — especially in products meant to treat dry skin conditions. It is ranked very highly on the comedogenic scale, which means applying products with butyl stearate will cause pesky breakouts. It is actually the first Korean skincare brand that I turned to last year when I started looking after my skin. This cream does contain other anti-inflammatory ingredients to help soothe red and sore breakouts, including zinc oxide, betaine, and Scutellaria baicalensis root extract. It can be divided into light mineral oil and general mineral oil, while the proportion and viscosity of light mineral oil are low.
