Are you looking for a serum that is designed to clear up your skin? COSRX AC Collection Blemish Spot Clearing Serum was created by South Korea’s leading manufacturer of skincare products. COSRX has released several popular skin care products that go beyond your expectations. This product is no different. It speaks for itself through its ingredients and reviews. There are many things to consider when searching for a good product, but this one stands out above the rest. You need to read my review on the product before making a purchase or anything else while using COSRX AC Collection Blemish Spot Clearing Serum.

About the brand

One of the most popular Korean skincare products right now is Cosrx, which focuses on creating high-performance cosmetics that are both practical and safe to use on everyday skin concerns.

The brand name is made out of the words “Cosmetics” and “RX.” In the pharmaceutical sector, RX is frequently used as a synonym for “prescription.” This illustrates the brand’s mission, which combines science with beauty!

For ten years, the creative organization has actively investigated the issues related to diverse skin kinds. They subsequently created skincare solutions that are suitable for all skin types. Their goods contain only the most fundamental components, resulting in minimal irritability and maximum efficacy.

Since 2015, Cosrx has been creating clean beauty products free of 14 different dangerous chemicals, including mineral oil, sulfates, and parabens.

According to the product description, the COSRX AC collection blemish spot clearing serum is a “complete solution serum that eliminates all signs of acne, including redness, black spots, and scars.” In addition to being paraben- and cruelty-free, it claims to relax, soothe, brighten, and strengthen skin (amongst other things). Something like this is truly a dream come true for someone like myself who battles with monthly breakouts.

The following are the three purposes of this serum:

  • Calming: For active inflammatory acne and red spots
  • Clearing: For after-breakouts and dark spots
  • Recovery: For uneven skin texture and scars

The COSRX AC Collection Blemish Spot Clearing Serum has a s very lightweight composition that caught my attention right away. My skin practically has the texture of water. It dries rapidly after application and is neither sticky nor greasy.

Due to the formula’s sheer texture, which makes it comfortable to apply during the day under makeup, it leaves my face feeling soft and smooth and blends nicely with other skincare products.

COSRX AC collection blemish spot clearing serum is the ideal substitute for benzoyl peroxide and salicylic acid products for my slightly sensitive skin because I frequently experience problems with those ingredients. It eased and regulated the redness and breakouts on my skin instead of irritating it in the least.

For acne-prone skin, this lotion has some amazing components. Niacinamide, tea tree oil, and propolis extract are all well known for their ability to treat acne.
I adore that some of the active ingredients come from Centella Asiatica. It is a traditional Chinese and Ayurvedic medical staple that dates back thousands of years.

Together, the three Centella-derived ingredients in this product—asiaticoside, Asiatic acid, and madecassic acid—calm acne and post-acne redness.
The fact that this serum doesn’t contain any abrasive or drying acne treatments that can damage your skin’s fragile barrier is, in my opinion, one of its best features.

To keep out external stressors like bacteria and pollution, which can exacerbate acne and breakouts, and to lock in moisture, it is crucial to have a strong skin barrier.
I am quite happy with the serum overall.

How to use: COSRX AC collection blemish spot clearing serum

Just use two to three drops for your entire face, keeping your eyes well away. You don’t have to pay attention to how much you use; I normally use a dropper that is only half full and places more drops in strategic locations.

One thing to keep in mind is to avoid letting the dropper on any product with a dropper touch your face. It’s not a good idea because the droppers could take up microorganisms from your face. You can use it on your entire face or just your spots.

I think the COSRX AC collection blemish spot clearing serum bottle lasted approximately a month with regular usage and about two months with less frequent use.
