Overview of Cosrx  

Corsx Skincare Review

Cosrx was the result of 15 years of working in the Korean cosmetic industry. Founder Sang Hun Jun was already a distinguished entrepreneur working in the e-commerce business. However, his roots in skincare weren’t solely seen as a business venture. Jun struggled with sensitive skin ever since he was young and didn’t find much luck with many skincare products available on the market. 

Frustrated with the lack of options, Jun launched Cosrx in 2013 to develop skincare products that worked for sensitive complexions. The company’s first batch of items was formulated to target acne spots and breakouts. Soon after, Cosrx began to rapidly expand within Korea as being an affordable option for skincare products.

Considered a game-changer by various media outlets, it is one of the few Korean skincare companies that was able to make waves within the Western industry. “Our perspective on beauty has always been in touch with our customers’ lifestyles. We provide the most ideal solutions that care for skin problems,” via a statement from Corsx.  

Before we get into this Cosrx skincare review, let’s go over some initial pros and cons of the brand.


  • Variety of skincare products formulated to address any skin type or concern such as acne and minimizing pores 
  • Complete transparency on the ingredients included in the skincare formulas
  • Prices are very affordable 
  • Positive customer reviews 
  • Free shipping on orders placed in the US and Canada 


  • Some of their best selling products (which mostly include snail extract) quickly sell out 
Cosrx Skincare Review

Considered the main hub of all things good in skincare, South Korea is well known for its effective creams, moisturizers, facials, serums, and toners. As K-dramas are starting to become more mainstream within the Western media, we’ve at least agree that everyone on screen has beautiful skin.

If you’re not exactly sure of where to start, this Cosrx skincare review will provide a selection of bestsellers to help you get started. 

Cosrx Aloe Soothing Sun Serum SPF 50+ PA+++ Review 

We aren’t kids anymore. We don’t have to subject ourselves to that chalky and greasy commercial sunscreen our parents used to slather on our skin before we jumped into the pool. It’s time to grow up and pick up a bottle of the Aloe Soothing Sun Serum SPF 50+ PA+++.

Formulated with aloe arborescent leaf extract, this lightweight sunblock is a far cry from those heavy sunscreens that often left white residue as you rubbed it in. This Aloe Soothing Sun Cream helps to moisturize your skin while protecting against harmful UVA and UVB rays.

It’s also compact enough to easily fit inside your summer tote when you go to the beach. Make sure to include the Aloe Soothing Sun Serum SPF 50+ PA+++ next time you hit the pool for just $16

Cosrx BHA Blackhead Power Liquid Review 

Say bye-bye to blackheads with the BHA Blackhead Power Liquid. This specialized formula penetrates the inner layers of your skin to clean up clogged pores. It uses a chemical exfoliation technique that clears away dead skin cells, which results in your complexion having a natural glow.

This Cosrx blackhead formula is also effective at controlling excess sebum while moisturizing the skin. Containing only a minimal amount of natural ingredients, this formula has a blend of BHA and willow bark water.

If you’re adding this as an essential step in your skincare routine, this Cosrx skincare review recommends pairing it with their Low PH Good Morning Cleanser to help your face feel fresh and ready for the early day.

Stop picking your blackheads and let the BHA Blackhead Power Liquid do all the work for you for $25

Cosrx AHA 7 Whitehead Power Liquid Review 

If you’re wondering what’s the difference between whiteheads and blackheads, the answer is relatively simple. Whiteheads are usually closed pores while blackheads typically stay open. Since it’s quite hard to access whiteheads through the simple ‘pinch the popping pimple’ method, the AHA 7 Whitehead Power Liquid can do the work for you. 

Formulated with 7% glycolic acid, the AHA 7 Whitehead Power Liquid gently exfoliates your skin to help reveal a radiant and glowing complexion. It enables fast cell turnover by melting dead skin cells on the outer layers of the skin.

This hyaluronic-infused liquid hydrates your skin in the process and its key ingredient, apple fruit water, is added to brighten your overall complexion. For those that want an added boost in terms of refining their uneven skin tones, try pairing this product with the Mela 14 White Ampule.

On the other hand, if you’re just looking to address one problem at a time, go for the AHA 7 Whitehead Power Liquid first for only $22

Cosrx Real Fit Vitamin C Serum Review 

While it’s common to take vitamin C supplements to boost your health, you can also do the same for your skin by using the Real Fit Vitamin C Serum. Containing 23% of this essential vitamin, it works as a powerful antioxidant to help brighten and even your skin tone. It also gradually erases blemishes and dark spots you may have accumulated over time. 

This Cosrx vitamin c formula uses patented technology, which utilizes aronia melanocarpa fruit extract and hippophae rhamnoides extract to increase the effects of its included vitamin C. To combat dryness, 60% of propolis extract is added, as the Real Fit Vitamin C Serum protects your complexion from dehydration and stimulation. 

For something so potent, you may want to calm down your skin afterward with a product that’s designed to relax your pores. You might want to try out the Cosrx Ultimate Nourishing Rice Overnight Mask to help end your rigorous nighttime skincare routine. The Real Fit Vitamin C Serum retails at $29.

Cosrx AHA/BHA Clarifying Treatment Toner Review

Everyone should treat their skin like a delicate piece of China. Most of our complexions are quite sensitive, and from that, we should be mindful of the kind of skincare products we use. To help ‘polish’ your complexion, you may give the AHA/BHA Clarifying Treatment Toner a try.

Formulated with BHA, AHA, mineral water, and purifying botanical ingredients, it’ll help you achieve that coveted porcelain finish. This Cosrx toner is meant to soothe, refreshen, and soften the skin by removing dead skin cells and makeup residue.

To help clear your skin of any bumps before you apply this polishing toner, the Cosrx Pimple Patch can help draw out impurities to achieve that deep cleanse. You can follow this product with the Cosrx Honey Ceramide Full Moisture Cream to provide you with day-long protection. 

But if you just want to focus on freshening your skin, there’s no harm in just purchasing the AHA/BHA Clarifying Treatment Toner for only $20

Cosrx Galactomyces 95 Tone Balancing Essence Review 

Glass skin is still a rising trend within the skincare community. As seen on multiple K-pop idols such as BTS and Blackpink, you often wonder how they attain such perfect, dewy skin. While their skincare secrets are behind closed doors, we can at least simulate the effects by using the Galactomyces 95 Tone Balancing Essence.

This enhancer helps to nourish and hydrate the skin in order to result in that Instagram-worthy radiant complexion. It contains 95% galactomyces ferment filtrate, hyaluronic acid, and panthenol. Together, this trio of ingredients reinvigorates dull-looking skin.

The formula is also non-greasy, with a texture that quickly absorbs into the skin. In order to help combat those pesky blemishes and dark spots, pair this product with the Cosrx One Step Moisture Up Pad to further even out your skin tone. 

For radiant and dewy skin as the result, the Galactomyces 95 Tone Balancing Essence may be the solution that you’ve been seeking for $24

Cosrx Salicylic Acid Daily Gentle Cleanser Review 

Designed to be an effective first step to rid your pores of pollutants and dirt, the Salicylic Acid Daily Gentle Cleanser can help you remove those impurities you may have accumulated during the day. This Cosrx cleanser gently removes excess sebum while fighting against acne and blemishes.

In application, it comes out in a foamy and creamy texture that feels luxurious when lathering into your skin. The great thing about this cleanser is that it’s gentle enough for sensitive skin types, as it doesn’t strip your face away from natural oils.

To combat those pre-existing acne spots, the Acne Pimple Patch is designed to directly target those troublesome areas. For those that need that element of hydration, you can add the Cosrx Balancium Comfort Ceramide Cream right after.
