COSRX Rx Line - Everything you need to know about this powerhouse line up

Here is everything you need to know about COSRX's latest lineup: The Rx line!

Based on research, the Rx line features highly concentrated skincare products using the optimal combination of active ingredients to target commonly experienced skin concerns such as hyperpigmentation, melasma, fine lines and wrinkles.

Let's take a look at the Rx line and find out which product is right for you.

Vitamin C

COSRX Rx line features two Vitamin C serums (both contains pure Vitamin C): The Vitamin C 13 Serum and The Vitamin C 23 Serum which you have probably seen trending on social media.

Vitamin C benefits focus on improving uneven skin tone. The Vitamin C 13 Serum contains 13% Vitamin C working to fade dark spots, scars and hyperpigmentation. To enhance the effects of Vitamin C, this formula is infused with a Vitamin E derivative that acts as an anti-oxidant. The combination of Vitamin C and Vitamin E means that these two ingredients work in synergy to provide maximum protection against environmental damage, helping to prevent premature ageing - reducing fine lines and maintaining a more youthful appearance.

For beginners and for those with sensitive skin, this 13% serum is the best one to start out with as this brightening formula is also infused with Sodium Hyaluronate to make sure the skin stays hydrated while Allantoin - a soothing ingredient alleviates skin irritation delivering a calming effect.

For more advanced users or for those looking for a more concentrated Vitamin C serum, look no further than the COSRX - The Vitamin C 23 Serum which is formulated with 23% Vitamin C, Vitamin E and Hyaluronic Acid to improve dull skin, fade scars, dark spots and pigmentation. This Vitamin C serum also targets signs of ageing by plumping and firming skin while reducing fine lines and wrinkles.

Hyaluronic Acid

Experiencing dry, dehydrated and/or flaky skin? Why not give the Hyaluronic Acid 3 Serum from COSRX a go? A highly concentrated 3% Hyaluronic Acid serum that hydrates, plumps, soothes as well as supports the skin's moisture barrier. It works to retain moisture, plump skin and deliver a hydrated glow so you can say goodbye to those pesky dry patches and dull, dehydrated complexion. 


Struggling to fade dark spots and post acne scars? COSRX The Niacinamide 15 Serum is a highly concentrated serum that combines the maximum concentration of 15% niacinamide with optimal ratios of synergistic ingredients for total acne and pigmenation control.

Niacinamide is known to provide acne care by controlling sebum production, soothing acne inflammation and diminishing post acne scars. N-Acetylglucosamine(NAG) works in synergy with Niacinamide so that this dark spot serum effectively fades hyperpigmentation and improves activated sebaceous glands, blackheads, whiteheads, melasma and blemishes.


If there's one powerhouse ingredient that does it all - it is this! Retinol is a form of Vitamin A that targets concerns ranging from acne breakouts, pigmentation and anti-ageing as it works to increase skin cell turnover. COSRX has 2 retinol products in the Rx line.

COSRX The Retinol 0.1 Cream is an irritation-reduced retinol cream created with the optimal ratio of key ingredients for first-time retinol users. This cream contains 0.1% retinol and is perfect for those just starting to notice the appearance of fine lines caused by dry skin. This cream prevents and correct early signs of ageing before they set in. 

This COSRX retinol cream also improves the appearance of fine lines, wrinkles, boosts the skin's elasticity, smooths skin texture whilst moisturising and protecting the skin as well as brightening the overall skin tone and fading scars.  

For more advanced users, COSRX The Retinol 0.5 Oil is formulated using 0.5% stabilised, pure retinol for powerful anti-ageing care. This retinol oil is best for skin accustomed to retinol but still experiencing progressive signs of ageing such as fine lines, wrinkles, loss of elasticity and dryness.

This retinol oil formula harnesses the nourishing properties of plant-derived squalane to help protect against dryness, while Vitamin A supports collagen production and skin cell turnover and vitamin E reduces visible signs of ageing and skin damage.
