COSRX products – What is each COSRX product for? The complete selection guide

Sep 7, 2026

By K-Beauty For You

It’s easy to get lost among COSRX products: Snail Mucin, BHA, Vitamin C, Propolis, peptides, PDRN—and that’s without even mentioning facial cleansers, toners, essences, and moisturizers.

But which COSRX product should you choose if you want to address breakouts, blackheads, dehydration, dull skin, or the first signs of aging?

The good news is that you don’t have to try the entire COSRX range. The first step in choosing the right product is to determine which skin concern you’re looking for a solution to.

In this guide, we’ll show you what each COSRX product is for, which skin type it suits, and how you can incorporate it into your routine.

Which COSRX product is right for you?

If you want to quickly find the right product, start here:

More hydrated, more comfortable-feeling skin → Snail Mucin
You want to care for dry, dehydrated skin → Snail Mucin, hydrating formulas
You want to treat blackheads → BHA
You are looking for a solution for clogged pores → BHA
Your skin is prone to breakouts → BHA, targeted acne treatments
Your skin is dull and lifeless → Vitamin C, Propolis
You want brighter-looking skin → Vitamin C, Propolis
You are looking for a product for the first signs of aging → Peptides, hydrating formulas
You want to care for mature skin → Peptides, PDRN, hydrating products
Your skin is sensitive and has lost its comfort → Soothing and hydrating formulas
You want a simple beginner routine → Gentle cleanser + moisturizer + SPF

Now let’s take a closer look at what each COSRX product is for.

COSRX Snail Mucin – for hydration and more comfortable-feeling skin

If we had to highlight a single COSRX product line that made the brand known worldwide, Snail Mucin would be one of the first that comes to mind.

Snail mucin, or snail secretion filtrate, is primarily popular for its hydrating and skin-caring properties.

The best-known COSRX Snail Mucin products:

COSRX Advanced Snail 96 Mucin Power Essence

The lightweight, gel-like essence is a popular step in a hydrating routine. The product contains 96% snail secretion filtrate.

COSRX Advanced Snail 92 All in One Cream

A richer-textured moisturizer that fits well into a routine for drier, dehydrated skin.

COSRX Advanced Snail Mucin Gel Cleanser

A facial cleanser containing Snail Mucin that focuses on maintaining comfortable-feeling skin alongside cleansing.

Who might it be a good choice for?

Snail Mucin products may be especially interesting if:

your skin is dry or dehydrated,
your skin feels tight after cleansing,
you want a more moisturizing routine,
you want to support your skin’s comfort,
you are looking for a lightweight, layerable moisturizing product.

COSRX BHA – for blackheads and clogged pores

If you primarily struggle with blackheads, clogged pores, or increased sebum production, it is worth exploring COSRX's BHA products.

BHA, or salicylic acid, is a chemical exfoliant and is particularly popular in skincare routines focused on pores.

COSRX BHA Blackhead Power Liquid

One of COSRX's best-known exfoliants.

It can be incorporated into a routine intended to:

reducing the appearance of blackheads,
supporting the maintenance of clean, unclogged pores,
caring for oilier skin,
creating a smoother skin surface.

Who might it be suitable for?

Primarily those who:

have oily or combination skin,
frequently experience blackheads,
struggle with clogged pores,
want to introduce a chemical exfoliant into their routine.

Important!

BHA is an active ingredient, so if you are a beginner, do not use it too often.

Start gradually and observe how your skin reacts.

If you also use retinol, AHA, or other strong active ingredients, it is especially important to structure your routine properly.

COSRX for acne – which product should you choose?

One of COSRX's strengths is its range of products designed for problem-prone, acne-prone skin.

However, it is important to distinguish between caring for acne-prone skin and the medical treatment of acne. Cosmetics can help care for the skin properly, but in cases of persistent or severe acne, it is worth consulting a dermatologist.

From the COSRX range, the following may be particularly interesting:

BHA for caring for pores,
gentle facial cleanser,
moisturizing products,
targeted acne patches.

Why is hydration also important for acne-prone skin?

A common mistake is trying to cleanse oily or acne-prone skin too aggressively.

Over-cleansing and over-exfoliating can lead to irritation and an uncomfortable feeling of tightness.

That is why it may also be important in a COSRX routine designed for acne-prone skin:

gentle cleansing → targeted active → hydration → sun protection in the morning

COSRX Vitamin C – for dull skin and radiance

If your main goal is skin with a more radiant, even-looking appearance, it is also worth exploring COSRX's vitamin C products.

COSRX The Vitamin C 23 Serum

Vitamin C is an antioxidant active ingredient often used in routines for dull skin tone and pigmentation concerns.

The COSRX The Vitamin C 23 Serum is one of the brand's popular vitamin C products.

Who might be interested?

in case of dull skin,
in case of uneven skin tone,
when pigment spots appear,
if you want more radiant skin.

When using vitamin C products, proper broad-spectrum sun protection during the day is especially important.

We already have a separate, detailed article about COSRX vitamin C, so if you are specifically looking for this active ingredient, it is worth reading that as well.

COSRX Propolis – for hydrated and more radiant skin

Propolis is one of COSRX's popular ingredients.

The Full Fit Propolis range may be particularly interesting for moisturizing, nourishing, and radiance-boosting routines.

COSRX Full Fit Propolis Light Ampoule

A lightweight ampoule that you can use in a moisturizing, radiance-boosting routine.

Who might it be suitable for?

If:

your skin looks dull,
you want a more moisturizing routine,
you want to enhance your skin’s comfort,
you are looking for a lightweight ampoule.

COSRX peptides – one option for an anti-aging routine

Peptides have become increasingly popular ingredients in anti-aging skincare in recent years.

The COSRX range also includes peptide-based products.

COSRX The 6 Peptide Skin Booster Serum

The product is formulated with six different peptides, and its lightweight texture makes it suitable for a variety of routines.

When might it be of interest?

If your goal is:

supporting the skin’s elasticity,
more hydrated skin,
a smoother skin surface,
creating an anti-aging routine.

The advantage of peptides is that, combined with adequate hydration and sun protection, they can be part of a simple, sustainable long-term routine.

COSRX PDRN – the brand’s newer-generation products

The COSRX range now also includes 5 PDRN products.

The K-Beauty For You selection currently includes, for example:

5 PDRN B5 Vital Soothing Toner
5 PDRN Collagen Intense Vitalizing Serum
5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask

is also available.

The PDRN range is primarily suited to moisturizing, revitalizing, and anti-aging routines.

COSRX facial cleanser – which one should you choose?

One of the most important steps in a skincare routine is proper cleansing.

COSRX offers several types of facial cleansers, so here too, it is worth starting with your skin’s needs.

COSRX Advanced Snail Mucin Gel Cleanser

If you are looking for a more moisturizing, comfortable cleanse, this could be an interesting choice.

COSRX Low pH Good Morning Gel Cleanser

One of COSRX’s best-known gel facial cleansers.

The lightweight gel cleanser may be particularly appealing to those looking for a simple, everyday cleanser.

If you are specifically looking for a COSRX facial cleanser, read our separate guide, in which we compare the brand’s different cleansers and help you choose the right one for your skin type.

COSRX moisturizer – which cream should you choose?

If you are looking for a moisturizer, it is also worth considering the condition of your skin.

COSRX Advanced Snail 92 All in One Cream

One of the best-known moisturizers in the Snail Mucin product range.

It may be a good choice if:

your skin is drier,
you experience dehydration,
you want a more moisturizing evening routine,
you prefer more comfortable, nourishing creams.

The COSRX range also includes moisturizers with different textures and compositions, so if you have oily or combination skin, it is worth looking for a lighter formula.

COSRX eye care – if anti-aging is also a goal

The skin around the eyes can be thinner and more sensitive, so it may require special care.

COSRX Advanced Snail Peptide Eye Cream

The product is formulated with a combination of snail mucin and peptides.

Suitable for a routine that also focuses on hydrating the eye area and anti-aging care.

Routine by skin type

Not sure how to put together your COSRX routine?

Here are some simple starting points.

For dry skin

In the morning:

gentle facial cleanser
hydrating toner or essence
Snail Mucin
moisturizer
SPF

In the evening:

facial cleanser
hydrating toner
Snail Mucin
moisturizer

For dry skin, it is not necessarily necessary to use an active exfoliant every evening.

For oily skin

In the morning:

gentle cleanser
lightweight moisturizer
serum if needed
SPF

In the evening:

cleanser
targeted active – for example, BHA, at an appropriate frequency
lightweight moisturizer

Oily skin also needs hydration. The goal is not to “dry out” the skin, but to maintain a balanced routine.

For acne-prone skin

In the morning:

gentle cleanser
moisturizer
SPF

In the evening:

cleanser
targeted active
moisturizer

If you use BHA, introduce it gradually and do not automatically combine it with every other active ingredient.

COSRX routine for mature skin

In the morning:

gentle cleansing
antioxidant or hydrating serum
moisturizer
SPF

In the evening:

cleansing
peptides or another targeted serum
moisturizer
eye cream, if you would like to use a separate product

One of the most important elements of an anti-aging routine remains consistent daily sun protection.

How to choose a COSRX product

If you are unsure which COSRX product to choose, do not automatically start with the most popular product.

Ask yourself these three questions:

1. What is my skin type?

dry
oily
combination
sensitive
normal

2. What is my most important concern?

blackheads
acne
dehydration
dark spots
dullness
enlarged pores
first signs of wrinkles

3. What am I already using?

This is especially important when you use active ingredients.

If you already use, for example, retinol, AHA, or BHA, you may not need to add more exfoliants or active serums.

A good routine is not good because it consists of many products. It is good because you consistently use the right products for your skin.
