Description

The Cosrx Advanced The Vitamin C23 Serum is a highly concentrated vitamin C serum with ascorbic acid and squalane that brightens your complexion and gives it new vitality. The light, fast-absorbing texture is effortlessly absorbed into the skin and leaves no sticky feeling.

At the heart of the formula is pure ascorbic acid in high concentration, which, together with 3-O-Ethyl Ascorbic Acid, ensures that your complexion appears overall brighter and more even. Squalane and sunflower seed oil moisturize the skin, while hyaluronic acid additionally ensures that the skin noticeably retains moisture. Niacinamide completes the effect and contributes to a more even complexion. Caffeine and adenosine complement the formula and contribute to an overall more vital appearance, while licorice root extract and carrot root extract further support the skin's appearance. Camellia oil and safflower oil finally give the skin more suppleness.

This serum is suitable for all skin types yearning for a brighter, more even complexion – especially for tired-looking or uneven skin, the highly concentrated vitamin C formula shows its strengths. Due to its light, fast-absorbing texture, it is also well suited for combination skin.

How does it solve my skin problems?

The serum shines with a concentrated formula containing 23% pure vitamin C, which helps to restore radiance to dull skin. Niacinamide helps to reduce uneven skin tone, leading to a clearer complexion. Hyaluronic acid provides intense hydration to visibly reduce dryness.

F.A.Q.

How do I find the right skincare for my skin type?

Our product selection is curated so that you can filter specifically by skin type and skin need.

If you are unsure, our customer service will be happy to help you put together a suitable routine – personally and straightforwardly.

Because every skin is individual and deserves products that truly suit it.

Are the ingredients skin-friendly and safe?

All products are sourced from verified, trustworthy K-Beauty brands.

The ingredients are dermatologically tested and comply with European safety standards.

We prefer formulations that avoid irritating additives and instead rely on mild, natural active ingredients.

How do I use the products correctly?

K-Beauty is based on the principle of layering – multiple light skincare steps that complement each other.

Always start with cleansing, follow with watery textures (toner, essence), and finish with nourishing creams or sun protection.

This way, all products can unleash their maximum effect.

Are the products vegan or cruelty-free?

Many of our brands are vegan and all products are cruelty-free.

In each product description, you will find detailed information on ingredients and certifications.

Transparency is important to us – so you can care with a good conscience.

How long are the products good for?

The shelf life is indicated on each package and product page.

After opening, you should adhere to the recommended PAO ("Period After Opening") indication (e.g., 6M or 12M).

Make sure to store products in a cool, dry place, protected from direct sunlight.
