Common questions about K-Beauty – everything you need to know

Get answers to the most common questions about Korean skincare, products, and routines.

What is Korean skincare (K-beauty)?

K-beauty is a skincare philosophy from South Korea that focuses on achieving healthy, hydrated, and radiant skin through several carefully selected steps and innovative ingredients.

What is the difference between Korean and Western skincare?

Korean skincare emphasizes preventive measures, hydration, and the use of mild, natural ingredients, while Western skincare often focuses on treating specific issues as they arise.

What does a 10-step Korean skincare routine entail?

A classic routine includes: oil cleansing, water cleansing, exfoliation, toner, essence, serum, sheet mask, eye cream, moisturizer, and sunscreen.

Do I have to follow the entire 10-step routine?

Absolutely not! You can customize the routine according to your skin type, your needs, and how much time you have. Many start with 3–5 steps.

What is essence and how does it differ from serum?

Essence is lighter in consistency and prepares the skin for subsequent steps. Serum is more concentrated and targets specific skin issues.

Why is double cleansing important?

It removes both oil-based and water-based impurities, making the skin cleaner and more receptive to hydration.

What ingredients are common in Korean skincare?

Snail secretion, Centella Asiatica (Cica), rice extract, ginseng, and propolis are just a few examples of powerful yet gentle ingredients.

Do I need to use sunscreen every day?

Yes! UV rays penetrate even on cloudy days. Sunscreen is essential for maintaining skin health and preventing aging.

How do I choose products that suit my skin type?

Start by identifying if you have dry, oily, sensitive, or combination skin. Then you can filter products based on that on our website.

Can men also use Korean skincare?

Of course! Korean skincare is for everyone – regardless of gender, age, or skin type.
