What is double cleansing?
Double cleansing is a two-step Korean method: first an oil-based cleanser dissolves makeup, sunscreen and sebum, then a water-based cleanser removes sweat and water-soluble debris. The pairing aims to clean thoroughly without the tightness or stripping that one harsh wash can cause.
Do you really need all 10 steps of Korean skincare?
No. The 10-step routine is a menu, not a requirement. Many Koreans use a simple core of cleanser, hydrating toner, moisturizer and sunscreen, adding serums, essences or masks only as their skin needs. The point is consistency and customization, not maximum steps.
Do I really need to double cleanse?
At night, if you wear sunscreen or makeup — yes. Water-based cleansers cannot break down water-resistant sunscreen, so a single cleanse leaves a film behind. In the morning, one gentle cleanse or just water is plenty.
What is a first essence and do I need one?
A first essence is a watery, high-percentage ferment applied straight after cleansing, before anything else. It is a hydration and conditioning step. Pleasant and popular, but genuinely optional.
