Are You Cleansing Your Skin the Right Way?
Why Cleansing Is the Foundation of Skincare
By Soonsu Beauty | July 13 2025
Cleansing is no longer a passive, basic step—it’s now a skincare treatment in its own right. From barrier repair to antioxidant protection, the new generation of cleansers offers much more than a clean face. In this three-part series, we explore how modern Korean cleansers redefine skincare, starting from step zero.
1. From Soap to Science
Traditionally, cleansing was synonymous with stripping—removing dirt and oil with aggressive surfactants. Unfortunately, this often damaged the lipid barrier and caused long-term sensitivity. But now, cleansers are formulated with skin barrier science in mind. They’re low-pH, microbiome-friendly, and even nutrient-rich.
2. Pandemic-Fueled Awareness
During COVID-19, constant mask use led to inflammation and barrier breakdown. People noticed that their expensive serums weren’t working—and began tracing the issue back to their cleansers. The result? A surge in skincare-first cleansing formulas.
3. The Rise of the “0 Step”
Brands like Sulwhasoo, Anua, and APLB now produce cleansers infused with ingredients like ginseng extract, heartleaf, glutathione, and niacinamide. These products treat skin while cleansing—transforming your facial wash into the most important part of your skincare ritual.
4. Ingredient Spotlight: Powerhouse Actives in Korean Cleansers
- Niacinamide – A brightening agent that reduces inflammation and boosts ceramide production to strengthen the skin barrier.
- Glutathione – Known as the "master antioxidant," it helps brighten skin tone and neutralize oxidative stress.
- PDRN (Polydeoxyribonucleotide) – A regenerative compound derived from DNA fragments that accelerates cell repair and healing.
- Centella Asiatica – Rich in madecassoside, it calms redness and supports wound healing.
- Ginseng Extract – Offers revitalizing, anti-aging, and circulation-boosting effects.
- Heartleaf (Houttuynia Cordata) – A go-to for calming acne-prone and inflamed skin.
5. Delivery Systems in Cleanser Technology
Advanced cleansers aren’t just about what’s inside—they’re about how ingredients are delivered. Korean skincare brands use emulsification technology, nano-encapsulation, and proprietary skin-coating techniques to ensure that key actives survive brief cleansing contact and still provide benefits post-rinse.
For example, Sulwhasoo’s Ginseng Cleanser uses a layered oil-in-water coating system to preserve hydration. APLB’s balancing foam uses bio-fermented enzymes to help exfoliate gently while prepping the skin for actives like niacinamide and glutathione.
Clinical studies have shown that when properly formulated, cleansers can enhance skin hydration, reduce inflammation markers, and even stimulate collagen production—yes, even in under a minute of contact time.
