Melting threads,
a lifting film
At the heart of DA99 is a supportive lifting film that our 99.9% naturally derived chitosan melting-thread ingredient forms on the skin. An immediate, physical tightening — and firmness that deepens over time. Melting-thread lifting you can feel, no procedures.
The net-like lifting film
As the 99.9% naturally derived chitosan melting threads dissolve into the essence, the active-rich formula forms a net-like film on the skin. The film tightens instantly, lifting and firming skin that has begun to loosen, while the actives held inside are absorbed gradually to help restore elasticity.
Mildly acidic · protecting the skin barrier
Alkaline products weaken the skin barrier — the skin’s own defense — trapping it in a cycle of constant moisturizing and oil control. DA99 is formulated mildly acidic to protect that barrier; the Vita C and Original ampoules in particular sit at a low pH. As the 99.9% naturally derived chitosan forms its film and lifts, it also creates a healthy home for the skin’s microbiome and helps shield skin from airborne heavy metals and pollutants. That is why we recommend rinsing the next morning with lukewarm water, no cleanser.
