After casually applying half a tube of essence, the hydration mode kicks in immediately. After use, I can clearly feel that my skin is incredibly moisturized. The cleansing mode is also very effective. I alternate through all six modes regularly (cleansing + whitening + hydration + V-face + eye care + cold compress). It’s as if my entire face has been renovated—my skin is tender, stable, bright, and firm! What’s the difference between this and bringing the beauty salon home? Definitely deserves a good review.
