Hada Labo TokyoTM cosmetics thoroughly hydrate the skin and for many hours maintain high levels of skin moisture. This is what we call the LOCK-in-MOIST effect. Research has shown that Hada Labo TokyoTM WHITE – Intense Hydrating Skin-Plumping Gel anchors moisture inside the skin for much longer than competitive products. The drop in moisture levels in the skin, measured eight hours from application, in the case of the Hada Labo cosmetic was very moderate – not more than 10%. When using competitive products, these levels decreased by almost a half, up to 70% in some cases.
