Tissue mask dedicated to skin care is a fast-rising category worldwide, due to the pleasant experience to creating pampering a “myself” moment, associated with a very strong instant skin benefit like hydration, radiance, freshness etc. Tissue mask became a beloved cosmetic product, rapidly integrated into the consumer’s skincare routine.

However, over 90% of tissue masks mainly deliver a hydrating effect, that is why consumers also think tissue mask could only be hydration function. However, this hydration efficacy cannot be maintained very long, as a usual ante skin condition is restored within 2-3hours. As a tissue mask is often applied before sleep, the skin condition will return to usual on the following morning.

Due to the large amount of mask juice used in one application, to keep a good skin fresh feeling, traditional tissue mask juice always comprises aqueous formulae with classic carbomer polymer, explaining why a classic tissue mask only provides hydration.

Attempting to develop a brightening mask, a light emulsion structure was created, of a very balanced oil and emulsifier system, which could help: 1) to stabilize phenylethyl resorcinol which is key functional active to ensure a long-term skin brightening, a skin tone evenness effect; 2) to keep good skin moisturization effect and long lasting; 3) to allow the introduction of boron nitride which could bring natural optical effect, and induce a skin desaturation aspect, much helping to obtain a great natural skin brightening effect, maintained overnight; and 4) to comprise a strong anti-oxidation ingredients of Vit C derivative (3-O-ETHYL ASCORBIC ACID) & Vit E to further boost long term skin brightening.

As determined by the Chromasphere technology (N=4 trial which does not have statistical significances), the retained formula led to immediately increase the skin lightness by + 1.57 and maintained an increased skin lightness by +0.99 6 hours post application. In blind use test (N=120), when compared to formulae comprising different dosages of the actives, the retained formula was also ranked first in the skin brightening result obtained the morning, when applied overnight.
