The skin condition after dermatological surgery can be changed. As the laser light penetrates into the skin during the procedure it will activate biomolecules which are the cause of the related redness. In addition, it can parch sensitive skin and worsen itching and flaking. The original intention of 'BB cream' is for soothing sensory skin, but not for make-up. The commonly used 'BB cream' is suitable for all skin types and are targeted specially to those who have sensitive and acne-prone skin. It has the advantages of both skin-care and make-up as it improves the skin condition and evens out the skin tone while providing coverage for redness spots and other blemishes. Our study focuses to give the make-up function that naturally correct the brightness and contrast of redness skin, to realize the skin-care function that is effective against sensitive skin.

This paper was described about the preparation of the multi-functional mask pack and its evaluation. Here, the multi-functional effects means the far-infrared emissivity effect due to polyphosphoric acid, the freckles treatment effect and peeling effects due to inclusion complexes, and the skin temperature decreasing effect due to Lavender-extraction compounds. The the hazardous chemicals, viscosity, and pH were determined blow 0.01%, 280 cP, and pH=6.92 in the prepared multi-functional mask pack solution, respectively. The multi-functional mask pack prepared with dipping method in the solution were showed the value of $0.882{\mu}m$ (Far-infrared emissivity) and $3.40{\times}10^2W/m$ at $37^{\circ}C$ (Far-infrared radiation energy), respectively. After taking multi-functional mask pack, the skin moisturizing rate was indicated 35.5%, and the skin temperature was showed in the range of $24{\sim}26^{\circ}C$. The skin stimulation test for the 30 volunteer was showed very strong stability.
