Background

The facial mask is a category of skin care products, is a carrier of the skin care products, can isolate facial skin from the external environment in a short time, promotes the skin pores to expand, and carries essence to permeate into the skin cuticle so as to achieve the effects of moisturizing, whitening, resisting aging, balancing grease, relieving fatigue and the like.

Aquilaria agallocha is a resin-containing wood produced by plants of the genus Aquilaria of the family Thymelaeaceae after being injured, and is named because it is fragrant and sinks in water. Since ancient times, eaglewood is both a precious herb and an advanced spice. Lignum Aquilariae Resinatum has effects of lowering qi, warming spleen and stomach, warming kidney, and relieving fatigue. In ancient times, agilawood is used in many countries as a famous and precious spice special for hospitalizing visitors, and is often used as an aromatherapy. In modern times, along with the development and popularization of incense channel culture, the agilawood function is developed more comprehensively, agilawood is more applied to the aspects of daily chemical skin care, aromatic health preservation and the like, and a plurality of agilawood products are successively appeared and pursued by the public.

Some agilawood masks are already available on the market and have a certain moisturizing effect. However, the existing agilawood facial mask still has some problems, for example, because the agilawood vegetable oil is a rare spice with a medicinal function generated by stress reaction of reodoraceae plants after being injured, natural resources of the agilawood vegetable oil are in short supply, the existing agilawood vegetable oil is mostly obtained after artificial planting and artificial injury, the agilawood vegetable oil is produced by means of knife cutting, fire drilling, bacterial colony infection and the like, the quality of the finally obtained agilawood vegetable oil is possibly not pure enough, and further, the phenomenon of allergy is caused after some consumers use the agilawood facial mask.
