The invention discloses an oil-control pore-shrinking composition containing lactobionic acid. The oil-control pore-shrinking composition comprises the following components in percentage by weight: 0.0001-20% of lactobionic acid, 0.0001-30% of a flos spiranthis sativae extract, 0.0001-20% of nicotinamide and 0.0001-20% of carnitine. The oil-control pore-shrinking composition disclosed by the invention can intelligently identify aged keratinocytes, remove aged dead cells and promote the regeneration of the keratinocytes. The oil-control pore-shrinking composition can remove dirt in pores, helpthe proliferation of hyaluronic acid and collagen in a dermis layer, increase the water content of skin, visually shrink the pores and enable the whole skin to become compact and elastic. The flos spiranthis sativae extract can effectively shrink coarse pores, inhibit abnormal oil production of hair follicles and inhibit bacterial reproduction and prevent acnes. Moreover, the oil-control pore-shrinking composition is mild and non-irritant, can serve as an oil-control pore-shrinking active component and is applied to various cosmetics.

A skin-substitute is constructed by homogenizing an acellular dermal tissue matrix into a slurry, pouring the slurry into a mold, and lyophilizing the slurry.

The invention provides an acellular matrix particle product for soft tissue filling and repairing, and a preparation method of the acellular matrix particle product. The acellular matrix particle product comprises the following components in percentage by mass: 2.0-10% of acellular matrix particles, 0.1-5.0% of suspending aids and the balance of water for injection, wherein the acellular matrix particles are formed by mixing one or more of non-crosslinked acellular matrix particles, low-crosslinked acellular matrix particles and high-crosslinked acellular matrix particles. The decellularized matrix particle product provided by the invention is good in elasticity, soft in texture and high in resilience force, can form decellularized matrix particle products with different degradation gradients, different degradation time and different space structures according to the preparation technologies of the decellularized matrix particle product, is suitable for filling and repairing soft tissues, including dermal superficial tissues, dermal deep tissues, subcutaneous tissues and the like, and has a good application prospect.
