Cosmetic composition for removing black head containing soap paste extract {Cosmetic composition containing Saponaria officinalis extract for removing Black Head}

The present invention relates to a cosmetic composition for removing blackheads containing soap extract as an active ingredient, and more particularly, to a cosmetic composition having an excellent effect of removing blackheads and an excellent effect of removing sebum.

It is a wish of everyone, young and old, to have clear and clean skin, but in reality, people with such skin are not so common, and each person has various skin problems according to the characteristics of the individual skin. Among them, interest in pores has gradually increased, and in particular, in recent years, the desire of consumers to reduce the size of pores as well as to remove the wastes and blackheads in the pores has increased. Spurring

The pores are surgical hair pores of about 0.02 ~ 0.05 mm in diameter with about 20,000 only on the face, and sebum secreted by sebaceous glands flows through the pores to the skin surface.

The pores are one of the biggest enemies of the skin because they hardly get smaller once they are widened. The reason for the widening of pores is that collagen fibers and elastic fibers supporting the pores wall are degenerated as skin aging begins, and as the skin elasticity decreases, skin elasticity is lost and struck and the pores appear to be stretched, or excessive sebum secretion is the main cause.

In puberty, hormones are secreted and sebaceous glands are enlarged, so sebum is secreted. In addition, during pregnancy, stress, and warm weather, sebum secretion is active and pores become larger. By the late 20s, the skin loses its elasticity and becomes dry, causing the skin to stretch and increase pores. Larger pores can easily penetrate waste products such as cosmetics residues and bacteria, which can lead to various skin diseases such as acne.

Normally, sebum is produced in the sebaceous glands and discharged through the pores. This sebum forms a fat film on the skin and hair surface to protect our body from external germs, as well as to protect the skin from UV rays and moisturize the skin. If a disorder occurs in the passage of pores, the pores are enlarged.

In this enlarged pores, the sebum is filled, and the sebum is intertwined with keratin or dust. Entangled sebum is discolored by oxidation when in contact with air. This is commonly called blackhead. That is, the tip is dark, as if black spots are stuck on the skin, and it stands out of the pores. Blackheads occur when the skin is irritated by frequent use of the pack, or when it is frequently exposed to ultraviolet rays and mixed with external dirt. In particular, the area around the nose and cheeks is more exposed to external stimuli such as ultraviolet rays than other parts. .

Conventionally, as a method for suppressing blackheads, crystal peeling, seaweed peeling, laser peeling or the like is used, or a weak peeling agent using glycolic acid or a cums solution or the like is used. As a derivative or topical coating agent, drugs using a mixture of retinoic acid or AHA in alcohol are used. However, the amount of the raw materials is limited due to safety problems when blended into cosmetics, so it is possible to treat pores derived from new natural products, sebum or black. The development of the head restraint raw material is continuously studied.
