Description

Cosmetic composition for removing blackheads {Cosmetic composition for removing blackhead}

The present invention relates to a cosmetic composition for removing blackheads, and more particularly, extracts of witch hazel, sage, peppermint, lemon balm leaf, burdock, mistletoe, red pepper sprouts, soapy leaf and soybean berry as active ingredients. It relates to a cosmetic composition for removing blackheads while minimizing sebum and blackhead removal ability.

Our skin causes various skin troubles due to various social and environmental pollutions. If we leave the epidermal layer contaminated with the environment, capillaries are contracted and blood circulation is not good and clogged pores. The lump formed by the accumulation of waste and secreted sebum is called whitehead, which is oxidized when it comes into contact with oxygen in the air and becomes blackhead. In other words, the skin is dark as if it is stuck with black spots, and it refers to the condition of sebum coming out of the pores.

In addition, the pores are small holes in which the oil secreted from the sebaceous glands flows to the skin surface, and refers to the entrances where hairs grow. There are about 20,000 pores on the face of the human face because there are 100 to 120 pores per cm 2. The reason for the widening of pores is that collagen fibers and elastic fibers that support the pores wall degenerate as skin aging begins, and as the skin elasticity disappears and falls, the pores appear to be stretched, or excessive sebum secretion is the main cause.

These blackheads are not easy to remove, and even though they are removed, they are usually physically removed through a cotton swab or sebum remover, which causes a great deal of stress on the skin, and the pores from which the blackheads are removed remain unrestricted. In most cases, additional procedures to shrink pores are needed.

Recently, as consumers' desire to remove the blackheads and whiteheads in the pores as well as reduce the size of the pores increases, products related to the same have been developed in the cosmetic industry.

However, most of the products for removing blackheads are mostly packs or scrubs, and chemicals are mainly used, which causes chemical and physical irritation to the skin, causing reddening and widening pores as the frequency of use increases. There was a problem that the skin condition worsened.

The present invention is to solve the above problems, including the natural plant extracts of witch hazel, sage, peppermint, lemon balm, burdock, mistletoe, red pepper herb, bark leaf and biscuits as an active ingredient, while minimizing skin irritation And to provide a cosmetic composition with improved blackhead removal ability.

Still another object of the present invention is a sebum removal agent comprising an extract of witch hazel, sage, peppermint, lemon balm leaf, burdock, mistletoe, horseradish greens, soap leaf and soybean fruit as an active ingredient; It provides a blackhead removal cosmetic composition comprising; and a second agent for pore contraction and soothing skin containing enantiaclonanta bark extract, witch hazel extract and zinc PCA (Zinc PCA).

Still another object of the present invention is to provide a black mask removing sheet mask kit including the first agent, the second agent, and a cotton swab.

Test Example  1. Blackhead removal degree evaluation

The sheet mask containing the compositions of Examples 1 to 4 and Comparative Examples 1 to 3 prepared in Preparation Example 2 was attached to the skin (nose and its surroundings) where blackheads were heavily distributed and left for 10 minutes, followed by swelling. The degree of sebum and blackhead discharged to the skin surface was visually examined.

As a result, when the sheet masks of Examples 1 to 4 were used, the blackheads were effectively discharged, and in particular, the sheet masks of Example 1 were found to discharge the largest amount of blackheads. In contrast, when the sheet masks of Comparative Examples 1 to 3 were used, almost no blackheads were discharged.

Test Example  2. Confirm the effect of shrinking pores and calming skin

After removing the black head discharged in Test Example 1 with a black cotton swab, the sheet mask containing the composition of Examples 5 to 7 and Comparative Examples 4 to 6 prepared in Preparation Example 3 was removed skin (nose And then attached to), after leaving for 10 minutes, the pores shrinkage and skin soothing effects were examined.

As a result, when the sheet masks of Examples 5 to 7 were used, sufficient pore shrinkage and skin soothing effects were exhibited, and particularly, the effect was best when the sheet mask of Example 4 was used. On the other hand, when the sheet mask of Comparative Examples 4-6 was used, compared with Examples 5-7, there existed little pore contraction and skin soothing effect.

Skin conditions and test procedures when tested using the blackhead removing sheet mask of Example 1 and the pore contraction and skin calming sheet mask of Example 5 are shown in FIGS. 4 to 6.

Test Example  3. Skin irritation test

For 25 subjects, the blackheads were removed using the sheet masks of Examples 1 and 5 by the methods of Test Examples 1 and 2, and commercially available products [Christian Balmi, Hansol Sales, Product Name: Glow [SPA] was used to compare the skin irritation when the blackhead was removed.

The skin stimulation experiment was to compare the irritation felt by the subject after using in each composition to check the skin irritation by checking each item of no stimulation, tickling, stinging and burning, the results are shown in Table 3 below.

Stimulation degree Example 1 and Example 5 (persons) Other company's product No irritation 18 4 Tickle 3 7 Stinging 2 10 Burning 0 2

Looking at the results of Table 3, while there are many subjects who feel stinging and tickling in the case of commercially available products, when using the sheet mask according to the present invention (Examples 1 and 5), weak stimulation in tickling and stinging But there were many partial irritation.

Test Example  4. Blackhead  Removal Satisfaction Rating

Thirty subjects were evaluated for their satisfaction with blackhead removal using commercially available blackhead removal products and the sheet masks of Examples 1 and 5.

The results are shown in Table 4 below.
