Abstract
Description
[Technical Field]
[0001] The present invention relates to a beauty serum penetration brush that can inject lotion into the skin or spread it on the surface of the skin. [Background technology]
[0002] BACKGROUND ART Conventionally, there has been known an instrument that uses fine needles called microneedles to administer a drug or the like into the epidermis of the skin. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2023-147867 Summary of the Invention [Problem to be solved by the invention]
[0004] The discharge part with tiny protrusions described in Patent Document 1 injects beauty serum using several beauty needles. In order to inject beauty serum into all blemishes, freckles, rough skin, etc., a large amount of beauty serum must be used.
[0005] Cosmetic needles cannot be easily used on the entire face due to skin irritation.
[0006] The present invention has been made in response to such circumstances, and aims to provide a new beauty serum penetration brush that can penetrate liquid into spots and freckles on the skin, as well as rough skin on the entire face. [Means for solving the problem]
[0007] The beauty serum penetration brush of the present invention is a beauty serum penetration brush, the brush section of which is about 15 mm long, and which comprises a cylindrical handle, the brush section attached to the tip of the handle, and an adjustable cover arranged to cover the handle section or at least a portion of the brush section and configured to be movable in the longitudinal direction of the handle, and is characterized in that the length of the brush can be changed by moving the adjustable cover depending on the location where the beauty serum is to be penetrated and the condition of the skin.
[0008] One embodiment of the serum penetration brush of the present invention is a brush in which the brush portion of the serum penetration brush is immersed in the lotion or emulsion contained in a serum transfer container, and the brush portion is allowed to penetrate the serum before use.
[0009] One embodiment of the beauty serum penetration brush of the present invention is one that can be used for hair growth simply by replacing the lotion in the beauty serum transfer container with hair growth lotion for scalp use. [Effects of the Invention]
[0010] Experiments have proven that the quickest way to remove freckles and blemishes is to quickly detect their appearance on the head or scalp. One day, I discovered 15-16 freckles clumped together on the top of my forehead. I immediately tested it with a prototype beauty serum penetration brush, and was able to remove most of them in about 2-3 months. Furthermore, I discovered that applying cosmetics with the brush within 1-2 months of the freckles' appearance caused a black liquid to come out of the freckles. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0012] The beauty serum permeation brush 1 of the present invention will be described with reference to FIGS.
[0013] The serum penetration brush 1 of the present invention comprises a cylindrical handle 7, a brush part 4 provided at the tip of the handle 7, and an adjustable cover 2 arranged to cover at least a portion of the handle 7 or the brush part 4 and configured to be movable in the longitudinal direction of the handle 7.
[0014] In this embodiment, the handle 7 is cylindrical as shown in Figure 1, and the brush part 4 is attached to the end of the cylinder with a nozzle 9. The brush part 4 is made of a material such as animal hair, polybutylene terephthalate, nylon, or PET.
[0015] An adjustment cover 2 that allows the length of the brush part 4 to be adjusted is attached to the outside of the cylinder of the handle 7.
[0016] A fixing screw 3 for adjusting the length of the brush part 4 is provided on the side of the adjustment cover 2 for adjusting the length of the brush part 4. The length of the brush part 4 can be freely changed from about 0 to 15 mm, so that the hardness of the brush part 4 can be adjusted.
[0017] For freckles that appear on the face, body, scalp, etc., the length of the brush part 4 is adjusted to about 0.5 mm, the tip of the brush part 4 is dipped in lotion that is effective against freckles, and the brush is lightly pressed onto the freckles to pat, thereby achieving results faster than applying the lotion by hand.
[0018] The brush part 4 is made up of a bundle of fine, particularly soft bristles with a thickness of about 0.1 mm to 0.03 mm, and can retain a sufficient amount of lotion by being immersed in the lotion.
[0019] Figure 4 shows how to use the beauty serum penetration brush 1. The brush part 4 of the beauty serum penetration brush body 1 is immersed in the lotion or emulsion 8 contained in the beauty serum transfer container 5, and the liquid penetrates the brush part 4, allowing it to penetrate into the skin even over blemishes and freckles.
[0020] The tip of the brush part 4 of the beauty serum penetration brush of the present invention is flat and horizontal. Therefore, even if you tap the skin with the penetration brush, the brush part is flat and will not enter the pores of the skin.
[0021] When using a serum penetration brush to treat rough skin on the face, it has been found that by using a longer brush head to allow the lotion or cream to penetrate the brush, and then gently moving the brush back and forth along the skin's texture, the results are much faster than when applying the product with the palm of your hand.
[0022] The short brush length allows you to save on the amount of serum you use.
[0023] When purchasing a beauty serum, listen carefully to the explanations of the store where you purchase it, or if possible, do your own research and recommend a beauty serum made by a major pharmaceutical manufacturer. [Explanation of symbols]
