Description

Lifting cosmetic composition containing magnetic particles {A LIFTING COSMETIC COMPOSITION COMPRISING MAGNETIC PARTICLE}

The present invention relates to a lifting cosmetic composition comprising magnetic particles as an active ingredient. In the cosmetic composition of the present invention, one of the first liquid and the second liquid is applied to a part of the face and the other is applied to the remaining area of the face to provide skin pulling properties, or the first liquid is applied to the face and attracted therewith. By wearing a metal article (eg, glasses, precious metals, etc.) having a skin pulling property can be provided.

The stratum corneum (SC) exists in the outermost layer of the skin and plays a role in protecting our body from external harmful microorganisms, UV rays, pollutants, and heat, and controlling skin moisture evaporation and skin moisture retention. carry out

The stratum corneum is known to function as a skin barrier, and is known to have the largest surface area in our body.

The stratum corneum of the skin is composed of dead keratinocytes piled up layer by layer, and intercellular lipid components such as ceramide, cholesterol, and fatty acids attach dead keratinocytes to maintain the shape of the skin barrier.

The intercellular lipid component has a function of preventing skin penetration of external substances and preventing the amount of water evaporated from the surface of the skin, that is, Transepideramal Water Loss (TEWL).

In addition, because the natural moisturizing factor (NMF) exists in high concentration in healthy human keratinocytes, it lowers the tension of the skin surface and receives the repelling force of moisture from keratin, which directly affects moisturizing and inhibits skin from drying out.

Clinically, in dry skin, the surface of the skin is dry, the elasticity is reduced, and keratin detachment (scaling) is likely to occur.

When skin elasticity decreases, wrinkles form and the skin loses vitality, so maintaining the moisturizing power of the skin surface is a good way to maintain skin elasticity.

On the other hand, among the components of the dermal layer of the skin, factors affecting skin elasticity and wrinkles are collagen and elastin.

Collagen is a major component of the extracellular matrix (ECM) and consists of two α1(I) chains and one α2(I) chain. It is known.

Elastin is the protein that supports these collagens. Elastin has very high elasticity and has a property of returning to its original shape even when contracted or relaxed, and skin elasticity can be maintained due to such elastin fibers.

However, matrix metallo-proteinase (MMP) and elastin degrading enzymes are generated from various stimuli that cause external and internal aging, and collagen and elastin are decomposed, resulting in wrinkles and loss of elasticity, resulting in skin aging. can be a major cause of

Recently, the number of people seeking ways to prevent or delay skin aging as much as possible in dermatology or plastic surgery is rapidly increasing, and methods that can delay skin aging or maximize skin aging are being actively studied. .

For example, a method of penetrating an active ingredient for preventing skin aging into the skin non-surgically and a wrinkle lifting procedure may be mentioned.

In the case of wrinkle lifting procedures, it is common to inject active ingredients into the treatment area, which can cause various side effects such as swelling and pain.

Therefore, rather than such a wrinkle lifting procedure, it is possible to effectively improve the phenomenon of skin losing elasticity and sagging due to aging by developing cosmetics that can effectively penetrate active ingredients into the skin or physically smooth out wrinkles on the skin surface. Demand for surgical skin aging prevention technology is increasing.

The present inventors have completed the present invention as a result of studying a method for naturally smoothing skin wrinkles through cosmetics widely used in daily life.
