Description

Anti-relaxing, anti-firming peptides and cosmetic products containing the same

Technical Field

The present invention relates to non-natural peptides with anti-relaxing, tightening effects and their use in cosmetic and personal care compositions.

Background

Skin aging is a phenomenon of skin aging caused by natural factors or non-natural factors. After birth, the skin tissue of a person is developed increasingly, the function of the person is active gradually, and the person starts to degenerate when the person reaches a certain age, and the degeneration is gradually performed unconsciously. The growth period of skin tissues generally ends at about 25 years old, which is called as 'bending angle of skin' by some people, since then, the growth and the aging are carried out simultaneously, the elastic fibers of the skin gradually become thick, and the aging of the skin is slowly and obviously in the early aging period of 40-50 years, although the aging degree can be different from person to person.

Skin aging is the result of the combined action of the intrinsic physiological mechanism of human aging and the damage caused by external wind, sunshine, environmental pollution and the like. Reasonable nutrition can partially inhibit physiological aging, but is difficult to protect the skin from the external environment. Premature aging of the skin can only be inhibited by timely supplementation of nutrients.

While the balance of body nutrients is important to maintaining healthy skin and may not rejuvenate skin, ignoring this will greatly accelerate skin aging. Certain nutrient deficiencies, such as vitamin C, vitamin B complexes, and essential fatty acids, are known to cause various dermatitis and other skin disorders. If slightly absent (which is common but often overlooked), it may not cause clinical symptoms, but affects the ability of the skin to heal and renew.

Skin aging is usually manifested in skin elasticity, skin wrinkles and roughness, and moisturizing intensity. The simple use of moisturizers in daily life is obviously insufficient for preventing skin aging. Environmental, sunlight, pressure and other factors can cause free radicals to greatly damage skin and promote skin aging to accelerate. At this time, the skin is also prone to spots, fine lines and the like, so that an antioxidant skin care product is required. Aging causes body aging, slow skin metabolism, and degeneration of collagen and elastic fiber of skin.

For a more clear illustration of the invention, reference is now made in detail to the following examples, which are intended to be purely exemplary of the invention and are not to be interpreted as limiting the application.

Examples

The following examples are intended to illustrate the invention in a non-limiting manner.

Example 1: effect on type I collagen Synthesis

Human skin fibroblasts were plated on 48-well plates at 1 × 10⁵cell/ml, cultured for one day so that cell fusion reaches about 60%, and cultured on FBS-free medium for another day. Preparing DMEM medium without FBS, and dividing into A, B, C, D IVGroup A, group A with deionized water, group B with the peptide of SEQ ID NO:1 so that the concentration was 10ppm, group C with the peptide of SEQ ID NO:2 so that the concentration was 10ppm, and group D with the peptides of SEQ ID NO:1 and SEQ ID NO:2, respectively, so that the concentrations were 5ppm, respectively. Collecting cultured human skin fibroblasts, washing with phosphate buffer solution, transferring into above four groups of culture medium, and culturing in CO₂The culture was carried out in an incubator for 48 hours. To evaluate the expression of Procollagen, the culture broth obtained by the above culture method was quantitatively analyzed using a Type I Procollagen C-peptide Kit (Procollagen Type I C-peptide (PIP) EIA Kit, Cat #. MK101, Takara, Japan). In a coated 96-well plate provided in the kit, an anti-collagen antibody as a primary antibody was treated with the supernatant at 37 ℃ for 90 minutes, then washed 3 times with TPBS (0.1% Tween 20in PBS), and after an anti-mouse IgG (mouse IgG) as a secondary antibody was reacted for 90 minutes, washed 3 times with TPBS. After an alkaline phosphatase substrate solution (1mg/mL p-nitrophenyl phosphate-diethanolamine buffer) was reacted at room temperature for 30 minutes, absorbance at a wavelength of 405nm was measured with a microplate reader.

TABLE 1

According to the data, compared with a blank control, the two peptides can obviously increase the synthesis of the type I collagen, and the two peptides obtain an effect which is obviously better than that of a single peptide under the condition that the total protein concentration is the same, so that the two peptides have a synergistic effect on promoting the synthesis of the type I collagen.
