Cosmetic composition, e.g. an anti-ageing composition, comprising retinyl palmitate (pref. 0.25-0.5 wt.%), Silybum marianum seed oil (pref. 1-3 per cent by weight), betaine (pref. 2-4 weight per cent)

The application belongs to the technical field of cosmetics and skin external preparation, and discloses a retinoid, a preparation method and application thereof. The compound is formed by covalently coupling a Schiff base or a kinin releasing enzyme cleavable peptide bond (L) and a free L-amino acid, a di- to hexapeptide or a C6-C22 fatty acid ester (P) of the retinol parent (R), and the structural general formula is R-L-P. The compound has a 12-week stability rate of ≥80% in a 25℃ aqueous preparation, is recognized by a keratin layer carboxylic acid esterase and a kinin releasing enzyme KLK-5 / KLK-7 after being applied to the skin, is subjected to enzymatic cutting in a skin acidic cuticle (pH 4.5-5.5) microenvironment, and releases free retinol at a fixed point. Compared with retinol palmitate, the in-situ release efficiency of the compound of the application is increased by 2.5-4.5 times, while the risk of systemic absorption is significantly reduced, and the incidence of sensitive skin irritation is ≤6.7%.

A whitening nanocomposition, a preparation method therefor, and use thereof. The whitening nanocomposition comprises an active ingredient and a nanocarrier. The active ingredient is coated and / or adsorbed by the nanocarrier. The active ingredient comprises the following components: 1-15 parts by weight of α-arbutin, 1-15 parts by weight of nicotinamide, 1-10 parts by weight of 3-o-ethyl ascorbic acid, 0.1-1 part by weight of a Centalla asiatica extract, and 1-5 parts by weight of retinyl palmitate. The nanocarrier comprises the following components: 5-10 parts by weight of an emulsifier, 5-20 parts by weight of a polyol, 0.1-5 parts by weight of a phospholipid, and 40-60 parts by weight of water. The whitening nanocomposition has good skin permeability and retention performance and enables high-concentration enrichment, prolonged retention, and sustained release or controlled release within a target tissue, so as to be effectively taken in by target cells, thereby improving bioavailability and enhancing the whitening effect.

The application belongs to the technical field of compositions, and provides a moisturizing eye composition, a preparation method and application thereof. The moisturizing eye composition provided by the application is combined by soybean lecithin, retinol palmitate liposome, lutein, oligomeric hyaluronic acid and ethylenediaminetetraacetic acid in a specific ratio, and good synergies can be achieved among the components, the effect of relieving asthenopia, protecting eyesight and maintaining normal vision is improved, and the effect of improving and relieving the symptoms of dry eyes and dry eyes caused by various reasons (such as fatigue, wearing contact lenses, using electronic products, overuse of eyes, etc.) is improved.

The invention discloses a liposome composition with firming and anti-wrinkle effects as well as a preparation method and application thereof, and belongs to the technical field of cosmetics. The liposome composition contains a phalaenopsis aphrodite extract, a radix pseudostellariae extract, hydrogenated lecithin, PEG-40 hydrogenated castor oil, polyglycerol-6 octoate and phytol, and further contains retinol palmitate, tocopherol and other antioxidants, a humectant, a bacteriostatic agent and a solvent. The liposome composition with the particle size of 100-300 nm is obtained through high-pressure microjet treatment, the active ingredient encapsulation efficiency of the liposome composition is high, the liposome composition has the excellent transdermal absorption effect, meanwhile, the composition can efficiently promote synthesis of type I collagen, the firming and anti-wrinkle effects are remarkable, and the liposome composition is suitable for preparing skin care products such as water aqua, emulsion, cream, ointment or facial masks.

The invention discloses a skin repair mask and a preparation method thereof, and relates to the technical field of facial beauty care, the skin repair mask comprises a mask base material and mask liquid attached to the mask base material, the NMN / retinol palmitate / ergothioneine compound nanocrystal moisturizing and repairing lotion is prepared from the following components in parts by weight: 0.5 to 3.0 parts of liposome-coated NMN, 0.3 to 2.0 parts of retinol palmitate / ergothioneine compound nanocrystal, 5.0 to 15.0 parts of moisturizing and repairing component, 0.1 to 2.0 parts of soothing and anti-inflammatory component, 0.1 to 0.8 part of thickening agent, 0.1 to 0.5 part of preservative, 0.01 to 0.1 part of chelating agent, 0.01 to 0.2 part of essence and the balance of deionized water, wherein the total amount of the components is 100 parts.
