Abstract

The invention discloses a skin care method and a double-liquid skin care suit, and relates to the technical field of cosmetics. The method comprises the steps of providing a first liquid skin care composition which is a high-fluidity liquid system and contains skin conditioning components, providing a second liquid skin care composition which is a semi-fluidity gel system and contains pH adjusting components, mixing the two liquid compositions in a contact manner in the skin using process, and immediately converting the system from a liquid state or a semi-fluidity state into a gel structure or a film forming state with viscoelasticity through physical structure recombination after mixing. The invention can flexibly adjust the product texture according to personal requirements, not only can use liquid essence alone, but also can be mixed to form gel texture, thereby meeting the requirements of different skin types and use situations. By separating the functional components from the thickening system, the stability problem of the active components is avoided, and the personalized skin care experience is realized.

The skin care method of claim 1, wherein the contact mixing comprises: The first liquid skin care composition is mixed with the second liquid skin care composition at the palm of the hand and then applied to the skin surface, or The first liquid skin care composition and the second liquid skin care composition are respectively smeared on the skin surface and then mixed on the skin surface.
  8. 8. The skin care method of claim 1 wherein the physical restructuring comprises interacting the aqueous phase and the polyol system of the first liquid skin care composition with the polymer gel network of the second liquid skin care composition to induce physical rearrangement of the polymer gel structure, wherein the first liquid skin care composition and the second liquid skin care composition are in contact with each other at the skin surface to restructure the physical structure and form a gel-like structure having viscoelasticity within 60 seconds, and are further rendered into a film-forming state within minutes to hours after spreading and resting on the skin surface.
  9. 9. The skin care method of claim 1, further comprising: The first liquid skin care composition alone, the first liquid skin care composition remaining liquid on the skin surface, or The second liquid skin care composition is used alone and remains in a liquid or semi-fluid state on the skin surface.
  10. 10. A dual liquid skin care kit comprising: a first container containing a first liquid skin care composition, the first liquid skin care composition being a high flow liquid system comprising a skin conditioning ingredient; A second container containing a second liquid skin care composition which is a semi-mobile gel system comprising a polymeric thickener and a pH adjusting ingredient; after the first liquid skin care composition and the second liquid skin care composition are contacted and mixed in the skin using process, the system is instantly changed into a gel-like structure or a film-forming state with viscoelasticity from a liquid state or a semi-flowing state through physical structure recombination.

Description

Skin care method and double-liquid skin care suit Technical Field The invention relates to the technical field of cosmetics, in particular to a skin care method and a biliquid skin care suit. Background With the continuous improvement of the skin care demands of people, various products including emulsion, cream, essence, gel and the like appear in the skin care product market. Among them, liquid essence products are widely welcome by consumers due to their light and thin texture and rapid absorption. In the prior art, liquid essence products are usually prepared into specific textures, such as water, emulsion or gel, in advance in the production process by adopting a single formula system and adding components such as a thickening agent, a film forming agent and the like. In the prior art, the prefabricated gel or gel product has a polymer network formed before delivery, active ingredients are in a limited distribution state for a long time, and the diffusion and release are limited by a network structure, so that the efficacy exertion is influenced. Meanwhile, the texture of the prefabricated product is fixed, and a user cannot adjust according to personal skin or seasonal changes. Although some double-tube or double-bin packaged products exist on the market, the products are generally simply stacked layer by layer, no structural level interaction occurs between the two phases, and the real texture transformation and the personalized customization of the use experience cannot be realized. Thus, there is a need for a skin care regimen that can adjust texture during use as desired while ensuring active ingredient stability and efficacy. Disclosure of Invention The invention aims to provide a skin care method and a double-liquid skin care suit, and aims to solve the technical problems that the skin care quality is fixed, the skin care quality cannot be adjusted according to requirements, and the stability is reduced due to incompatibility of active ingredients and a thickening system in the prior art. In order to achieve the above purpose, the present invention provides the following technical solutions: a method of skin care comprising the steps of: Providing a first liquid skin care composition which is a high flow liquid system comprising a skin conditioning ingredient; Providing a second liquid skin care composition which is a semi-fluid gel system comprising a polymeric thickener and a pH adjusting ingredient; Contacting and mixing said first liquid skin care composition and said second liquid skin care composition during skin application; After the first liquid skin care composition is contacted with the second liquid skin care composition on the skin surface, the system is instantly converted from a liquid state or a semi-flowing state into a gel-like structure or a film-forming state with viscoelasticity through physical structure recombination.
