Description

Technical Field

[0001] This invention relates to the field of skin care technology, specifically to a whitening and freckle-removing composition and a whitening and freckle-removing facial mask. Background Technology

[0002] Skin problems are becoming increasingly common due to a variety of factors, including ultraviolet radiation, life stress, endocrine disorders, and unhealthy lifestyle habits. Among them, dull skin tone, melasma, and pigmentation left after acne healing (i.e., acne scars) are the three major skin problems that plague consumers and seriously affect their appearance.

[0003] The market is currently flooded with whitening and freckle-removing products, but their active ingredients and mechanisms of action have certain limitations. For example, while chemically synthesized products have a clear whitening effect, long-term use of certain ingredients may pose potential safety risks and easily lead to drug resistance. Some whitening masks on the market currently only have a matrix that can play a simple role in adsorption and sealing, and their ability to carry and release active ingredients is not good. Their adhesion to the skin and breathability also need to be improved, making it difficult for the effective ingredients to be fully absorbed by the skin, thus affecting the final whitening and freckle-removing effect.

[0004] Based on this, this application proposes a traditional Chinese medicine composition that improves dull skin tone and lightens age spots, with mild effects and high safety. Summary of the Invention

[0121] One hundred volunteers (aged 25-45) with facial pigmentation problems such as melasma and freckles were selected. They were randomly divided into two groups: Group A (50 people) used the whitening and spot-removing mask prepared in Example Fourteen, and Group B (50 people) used a blank matrix mask without the composition of this invention. The masks were used three times a week for eight consecutive weeks.
