Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a herbal oil-control essence and a preparation method thereof. Background Art

[0002] The proportion of people with oily skin continues to grow, and oily skin care has received more and more attention: In the past five years, the proportion of consumers with oily skin has shown a slow growth, and the number of consumers with oily skin has increased; this is closely related to the fast pace of life and high pressure of contemporary people. At the same time, with the upgrading of consumer mentality, oily skin care has received attention.

[0003] Current oil control market situation: Over-cleansing can instantly clean skin oil but at the same time, it will stimulate the skin to produce more oil; alcohol addition will dissolve some of the oil on the skin surface, accelerate the loss of moisture on the skin surface, and make the skin dry; physical methods (such as oil-absorbing paper, mud mask, loose powder) when using oil-absorbing paper, absorb oil by pulling and rubbing, which can easily damage the skin and cause skin pores to become larger; at the same time, absorbing the oil on the skin surface too cleanly will make it easier for external dust and bacteria to invade the skin.

[0004] With the improvement of living standards, people pay more and more attention to skin care. People with oily skin face a series of skin problems caused by excessive oil secretion, such as enlarged pores and acne. Existing oil control products have defects such as short-lasting oil control effect, high irritation of ingredients, and low utilization rate of natural herbal effective ingredients. Therefore, there is an urgent need for a herbal oil control essence and a preparation method thereof to solve the above problems. Summary of the invention
