How does skin care white know the ingredients of skin care products?

Novices first understand the ingredients of skin care products from three dimensions: dosage form, efficacy and concentration.

Skin care products ingredients

The form of medicine

efficacy

concentrate

A dosage form:

Determine the modules of skin care products, which are closely related to ingredients.

B concentration:

Without concentration, it is equal to empty talk, just like a bird without wings, it is equal to empty talk about flying.

efficacy

Determination of active ingredients, active ingredients are the key point to discuss the efficacy of skin care products.

Skin care ingredients-dosage form

Usually when we discuss a product, we usually discuss the dosage form of the product, and the dosage form determines the module of skin care products. Taking cleansing products as an example, cleansing products are divided into facial cleanser, makeup remover and cleansing oil. From the dosage form, facial cleanser is usually divided into soap-based cleansing, alkyl sulfate cooling salt cleansing, amino acid cleansing and alkyl sugar cleansing. Generally, the surfactant of makeup remover is nonionic surfactant. cleansing oil uses few surfactants, and cleansing oil products generally do not need antiseptic components.

Skin care ingredients-efficacy

The efficacy of skin care products determines the effective components of products. Functional effective components generally include moisturizing components, whitening components, anti-aging components, sunscreen components, Shu Min/anti-inflammatory components, acne removing components, etc. Only by knowing the effective ingredients can we better analyze skin care products.

Skin care ingredients-concentration

In addition to ingredients, skin care products also depend on the concentration of effective ingredients. But the higher the content of active ingredients, the more effective it is, which is related to the effective concentration, safe concentration and cost-effective concentration of active ingredients in skin care products. Taking ascorbic acid as an example, it is found that under the condition of pH=3.2, the permeability of ascorbic acid with a concentration of 20% is the highest, which is the cost-effective concentration mentioned here. Looking at 30% ascorbic acid, it is doomed to be thankless.
