The quality of the composition table of face cream can be judged from the following aspects:
1. Key ingredients and efficacy: Moisturizing ingredients such as hyaluronic acid, glycerin, etc. can effectively lock in moisture and enhance the skin's moisturizing ability. Hyaluronic acid has a good moisturizing effect at a dosage of 0.02% -0.05%, while glycerol can play a dual role in moisturizing and lubricating. Functional ingredients: such as vitamin C, collagen, A alcohol, etc. Vitamin C has antioxidant and whitening effects, and can promote the synthesis of collagen; Collagen can enhance skin elasticity and firmness; Alcohol is a powerful anti-aging ingredient, but its irritant properties should be noted, with a general addition amount between 0.08% and 0.3%. Plant extracts, such as green tea extract and aloe vera extract, often have soothing, anti-inflammatory, or antioxidant effects.
2. Harmful ingredients and safety: Preservatives: Although preservatives are crucial for preventing product spoilage, excessive or improper use may cause skin problems. Common preservatives such as nipagin esters may cause allergic reactions, and their use must comply with the national safety concentration range. Stimulating ingredients: such as alcohol, spices, pigments, etc., which may cause skin sensitivity or irritation, especially for sensitive skin, should be avoided as much as possible. Heavy metals: Although modern cosmetics production has strict control over heavy metals, it is still necessary to pay attention to whether the product detects heavy metals such as lead, mercury, arsenic, etc., which are harmful to the human body.
3. Ingredient sorting and content: Ingredient sorting: According to national regulations, the ingredient list of skincare products should be sorted in descending order of ingredient content. The first few digits of the ingredient list are usually the main components with higher content, such as water and glycerol. Content determination: Although the specific content will not be directly labeled, it can be roughly determined through ingredient sorting and the commonly used concentration range of common ingredients. For example, if a certain functional ingredient is ranked after preservatives, its content may be less than 1%.
To judge the quality of the ingredient list of face cream, it is necessary to comprehensively consider the key ingredients and efficacy, harmful ingredients and safety, as well as the ranking and content of ingredients. When choosing face cream, it is recommended to choose products with appropriate key ingredients, avoiding harmful ingredients and reasonable ingredients ranking according to your skin texture and needs.
