1. Cosmetic quality

First of all, the most important thing to choose cosmetics is to see whether the quality is guaranteed. Generally speaking, it is better to choose famous factories and brand-name cosmetics, because famous factories have good equipment, high product standards and guaranteed quality. Brand-name products are generally trustworthy products and are safer to use. Cosmetics without manufacturer and commodity logo are not available. At the same time, you should pay attention to whether the product has inspection certificate and production license to prevent counterfeiting. Also pay attention to the production date of cosmetics. General ointment and honey products should be purchased within one year after leaving the factory.

Secondly, learn to identify the quality of cosmetics.

① Identification from appearance: Good cosmetics should be bright in color, elegant and soft. If the color is found to be dark, dirty and different shades, it means there is something wrong with the quality. If the appearance is turbid, oil and water are separated or flocs appear, and the paste shrinks and cracks, it cannot be used.

2 Identification from the smell: The smell of cosmetics is elegant and strong, but they are all pure. If it smells pungent, it means it is a fake or a deteriorated product.

③ Perception and recognition: Take a little cosmetic and gently apply it to the skin. If it can be evenly and tightly attached to the skin and has a smooth and comfortable feeling, it is a delicate cosmetic. If it is rough, sticky or even itchy and dry after application, it is inferior cosmetics.

2. Personal and environmental factors When choosing cosmetics, besides the quality of cosmetics, users and environmental factors should also be considered.

① According to skin type: people with oily skin should use refreshing emulsion skin care products; People with dry skin should use nutritious and moisturizing skin care products; People with neutral skin should use mild skin care products.

② According to age and sex: children have delicate skin and low sebum secretion, so special skin care products for children should be used; Old people's skin is atrophic, dry and thin, so they should choose skin care products containing oil, moisturizing factor and vitamin E. Men should choose men's skin care products.

3 according to skin color: when choosing cosmetics such as lipstick, eye shadow, foundation and nail polish. Be sure to coordinate with your skin color. People with fair skin should choose cosmetics with sunscreen function.

④ According to the season: the cosmetics used in different seasons are different. In the cold season, cosmetics with strong moisturizing performance should be selected, while in summer, emulsion or powder cosmetics should be selected.
