How to choose cosmetics

In recent years, some girls have been suffering from dermatitis, hyperpigmentation, and even "flower face" as a result of improper use of cosmetics. How to scientifically choose cosmetic products has become a must for all girls.

Understanding cosmetics

In the choice of cosmetics, the first thing to understand the chemical composition of cosmetics, strictly prohibited the use of cosmetics containing lead, arsenic, mercury and other harmful to human health. First of all, the most important thing to look at when choosing cosmetics is whether the quality is guaranteed or not. Famous factories and brand names are a reference factor, but the key is to see if the ingredients of his products contain flavors, preservatives, pigments, animal ingredients, and whether they have been tested by dermatology, and to pay attention to whether the products have inspection certificates and production licenses to prevent counterfeiting. Second, learn to identify the quality of cosmetics.

Identify from the appearance

A good cosmetic should be bright, elegant and soft in color. If the color is found to be gray and dirty, with varying shades, it means that there is a problem with the quality. If the appearance is cloudy, oil and water are separated or flocculent, and the cream is dry and cracked, it should not be used.

Identify from the smell

The smell of cosmetics some light, some strong, but all very pure. If it smells pungent and strange, it means that it is a counterfeit or deteriorated product.

Identify from the feeling

Take a small amount of cosmetics and gently apply it to the skin. If it adheres to the skin evenly and tightly and has a smooth and comfortable feeling, it is a cosmetic with a fine texture. If it feels rough, sticky, or even itchy or dry, it is a poor quality cosmetic.

Choice of purchase occasion

At present, domestic consumers generally choose to buy cosmetics from supermarkets or department stores. 32% of consumers in developed countries such as Europe and the United States choose to buy cosmetics from pharmacies, because cosmetics that can be sold in pharmacies have very strict requirements for product safety and efficacy indicators. Therefore, consumers who buy cosmetics in department stores and have been experiencing skin allergy problems can go to drugstores to choose the right cosmetics for themselves.

Try before you buy

Don't underestimate the role of trials (especially if you still have sensitive or allergic skin). "For some women, skin care products are meant to feel and smell good so that they are happy to be accepted and can lead to their daily use."

Choosing based on environmental factors

Personal and environmental factors are taken into account when choosing cosmetics, in addition to the quality of the cosmetics, and the user and environmental factors.

Based on skin type

People with oily skin should use a lotion-type skin care product that is clear; people with dry skin should use a skin care product that is nutritious and moisturizing; and people with normal skin should use a skin care product that is mild.

Depending on age and gender

The skin of children is young and tender, with little sebum secretion, so they need to use special skin care products for children; elderly people have shrunken, dry and thin skin, so they should use skin care products that contain oil, moisturizing factors and vitamin E; men should use skin care products for men.

Choose according to skin color

When choosing cosmetics such as lipstick, eye shadow, foundation and nail polish, they should be coordinated with their skin tone. People with fairer skin tone should use cosmetics with sun protection.

Choose according to the season

The cosmetics used vary depending on the season. In the cold season, it is appropriate to use cosmetics with strong moisturizing and hydrating properties, while in the summer, it is appropriate to use lotions or powder cosmetics.

Store cosmetics properly

Prevent cosmetics from being exposed to sunlight

Cosmetics should not be stored in direct sunlight or light. Because light exposure can cause cosmetics to evaporate, some components can lose their vitality and cause deterioration. The ultraviolet rays of the sun can also cause chemical changes in some substances in cosmetics, which can affect the effectiveness of their use and even cause adverse reactions.

Prevent cosmetics from being frozen

Cosmetics can be kept in the refrigerator's fresh freezer, not in the freezer. During the cold season, it is not advisable to keep cosmetics outdoors or to carry them outdoors for a long time. Because freezing can cause cosmetics to freeze and crack, and after thawing, there will be oil-water separation and coarse texture, which will have an irritating effect on the skin.

Preventing cosmetics from getting damp

Some cosmetics contain proteins, which can easily become moldy when exposed to moisture. Some cosmetics use iron lids, which can easily rust and corrode cosmetics when exposed to moisture, causing them to deteriorate.

Prevent cosmetics from being stored for a long time

Generally, cosmetics have an expiration date of 1-2 years, and the period of storage after opening is shorter. Therefore, it is best to use up cosmetics within the expiration date, rather than stopping and using them until they expire. If a good cosmetic product is carefully stored, it will be worthless if it has passed its shelf life.

Preventing cosmetic contamination

Make sure to tighten the cap of your cosmetics after use so that bacteria do not invade and multiply. It is best to avoid taking it directly by hand when using it, but you can use a clean cotton swab and other tools to take it. If you take too much at one time, you can apply it to other parts of your body and not put it back into the bottle. Before the absolute best, consider whether you will lose cosmetics, especially the so-called big brands by the dark.
