The shelf life of eyebrow dye. Can the eyebrow dye be used after it expires?

Eyebrow tint is a cosmetic product that we are all familiar with. Many people use it. Generally, cosmetics have a shelf life. So we need to understand the shelf life of eyebrow tint? Can eyebrow tint still be used after it expires?

The shelf life of eyebrow tint is generally three years, and it can be used up within three years after opening. Mascara or eyebrow tint is a paste, which needs to be stored in a dry environment, and attention should be paid to the sealing of the paste. However, if the eyebrow tint has deteriorated due to improper storage, it should not be used again, because the chemical components in it will cause certain allergic reactions to the skin and eyebrows. If it is not carefully stored, this paste can generally only be used for 6-9 months. Usually we say that the shelf life of skin care products is generally 3 years, and that of cosmetics is generally 5 years, but it only refers to the shelf life before opening. After opening, products, whether skin care products or cosmetics, will not have such a long shelf life. The closer the product is to the eyes, the shorter the shelf life will be, and the eyes are more sensitive, so this kind of cosmetics is best used up within 3-6 months.

It cannot be used. The shelf life is composed of two elements, one is the storage conditions, and the other is the period. The two are closely related and inseparable. The storage conditions must be marked on the product label, usually including: room temperature, storage away from light, cool and dry place, refrigerated environment can be stored longer, etc. If the product storage conditions do not meet the regulations, the shelf life of cosmetics is likely to be shortened. Usually we say that the shelf life of skin care products is generally 3 years, and that of cosmetics is generally 5 years, but this is just the shelf life before opening. After opening, products, whether skin care products or cosmetics, will not have such a long shelf life. There is usually an icon on the product that looks like a small can that has been opened, and the icon is marked with words such as "6M" and "12M", which means that the best use period is 6 months or 12 months after opening. Even different brands of the same product have different expiration dates, and cosmetics have a longer expiration date. Makeup artists are advised to carefully check the icon itself to confirm how long the expiration date is.

Eyebrow tint is used to change the color of eyebrows. Choose a suitable eyebrow brush according to the length of eyebrows. If the eyebrows are naturally short, it is recommended to choose a spiral brush with a smaller head. In addition, short eyebrows are not easy to clump and are relatively neat. If the eyebrows are long, you can use a larger comb-shaped brush head. Put the eyebrow brush under the eyebrows and brush it gently against the growth direction of the eyebrows several times so that all the eyebrows are neatly curled up. Be sure to brush from the roots of the eyebrows. When you feel that it is almost the same, you can brush along the direction of the eyebrows. Be sure to pay attention to keep the brush direction consistent and don't mess up the eyebrows. After the eyebrows are fully brushed and neat, you can evenly apply some eyebrow tint to the eyebrows. Note: Don't apply too much on short eyebrows, just a little will make the eyebrows look more natural. Girls with long eyebrows can apply more in moderation. Then use the eyebrow brush to brush your eyebrows gently in the mirror until you feel satisfied.

The effect of eyebrow tint is one-time, unless you use semi-permanent eyebrow tint, which is more durable, but the color of general eyebrow tint needs to be removed. Eyebrow tint is a new eyebrow product, which was first spread from Korean idol groups. Its purpose is to change the color of eyebrows, a bit like hair dyeing, but there is still a certain gap and the method is different. However, the eyebrows of Korean idol groups are not created by eyebrow tint, and their colors are more durable, but they will also fade. The color of general eyebrow tint is not as many as that used by Korean idols, and they are generally earth tones.
