The world-famous Cleopatra used to apply egg whites on her face at night, and when they dried, they formed a taut film on her face, which she washed off with water in the morning to keep her skin smooth, delicate and youthful-looking. It is said that this is the origin of the modern popular mask. It seems that the easy to do and effective beauty mask was adopted by beauty loving ladies a long time ago and has been continuously improved and used to this day. To this day, facial masks are still a favorite method of maintenance for women. Most of the masks are cold to put on, but depending on the type of mask, the skin care effect is also different. Here I make the following classification for the common mask on the market, let us have a good understanding of the mask this popular maintenance products: 1, cream mask cream mask is a common type of mask, mostly in the form of bottles and jars packaging, squeeze out very much like a thick lotion, cream, generally can be put on 10 to 15 minutes after washing, mostly with moisturizing and nourishing effect. It is suitable for dry skin or for use in the autumn and winter seasons. If you do not add some acidic ingredients, skin metabolism ingredients, there is no limit on the number of times to use the cream mask. 2, clay-like mask clay-like mask mostly present powder or mud paste appearance, powder in the use of the need to add water blending, mud paste can be directly on the skin, the use of more convenient, the application time is also in 10 ~ 15 minutes. Clay-like masks usually contain kaolin, clay and other ingredients, mainly to play a deep cleansing, oil adsorption, exfoliation, suitable for oily skin, keratinous skin or spring and summer season. In addition, in terms of frequency of use, it should not be used excessively frequently because of its metabolic keratin and highly cleansing effects. Oily skin 1 to 2 times a week, dry skin every 2 to 3 weeks can be 1 time, so as not to cause a sense of irritation to the skin. 3, the membrane mask membrane mask, the use of a variety of materials, such as paper pulp, jelly, non-woven, bio-fiber, etc., these membrane-like mask with the maintenance function, depending on the essence of the composition of the mask, it is difficult to categorize. As this type of mask after the application, usually do not need to go through the cleaning process, so I want to remind everyone, do not put on the membrane mask, put on the application and fell asleep, put on the mask for too long is easy to cause skin sensitivity, irritation, dryness. 4, peel-off mask peel-off mask cleaning principle and clay-like mask the same, also by raising the epidermal temperature, promote blood circulation and metabolism. The main ingredients are polymer gum, water and alcohol, with few other ingredients. Since the peeling mask process needs to wait until the mask is dry to complete, no moisturizer can be added to the ingredients, which is not very suitable for dry skin, and sensitive skin is not very suitable due to the peeling action. The order of peeling should be from top to bottom. Pay special attention to avoiding the skin around the eyes, eyebrows, hairline and lips to prevent skin damage when peeling. 5, acne-specific T-shaped mask This type of mask is mostly peeling type, specifically to deal with the T-zone acne, there is a strong sticky suction, in the peeling will be large and small sebum acne peeled out, with the effect of removing deep acne. However, it is not suitable for allergic, dry, thin keratinized skin and septic skin because of its strong peeling power, and it should not be used frequently for oily and combination skin. This product is mainly used to seal the skin temporarily, so that the skin temperature is slightly increased, helping the skin to efficiently absorb the nourishing ingredients in the mask, so that you can often see the immediate effect after the application. However, it should be reminded that a mask is not a panacea. The frequency of use should be determined according to the function of the mask, not greedy to use more. And, after applying the mask, be sure to apply a lotion or cream with moisturizing and locking effect, so as to keep the mask ingredients in the skin for a long time and play a good nourishing effect.
