Second, glycerin as a special effect of skin care products 1, can whitening replenishment: honey glycerin mask (whitening replenishment)
1 teaspoon of honey, 1 teaspoon of glycerine, 2 tablespoons of water, mix well and serve as a high-quality facial mask. Apply lightly to the face and neck to form a thin film. Carefully remove the mask after 20-25 minutes. It can be used for normal, dry and faded skin, 1-2 times per week.
2, can be used for hand moisturizing:
Pour appropriate amount of White Glycerin into the water and put your hands together for warmth. Apply to the back of the hand and moisturize it. The effect is the same as the hand cream. Because glycerin absorbs moisture from the air to achieve skin moisture, it is more suitable for use in areas with humid air in the south. Of course, the north can also be used after diluting water.
3, can remove makeup:
There is no surfactant in the pure glycerin, can not emulsify some oily cosmetics, but glycerin dissolves in water, so with water, you can achieve remover effect.
4, can be used as a replenishing mask:
Soak facial mask paper in purified water (best in ice). After cleansing, apply a thick layer of glycerine on the face. Massage your fingers in circular light for three minutes to fully absorb it. Apply a good facial mask to the face. Take it in fifteen minutes, and then apply a little glycerin from the face to keep the face calm. After a few minutes, the glycerin is completely absorbed. The excellent replenishment effect will surprise you and you will become a water beauty. Make-up the next day will be a lot easier. This mask is non-irritating and can be used every night. You can also re-bubble the water of the mask paper to milk to nourish nutrients, or add whitening pearl powder in the water and other effects, can be used to properly reconcile their own skin.
5, can be used to moisturize body water:
During the bath, the face will be washed with a thick layer of glycerin, so that the entire body can fully absorb the damp air in the bathroom. After a few minutes, wash it off with clean water. After bathing, you will feel that the entire body is full of water, and the body relaxes and the skin does not dry.
6, can go to the eye fat particles:
The specific approach is to massage in the fat particles every night. In a few days, the fat granules are shelled. Although some pain, but insisted on massage for a week or so, and finally scarred and lost, but the face will not have scars!
Third, the use of glycerin to achieve the benefits of cosmetic skin care Note 1, dynamic moisturizing: glycerol absorption, and will not leave the release of water. The dynamic moisturizing can adjust the moisture according to the surrounding environment. If the skin contains less moisture, the moisturizer will release the absorbed water, and if there is more moisture in the skin, the moisturizer is no longer continuous. Absorb moisture. Like hyaluronic acid, betaine humectants can all be adjusted according to the moisture in the skin to release moisture. This not only can effectively moisturize, but also moderate skin feel. Glycerin does not have a dynamic moisturizing ability, so it is generally not recommended to use glycerin in places where the landscape is very dry. Since in this case, glycerol is likely to absorb water from the skin to reach its equilibrium.
2, if only use glycerin instead of body lotion, then it can not play a real moisturizing effect. The oil in the body lotion can form a film on the skin surface to prevent evaporation of water.
3. The glycerin that we usually buy is not 100%, but an aqueous solution of glycerol diluted with water. Because 100% glycerin feels too sticky.
Fourth, the correct use of glycerol can reach the best results with the least money:
1. Moisturizer: Aqueous glycerin can be used as a lotion, and because of the good safety of glycerin, many sensitive skins can be safely used. However, due to the aforementioned reasons, glycerin alone can not completely lock the moisture, so after the application of glycerin and then apply a layer of body lotion.
2, cracking hands and feet: In the autumn and winter season, many mm hands and feet need to crack, in addition to hand cream, you can also use glycerin. If allantoin can be added to glycerin, the anti-crack results are even better. In general, I would equip my office with a bottle of glycerin, wipe my hands at any time, and apply hand cream sooner or later. This winter is still very hand down.
3, anti-cracking of the lips: Many mm will buy lip balm, in fact, glycerin can also be used in the lips, and very results oh. But to be vigilant, it's best not to eat into your mouth.
