Besides water and fragrance, glycerin is one of the common ingredients in cosmetics with skin whitening effects. So to know if using glycerin is safe and effective, it is necessary to understand how this substance works.
1. Skin whitening glycerin Glycerin is also known as glycerol, a natural compound derived from vegetable oils or animal fats. Glycerin is a liquid substance, without color or odor, and is considered to be sweet like syrup. Glycerin is a substance that has the ability to hold moisture, pulling water into the outer layer of the skin from the deep layers of the skin and even the air. In skin care products, glycerin is commonly used with other humectants such as alpha hydroxy acids, hyaluronic acid, propylene glycol, sorbitol...
Recognized as a key ingredient in moisturizers and other lotions, the use of glycerin in its pure form is increasingly popular in the beauty industry. Studies have shown that glycerin can affect the skin in a number of ways such as:
Hydrate the stratum corneum of the skin; Strengthens the protective barrier and mechanical properties of the skin; Protects the skin from irritants; Promotes faster wound healing. Glycerin is best known for its ability to hydrate and protect the skin. Although not well known as a skin whitener, glycerin can help exfoliate the skin. Specifically, when applying glycerin, it will help the outer layer of the skin to be very moisturized, making the skin softer in the top layer, which will make it easier to exfoliate. When these dead cells are removed, the skin is brighter, minimizing the appearance of dark spots, scars and age spots.

2. Is glycerin safe? As a humectant, glycerin pulls water from the sources closest to the skin. Especially in low humidity conditions the closest source of water is from the deeper layers of the skin. This can cause the skin to become dehydrated and even blister. For this reason, it is best to dilute pure glycerin before using it on the face.
There are many advocates sharing that glycerin should be diluted with rose water to hydrate the skin and fill the pores. There are studies that have shown that rose water has a very positive antioxidant ability on the skin. In addition, the combination of glycerin, hyaluronic acid, and centella asiatica extract can help improve skin barrier function within 24 hours of application.
Although there are not too many reported side effects when using glycerin, but because it is a product of natural origin, allergic reactions on the skin and body can still occur. If the user encounters some skin conditions such as redness, rash, itching..., please stop using glycerin and see a dermatologist in case of need. Then, if you use another skin care product, you should carefully read the ingredient list and choose products that do not contain glycerin.
3. Conclusion Glycerin is considered an effective moisturizer and skin protectant in the beauty industry. However, with the effect of whitening the skin, glycerin is not a specialized substance for this purpose, although it also contributes to the better exfoliating process of the skin. Glycerin should be used properly and when there are any signs, should stop using and notify the doctor for timely treatment.
