Bringing back the popular topic from the last year: Ingredients, and the ingredient of today is Glycerin (Glycerol, Glycyl Alcohol).
The main properties of glycerin that are successfully used in the beauty industry are:
- Moisturizing. It absorbs moisture from the environment and ensures its penetration deep into the skin.
- Protection. It creates a layer, protecting the epidermis from the negative external factors. Glycerin is involved in the exfoliation of keratinized particles, making the skin smoother. It helps to get rid of acne and make the flaws less noticeable.
- Hypoallergenic. It doesn't provoke allergic reactions, flaking and irritation. Perfect for sensitive and thin skin.
- Lifting. It smoothes minor irregularities, helps to get rid of wrinkles.
- Good interaction with other ingredients. Due to its composition, glycerin acts as a stabilizer. It can improve the cleansing ability of other ingredients in the composition of products.
In terms of its moisturizing properties, Glycerin has been overtaken by Hyaluronic acid only. In skin care, its % should be no more than 5%. Greater concentration causes the opposite effect (dehydration).
Imagine a sponge that absorbs water. That's how the glycerin molecules work, drawing moisture to themselves. Molecules pull water from where the excess is: atmosphere or skin.
At a temperature of 20-250C and humidity of 45-65%, glycerin takes moisture from the air. In this case, it's good for the skin.
If temperature or humidity is lower, glycerin molecules will draw moisture from the skin, dehydrating it.
In summer, apply products with glycerin to slightly moist skin. In winter - no earlier than one hour before going outside.
