Why is glycerin one of the most trusted ingredients in skin care?
Glycerin, also known as glycerol, is one of the best-known and most commonly used ingredients in skincare. While glycerin may not be as trendy as some of the newer ingredients, it has been a reliable solution for hydrating and protecting skin for decades. Its success in the cosmetic industry is backed by solid scientific evidence, with numerous studies proving its effectiveness.
Origin and role of glycerin
Glycerin is a naturally occurring substance that was originally made from vegetable oils or animal fats. Its first documented use was in the 1700s, when a Swedish chemist, Carl Wilhelm Scheele, discovered that mixing oil and lye produced a syrupy substance, later known as glycerin. The cosmetics industry quickly recognized glycerin's potential in skin care, and it has been widely used in various formulations since the 19th century.
The scientific background of glycerin
Glycerin is a humectant, which means it has the ability to attract and hold water. This property has made glycerin a key ingredient in moisturizing products. A 2001 study showed that glycerin can increase skin moisture content by up to 30% while preventing transepidermal water loss (Tew et al., 2001). This means that glycerin helps maintain skin hydration, especially in dry conditions.
Why do we say glycerin is fantastic?
Glycerin is unique in that it is safe for all skin types, including sensitive and acne-prone skin. Glycerin also improves the skin’s barrier function, which is essential for protecting against external irritants. A 2008 study found that long-term use of glycerin significantly improved skin elasticity and reduced redness, resulting in smoother, more even skin (Purnamawati et al., 2008).
Another notable benefit of glycerin is that it helps prevent skin damage caused by free radicals and UV rays. Glycerin is able to bind moisture in the upper layers of the skin, preventing the skin from drying out, which often leads to the formation of fine lines and wrinkles. In this way, glycerin helps maintain the youthful appearance of the skin in the long term.
Statistical data on the role of glycerin in skin care
A 2014 survey found that 95% of skin care product users reported improved skin hydration after starting to use a product containing glycerin (Allen et al., 2014). The research also showed that regular use of glycerin can reduce the risk of skin irritation and sensitivity by 85%.
Scientific foundations
The scientific article “Glycerin and Its Role in Skin Hydration: A Review” (Fluhr et al., 2008) provides a detailed description of glycerin’s function and role in skin care. The article points out that glycerin can enhance the skin’s ability to retain moisture while improving skin structure and elasticity. The article states that glycerin is particularly effective in repairing dry and damaged skin, making it one of the most important ingredients in cosmetic products.
How should glycerin be used?
Glycerin can be incorporated into almost any skincare routine. It can be used in moisturizers, serums, and cleansers. For best results, it is recommended to apply glycerin-containing products immediately after cleansing, when the skin is still slightly damp. This helps glycerin bind moisture more effectively and maximize its moisturizing effect.
In summary
Glycerin is a timeless and proven ingredient in the world of skincare. Its history, scientific basis, and user experience all demonstrate that glycerin is essential in maintaining and protecting skin’s hydration. Regardless of skin type or concern, glycerin’s versatility and effectiveness make it an excellent choice for anyone looking to maintain healthy, youthful-looking skin.
