Soaps, moisturisers or serums—there is one thing that is common in all, and that is glycerin. Besides skincare products, it is also widely used in its pure form to reduce dark spots, acne scars, birthmarks or any other pigmentation issues. Interestingly, many people also turn to cosmetic treatments or skin-bleaching products for the same, but these methods can be expensive and may not always deliver the desired results. Moreover, certain bleaching agents can irritate the skin, leading to redness, stinging, and itching. Here, glycerin emerges as a magic bullet which is natural and cheap. But does it really work?What Is Glycerin?Glycerin is a type of carbohydrate known as sugar alcohol or a polyol. This odorless liquid has a sweet taste and a syrupy consistency. While glycerin occurs naturally in plants through the fermentation of sugars, most of the glycerin nowadays is produced from the hydrolysis of fats and oils. Besides this vegan version, glycerin is also made from tallow (beef or mutton fat) through a process of hydrolysis. Can Glycerin Lighten Skin?Before we answer that question, it is important to understand how it benefits the skin. Glycerin is a humectant, meaning it attracts and retains moisture, making it an expert in hydration. It is also an emollient, which helps smooth rough or dry patches, especially in individuals with conditions like eczema or psoriasis. Additionally, glycerin has antimicrobial properties, offering some protection against harmful bacteria. It is also believed that glycerin can promote wound healing. However, more research is needed to establish the same. Can Glycerin Lighten Skin?Despite claims that glycerin can whiten skin, there is little scientific evidence to support this notion. Its primary function is to hydrate and protect rather than alter pigmentation. There is a high probability that glycerin's whitening claims might stem from its mild exfoliating properties. By keeping the outer layer of skin hydrated, glycerin makes it easier to remove dead skin cells, potentially brightening the complexion and improving the appearance of dark spots over time.How To Use Glycerin For SkincareWhile glycerin alone is beneficial for moisturizing and exfoliating, some individuals mix it with other ingredients, such as lemon juice and rose water, to enhance its effects. Here is a DIY Glycerin serum that you can make at home to experience its best results. FSteps To FollowMix 5 drops of pure glycerin with the juice of one lemon and 20 ml of rose water.Store the mixture in a small spray bottle.Apply daily using a cotton pad or mist it onto the skin after makeup application.Store in the refrigerator for freshness.Is Glycerin Safe For Skin?Glycerin is generally safe and widely used in cosmetic products. However, it can cause irritation, particularly for those with sensitive skin and allergies. As a precautionary measure, you can do a patch test. Apply a small amount to your skin and wait 24 hours to check for reactions such as redness, itching, or swelling. Also, you can be a little cautious with lemon juice as it can make the skin more sensitive to sunlight, increasing the risk of sunburn. Avoid sun exposure immediately after application.
