Lactic acid is a natural ingredient found in dairy products that has many beneficial properties in cosmetics. Chemically, it is an alpha-hydroxy acid that effectively exfoliates the skin, promoting cell renewal and giving the skin a radiant glow. Lactic acid not only softens and moisturizes the skin, but also helps reduce fine lines and even out skin tone. It is obtained naturally by fermenting milk sugar or can be synthesized in laboratories. This ingredient is a great choice for those who want healthier and younger-looking skin. By choosing products with lactic acid, you are not only taking care of your skin, but also getting a natural source of beauty that reveals the skin’s natural beauty.
Purpose and Benefits
Lactic acid is a true skincare treasure, capable of subtly transforming skin texture and appearance. One of its most impressive properties is its ability to balance the skin’s moisture level. It acts as a humectant, attracting water molecules to the skin and helping to keep it supple and soft. This is especially beneficial for owners of dry or dehydrated skin who need more intensive hydration. In addition, lactic acid has a gentle but effective keratolytic effect. It loosens dead skin cells and promotes their separation, leaving the skin looking smoother, brighter and healthier. Its action is gentle enough to suit even sensitive skin, yet effective enough to see noticeable results. This ingredient also helps to strengthen the skin’s protective barrier, maintaining a natural pH balance and reducing damage from external environmental factors. Lactic acid is also fascinating in its versatility. It is suitable not only for facial skin care – in hair care products it can help to balance the pH of the scalp, reduce dandruff and give hair more softness and shine. In this way, this acid becomes a valuable ingredient that can be used to care for not only the skin but also the hair. A special property of lactic acid is its ability to act as a bridge between pure nature and advanced chemistry. It is an ingredient that, combining gentleness and effectiveness, embodies the essence of modern cosmetics.
Security Information
Lactic acid, as a cosmetic ingredient, has a relatively safe profile, but caution is always recommended. While most people tolerate it well, some may experience mild irritation, especially those with sensitive skin. Allergic reactions are rare but possible, so it’s a good idea to do a patch test first before using new products with this ingredient. It is recommended to avoid using this acid in large quantities or in combination with other strong acids to prevent skin irritation. It is recognized worldwide as safe in the cosmetics industry, but laws may vary from country to country, so it is worth checking local regulations. When using products with lactic acid, it is recommended to do so gradually, monitoring the skin’s reaction and applying adequate hydration after application to maintain optimal skin comfort.
Sustainability and Extraction
The sustainability and ethics of lactic acid are important aspects that have significant implications for its use in cosmetics. This acid is most often obtained from natural sources such as milk, but it can also be synthesized in laboratories. Natural sources, if obtained from responsibly managed farms, may have a smaller ecological footprint, as less pollution and resources are used in their production. However, intensive milk production can harm the environment, causing soil erosion and water pollution. From a social perspective, it is important that workers receive fair wages and work in safe conditions. Thus, a sustainable source of lactic acid is one that relies on organic farming methods and ensures fair working conditions. When choosing products that use lactic acid, it is important to pay attention to the sources of suppliers and their social responsibility, as this can contribute to the development of a more sustainable cosmetics industry.
Products
There are many cosmetic products that contain lactic acid, and they span various categories for skin and hair care. Facial cleansers, such as the COSRX Low pH Good Morning Gel Cleanser and Innisfree Jeju Volcanic Pore Cleansing Foam, often include this ingredient to gently exfoliate the skin and provide moisture. Furthermore, moisturizers like the Etude House Soon Jung 2x Barrier Intensive Cream also appreciate the benefits of lactic acid, as it helps restore the skin barrier and provides softness. Peels, such as the Neogen Bio-Peel Gauze Peeling Green Tea, also frequently rely on this ingredient to achieve smoother and brighter skin. Even hair care products, like the Mise en Scene Perfect Serum, may contain lactic acid to improve hair texture and hydration.
