INCI Name: Lactic Acid Common Terms: Alpha-Hydroxy Acid (AHA) Nicknames: None
Lactic acid is an alpha-hydroxy acid (AHA) that is commonly used in cosmetic formulations as an exfoliant and skin brightener. It works by breaking down the bonds between dead skin cells, allowing them to be easily removed from the surface of the skin. This helps to improve skin texture and tone, reduce the appearance of fine lines and wrinkles, and promote a more youthful, radiant complexion. Lactic acid is also known for its moisturizing properties, as it helps to attract and retain water in the skin, leaving it feeling soft and hydrated. Additionally, it has antimicrobial properties that can help to prevent acne and other skin infections. Overall, lactic acid is a versatile ingredient that can be used in a wide range of cosmetic formulations to improve the appearance and health of the skin.
Lactic acid is a type of alpha-hydroxy acid (AHA) that is commonly used in skincare products. It works by exfoliating the skin's surface, which helps to remove dead skin cells and promote cell turnover. Lactic acid is also a humectant, which means it helps to attract and retain moisture in the skin. This can help to improve skin hydration and reduce the appearance of fine lines and wrinkles. Additionally, lactic acid has been shown to have antimicrobial properties, which can help to reduce the growth of acne-causing bacteria on the skin. Overall, the physical properties of lactic acid make it an effective ingredient for improving skin texture, hydration, and overall appearance.

Lactic acid is a common ingredient in many skincare products due to its exfoliating and moisturizing properties. However, it is important to note that it can cause some side effects and sensitivities in certain individuals. One of the most common side effects of lactic acid is skin irritation. This can manifest as redness, itching, or burning sensations on the skin. Individuals with sensitive skin or those who have never used lactic acid before may be more prone to experiencing these side effects. Lactic acid can also increase the skin's sensitivity to sunlight. This means that individuals who use products containing lactic acid should be diligent about wearing sunscreen and avoiding prolonged sun exposure. In addition, lactic acid can potentially interact with other ingredients in skincare products. For example, it should not be used in conjunction with retinol or other exfoliating agents, as this can cause excessive dryness and irritation. Overall, while lactic acid can be a beneficial ingredient in skincare products, it is important to be aware of its potential side effects and sensitivities. Individuals with sensitive skin or those who are unsure about using lactic acid should consult with a dermatologist before incorporating it into their skincare routine.
Lactic acid is a naturally occurring organic acid that is found in many foods, including dairy products, fruits, and vegetables. It is also produced by the human body during exercise and metabolism. However, the lactic acid used in many industrial applications, such as food and pharmaceuticals, is often produced through a fermentation process using bacteria such as Lactobacillus. This process involves the conversion of sugars into lactic acid by the bacteria. The resulting lactic acid can be purified and used in various applications. Lactic acid can also be synthesized chemically, but this is less common due to the availability of natural sources.
Lactic acid has a relatively low safety rating score according to the EWG Skin Deep database, with a score of 3 out of 10. This indicates that it has a moderate level of concern for potential health hazards. However, it is important to note that lactic acid is a naturally occurring substance in the body and is generally considered safe when used in cosmetic and personal care products at low concentrations. Other sources, such as the Cosmetic Ingredient Review Expert Panel, have also deemed lactic acid to be safe for use in cosmetics. Overall, while lactic acid may have some potential risks, it is generally considered safe when used appropriately.
Lactic acid is a naturally occurring organic acid that is commonly used in the food, pharmaceutical, and cosmetic industries. It is produced through the fermentation of carbohydrates by lactic acid bacteria, and is commonly found in dairy products such as yogurt and cheese. From an environmental perspective, the production of lactic acid can have both positive and negative impacts. On the one hand, the fermentation process used to produce lactic acid is a natural and sustainable process that does not require the use of fossil fuels or other non-renewable resources. Additionally, lactic acid is biodegradable and does not persist in the environment, making it a more environmentally friendly alternative to other synthetic acids. However, the production of lactic acid can also have negative environmental impacts if not managed properly. For example, the fermentation process can produce large amounts of wastewater that may contain high levels of organic matter and nutrients, which can contribute to water pollution if not properly treated. In terms of ethical sourcing practices, lactic acid is generally considered to be a safe and ethical ingredient. However, it is important to note that some lactic acid may be derived from animal sources, such as whey or other dairy products. In these cases, it is important to ensure that the animals are treated humanely and that their welfare is prioritized. Overall, lactic acid is a versatile and useful ingredient that can be produced in an environmentally sustainable and ethical manner. By choosing products that use lactic acid as an ingredient, consumers can support more sustainable and responsible production practices.
In conclusion, lactic acid is a versatile ingredient that serves various functions in the food, cosmetic, and pharmaceutical industries. Its production through fermentation is a natural and sustainable process. Lactic acid has numerous benefits, including its ability to improve skin texture, reduce wrinkles, and enhance the flavor and shelf life of food products. However, excessive consumption of lactic acid may cause digestive issues, and its use in high concentrations in skincare products may cause skin irritation. Lactic acid is found in various natural sources, including milk, yogurt, and fermented vegetables. Overall, lactic acid is a safe and effective ingredient when used in moderation and with proper precautions.
