The Science behind Lactic Acid: Benefits and Risks Explained

Lactic acid: A natural ingredient fundamental to skincare

Lactic acid is a popular ingredient in skincare that is known for its ability to exfoliate dead cells and improve the overall texture of the skin. It is derived from milk, vegetables, and fruits, and is a key component of the human body’s metabolism. This acid is a type of alpha-hydroxy acid (AHA) that is naturally produced in our bodies during exercise or when we are stressed. When used in a controlled concentration in skincare products, it can provide multiple benefits to the skin.

What is lactic acid?

Lactic acid is a type of AHA commonly found in skincare products. It is made from the fermentation of milk, vegetables, and fruits. This acid is used to exfoliate the top layer of the skin, removing dead skin cells, and promoting cell regeneration. Moreover, lactic acid is known for its hydrating properties. It can attract and retain moisture, making it an excellent ingredient for dry and sensitive skin types.

What are the benefits of lactic acid for skin?

Lactic acid has numerous benefits when used as an ingredient in skincare products. Some of these benefits include:

• Exfoliation: Lactic acid works by breaking down the bonds between dead skin cells and the surface of the skin. This allows for the removal of dead skin cells, revealing fresh, youthful-looking skin.
• Hyper-pigmentation: Lactic acid is found to be beneficial in the reduction of hyper-pigmentation, age spots, and sun spots.
• Anti-aging properties: Lactic acid is a natural moisturizer that can improve the appearance of fine lines and wrinkles by stimulating collagen production.
• Acne Treatment: Lactic acid helps to regulate sebum production making it beneficial for acne-prone skin.
• Skin texture: With regular use, lactic acid can improve the texture of the skin, making it smoother and brighter.

How to use lactic acid in your skincare routine?

Lactic acid is available in various concentrations and formulations, including serums, cleansers, peels, and masks. It is important to note that lactic acid is an AHA and should be used with care. Always do a patch test to check sensitivity to the product. Start with a lower concentration product and gradually increase usage until your skin adapts to the product. Additionally, always apply an SPF after using an AHA product as they can cause the skin to be more sensitive to the sun’s harmful rays.
