Lactic Acid

Lactic Acid

Lactic acid is a beloved ingredient in the skincare community, known for its gentle yet effective exfoliating properties. But what exactly is lactic acid, how does it work, and what products can you find it in? Let’s explore the magic of lactic acid in simple terms.

What Is Lactic Acid?

Lactic acid is an alpha hydroxy acid (AHA) that is derived from milk, although it can also be synthesized. It’s a water-soluble compound that is used in skincare for its exfoliating, hydrating, and anti-aging benefits. Unlike some other AHAs, lactic acid is known for being gentler on the skin, making it suitable for a variety of skin types.

How Does Lactic Acid Work?

Lactic acid works by breaking down the bonds between dead skin cells, allowing them to be easily removed from the skin’s surface. Here’s how it benefits your skin:

  1. Exfoliation: Lactic acid gently exfoliates the skin, removing dead skin cells and promoting cell turnover.
  2. Hydration: It acts as a humectant, drawing moisture into the skin and keeping it hydrated.
  3. Brightening: Regular use of lactic acid can help fade dark spots and even out skin tone, leading to a brighter complexion.
  4. Improves Texture: By promoting the shedding of dead skin cells, lactic acid helps to smooth and soften the skin’s texture.
  5. Anti-Aging: Lactic acid stimulates collagen production, which can reduce the appearance of fine lines and wrinkles.

What Products Is Lactic Acid Found In?

Lactic acid is a versatile ingredient that can be found in various skincare products aimed at exfoliating and hydrating the skin. Here are some common types:

  • Cleansers: Lactic acid cleansers help to gently exfoliate and cleanse the skin, removing impurities and dead skin cells.
  • Exfoliators: Products like exfoliating pads, scrubs, and peels often contain lactic acid to slough off dead skin cells.
  • Serums: Lactic acid serums provide a concentrated dose of the ingredient to target specific skin concerns.
  • Toners: Toners with lactic acid can help balance the skin’s pH while providing gentle exfoliation.
  • Moisturisers: Some moisturisers include lactic acid to enhance hydration and improve skin texture.
  • Masks: Face masks with lactic acid provide an intensive treatment to exfoliate and brighten the skin.

How Is Lactic Acid Made?

Lactic acid can be derived from natural sources or synthesized in a lab:

  1. Natural Extraction: Historically, lactic acid was obtained from sour milk. Today, it is often derived from the fermentation of carbohydrates such as glucose, sucrose, or lactose by certain bacteria.
  2. Synthetic Production: Lactic acid can also be synthesized in a lab to ensure high purity and consistency, which is ideal for use in skincare formulations.
