Lactic Acid

Why Lactic Acid Matters in Skincare

Lactic acid is an alpha hydroxy acid (AHA) known for delivering effective exfoliation while remaining gentle and hydrating. It works by loosening the bonds between dead skin cells, allowing them to shed naturally and revealing smoother, brighter, and more even-toned skin.

Unlike stronger AHAs, lactic acid also acts as a humectant, helping the skin attract and retain moisture. This makes it especially suitable for dry, sensitive, or mature skin. With regular use, lactic acid can improve skin texture, soften fine lines, reduce hyperpigmentation, and support a healthier skin barrier.

Because of its balanced performance, lactic acid is commonly found in exfoliating toners, serums, masks, and anti-aging formulations.

Where is Lactic Acid derived from?
Lactic acid can be naturally derived or synthetically produced for consistency. Common sources include:

  • Fermented milk (traditional source)
  • Fermented plant sugars (corn, beet, or sugarcane)
  • Synthetic fermentation for cosmetic-grade purity and vegan formulations

Bottom line: Lactic acid is a multitasking AHA that exfoliates, hydrates, and smooths — making it ideal for those who want visible results without harsh irritation.
