Let's be honest about what Lactic acid can really do, and what it can't.

What is Lactic acid

Lactic acid is a gentle AHA that exfoliates while also hydrating the skin.

How Lactic acid helps for blackheads

Blackheads are open pores filled with oxidised sebum that darkens in air. Lactic acid approaches the problem from a different angle: lactic acid is a gentle AHA that exfoliates while also hydrating the skin. As a result, used consistently, it gently improves the skin for blackheads.

How to use it

  • Cleanse with a gentle, non-stripping product.
  • Apply lactic acid to dry skin, starting 2–3 times a week.
  • Seal with a moisturiser to support the barrier.
  • Always use SPF 30+ in the morning.

Precautions
