Lactic acid for skin is one of the most effective pregnancy safe AHA options and an ideal exfoliant for sensitive skin. Many people exploring AHA skincare ask what does lactic acid do and how it improves texture without irritation. As a gentle AHA exfoliant, lactic acid supports barrier safe chemical exfoliation with alpha hydroxy acids while improving hydration and smoothness.
How lactic acid improves skin texture
Your skin naturally sheds dead cells through desquamation. When this slows, dead cells can build up and create rough texture, dullness, uneven tone, and reduced product absorption. Lactic acid gently loosens the bonds between these dead cells so they shed evenly, revealing smoother skin underneath.
Lactic acid supports hydration and barrier health
Lactic acid is also a humectant, meaning it attracts water into the skin. This helps improve hydration, support barrier integrity, and reduce the “tight” feeling some people associate with exfoliation.
Why lactic acid is used in pregnancy-safe skincare
During pregnancy and postpartum, skin can become more reactive. Lactic acid is commonly used as a pregnancy-safe exfoliation option because it refines texture gradually and supports hydration rather than stripping the barrier.
Where POLISH fits in
POLISH was formulated with lactic acid to refine texture while supporting barrier comfort. It pairs lactic acid with complementary resurfacing ingredients for gradual renewal.
