Polylactic acid helps stimulate [collagen](https://lovi.care/skincare/au/ingredients/collagen) production in the skin to improve firmness and reduce the appearance of wrinkles. It acts gradually over time as a biocompatible filler to restore volume and smooth texture. ### How do you use polylactic acid? Polylactic acid is typically used as a professional dermal filler administered by a qualified practitioner to help stimulate collagen production and smooth wrinkles. Because it works gradually over a series of treatments, visible improvements may develop over several months. ### Should you use polylactic acid in the morning or at night? Polylactic acid may be used at either time of day depending on your routine and product instructions. It helps improve skin texture and firmness over time. ### Can you use polylactic acid every day? Polylactic acid is typically not used every day because it is a professional dermal filler or specialized treatment rather than a daily topical skincare product. ### Does polylactic acid cause purging or irritation? Polylactic acid is unlikely to cause purging, as it is not an exfoliating acid that accelerates cell turnover. ### Which skin types is polylactic acid best for? Polylactic acid helps exfoliate the skin and is found in the Caudalie Deep Cleansing Exfoliator. ## Brands with polylactic acid - French skincare: [Caudalie](https://lovi.care/skincare/au/brands/caudalie) ## About the Lovi Fit Lovi: Unbiased, science-based skincare AI trained on real user outcomes.
