Product summary

"La Roche-Posay - Effaclar K" is effective for: Anti-blemish and Exfoliation

This product could be helpful for: Moisturizing, Evens skin tone and Anti-aging, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • Salicylic acid (1.10% - 1.60%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.
  • Humectants (carnosine 0.30% - 0.70%, sarcosine 0.85% - 1.25% and zinc pca 1.00% - 1.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.


The product retails for 30.49A$ in Australia and from 13.79£ up to 20.00£ in the United Kingdom.
