Effaclar K

Effaclar K is a lightweight lotion, enriched with salicylic acid for acne prone skin. Effaclar K provides gentle exfoliation and creates a blemish-free complexion. Its active Ingredients are 15% salicylic acid and thermal spring water. Effaclar K is also an excellent make-up base. Effaclar K is also non-comedogenic, so it will not clog pores.

Effaclar K is clinically proven to be a highly effective and well-tolerated acne treatment. It provides deep exfoliation and is gentle enough for daily use. Effaclar K's terrific results are in large part due to La Roche Posay's exclusive patented LHA (lipohydroxy acid). LHA is a potent keratolytic, which helps control acne breakout. The innovative formula progressively refines skin texture, revealing healthy and glowing skin. Effaclar K is also formulated with naturally soothing La Roche-Posay Thermal Spring Water, which helps heal the skin.

Directions for Effaclar K:

Clean the skin thoroughly before applying. Cover the entire affected area with a thin layer 1 to 3 times daily. Because too much drying of the skin may occur, start with 1 application daily, then gradually increase to 2 to 3 times daily if needed or as directed by a physician. If bothersome dryness or peeling occurs, reduce application to once a day or every other day.
