A multi-action serum ideal for blemish-prone skin. La Roche-Posay’s best-selling Effaclar Ultra Concentrate Serum is a gentle yet effective formula that visibly clarifies the complexion, while micro-exfoliating the skin to decongest the pores and buff away dead surface cells.

Featuring salicylic, glycolic and lipo-hydroxy acids, the concentrated serum boasts optimal results, encouraging smoother-looking skin and a diminished appearance of imperfections. The formula is enriched with the brand’s thermal spring water and niacinamide, providing soothing and brightening benefits, alongside promoting a mattified finish to reduce the look of excess shine.
