The science of NAD+

The science explained

A gold-standard corrective moisturiser for oily, blemish-prone skin that needs results without compromise. La Roche-Posay Effaclar Duo+M is designed to visibly reduce breakouts, blackheads, and post-acne marks while maintaining hydration and skin comfort. With fast-acting results and long-term prevention, this is a staple for clients who want clearer, more balanced skin without stripping or irritation.

This multi-target treatment works across all stages of acne, from active breakouts to post-inflammatory marks. Powered by salicylic acid, it gently exfoliates to unclog pores and reduce congestion, while niacinamide helps calm inflammation and improve overall skin tone. The addition of Phylobioma technology supports the skin’s microbiome, targeting the root causes of recurring breakouts and helping prevent future flare-ups. Clinically shown to deliver visible results in as little as 8 hours, it provides 24-hour hydration while reducing imperfections and improving skin clarity over time. Suitable for face, chest, and back, and ideal for both teenagers and adults with persistent or hormonal breakouts.
