La Roche-Posay Effaclar Duo+M 40 ml

La Roche-Posay Effaclar Duo+M is a daily anti-blemish moisturizer from the French dermatological brand, made for oily, acne-prone skin that also struggles with the marks breakouts leave behind.

It works on three fronts. Salicylic acid and LHA gently exfoliate inside the pore to clear clogs and prevent new spots. Niacinamide calms redness and supports the barrier. And the +M refers to its focus on the marks — the red and brown spots that linger after a breakout — alongside a microbiome-supporting complex. All in La Roche-Posay thermal spring water, with a light, matte finish.

How to use: apply to the whole face morning and evening after cleansing. Use sunscreen in the morning, because exfoliating acids increase sun sensitivity.

Size: 40 ml

Frequently asked questions

Can I use it as my only moisturizer?
For oily skin, usually yes. If your skin feels tight, add a light non-comedogenic moisturizer on top at night.

How long before I see results?
Many people see fewer active spots within a few weeks. Post-acne marks take longer — around 8 weeks of consistent use.

Can I use it with benzoyl peroxide or retinoids?
Yes, but introduce one active at a time and watch for dryness. If irritation appears, use Duo+M in the morning and the other treatment at night.
