Formulated to boost skin's immune system, this serum helps to strengthen and protect skin against all aggressions (UV rays, pollution, cigarette smoke, fatigue). Loved by skin that's easily upset. 

Boasting both anti-aging and revitalizing benefits, Le Booster PROTECTION works to protect your skin against external AND internal stresses while helping to boost its immune defenses. Over time, your skin's ability to adapt is improved and its balance stabilized.

Mix it with La Crème du Jour and/or La Crème du Soir if your skin is prone to breakouts, or apply directly to spots if they only appear occasionally.
