La Roche Posay Effaclar Ultra Concentrated Serum with Salicylic Acid, Glycolic Acid, LHA+Soothing Niacinamide

Tri-Acid Complex • Pore Refining • Stubborn Blemish & Imperfection Control

La Roche-Posay Effaclar Ultra Concentrated Serum is an intensive leave-on chemical peeling treatment specifically formulated for adult acne-prone skin, persistent blemishes, and visible pores. Powered by a synergistic Tri-Acid Complex (Salicylic Acid, LHA, and Glycolic Acid) combined with soothing Niacinamide, this micro-exfoliating fluid targets stubborn breakouts, smooths skin texture, and fades post-acne marks.

Its non-greasy, fast-absorbing texture penetrates deeply to unclog pores and accelerate surface skin cell renewal without disrupting the protective moisture barrier.

Key Features & Beauty Benefits

• Tri-Acid Exfoliation: Combines AHA, BHA, and LHA to exfoliate skin surfaces and deep inside pore linings

• Unclogs & Tightens Pores: Clears trapped sebum, dead cells, and debris to visibly minimize enlarged pore appearance

• Fades Post-Acne Marks: Accelerates cellular turnover to clear dark spots, red marks, and uneven skin texture

• Anti-Recurrence Blemish Control: Helps break the cycle of recurring acne breakouts and blackheads

• Soothes & Hydrates: Infused with Niacinamide and Thermal Spring Water to reduce redness and offset exfoliation tightness

Core Active Ingredients & Functionality

• 1.5% Salicylic Acid (BHA): Oil-soluble acid that deeply unclogs pores and dissolves accumulated sebum and acne-causing debris.

• 3.5% Glycolic Acid (AHA): Water-soluble acid that gently peels away surface dead skin cells to restore radiance and refine texture.

• 0.45% LHA (Lipo-Hydroxy Acid): A gentle derivative of salicylic acid that micro-exfoliates skin surfaces with high precision and low irritation.

• Niacinamide (Vitamin B3): Calms inflammation, soothes redness, and reinforces the skin's protective lipid barrier.
