🔒 100% Authentic Collistar – sourced from authorised distributors, backed by our Money Back Guarantee.
Salicylic acid and succinic acid in one serum — the two work differently enough to justify both. Salicylic exfoliates inside the pore; succinic acid is antibacterial and pushes down inflammation. The formula is clear, settles fast, and doesn't leave skin tight or angry.
Three to five drops, morning or night, on clean skin before moisturiser. Start twice weekly if your skin's new to acids, move to daily once it's settled. Skip if you're already using a retinoid at night — let one active lead.
