If the Glycolic Acid serum is for surface glow, the Guerniss Raw Salicylic Acid 0.5% Serum is your "deep cleaner." This is a Beta Hydroxy Acid (BHA), which is oil-soluble—meaning it can actually get inside your pores to clear out gunk.
At a 0.5% concentration, this is a very gentle, beginner-friendly formulation. It’s effective for daily maintenance without being as harsh as higher-percentage clinical peels.
Key Benefits
Deep Pore Cleansing: Penetrates oil buildup to dissolve sebum and dead skin cells that cause breakouts.
Blackhead & Whitehead Reduction: Specifically targets "plugged" pores to clear existing congestion and prevent new ones.
Anti-Inflammatory: Helps calm the redness and swelling associated with active acne.
Oil Control: Regulates excess surface oil, giving the skin a more matte finish throughout the day.
How to Use It Correctly
Cleanse: Start with a clean face.
Target or All-Over: You can apply a few drops to your entire face if you are oily, or use it as a spot treatment only on breakout-prone areas (like the chin or nose).
Frequency: Start using it 2–3 times a week. If your skin handles it well, you can move up to once daily.
Wait Time: Let it sink in for about a minute before applying your moisturizer.
