Overview
Cos De BAHA Salicylic Acid BHA 4% Serum (S4) is a 30ml potent exfoliating treatment featuring 4% salicylic acid for deep pore cleansing and acne prevention. This clinical-strength K-beauty serum combines niacinamide, aloe vera, and botanical extracts like rose damascena, lavender, green tea, and mugwort to dissolve blackheads, reduce inflammation, brighten tone, and smooth texture without excessive dryness. Its lightweight, water-like texture absorbs rapidly, making it perfect for oily, acne-prone skin in Bangladesh’s humid climate. Fragrance-free and non-comedogenic, it transforms congested pores into clear, refined complexion for Kioraa’s acne-fighting routines.
Key Benefits
- 4% salicylic acid penetrates pores to dissolve oil, dead skin, and blackheads.
- Niacinamide fades post-acne marks and regulates sebum production.
- Aloe vera soothes irritation while botanicals provide antioxidants.
- Reduces acne, whiteheads, and congestion with antibacterial action.
- Improves texture and minimizes pore appearance over time.
- Gentle enough for daily use without disrupting skin barrier.
Who It’s For
Essential for oily, acne-prone, blackhead-prone, or congested skin needing powerful BHA exfoliation, especially in Bangladesh’s humid pollution causing pore clogging. Perfect for teenagers with hormonal acne or adults battling adult acne. Makeup wearers will love the smooth, matte base that prevents shine without stripping moisture.
How It Works
Salicylic acid (4%) being oil-soluble penetrates sebum-filled pores to exfoliate from within, dissolving keratin plugs while exhibiting anti-inflammatory properties. Niacinamide boosts ceramide production and inhibits melanin transfer for even tone. Aloe barbadensis extract calms post-exfoliation sensitivity as green tea and botanicals provide antioxidants against free radicals. The low molecular weight ensures deep delivery for clearer, smoother complexion progressively.
How to Use
After cleansing/toner, apply 2-3 drops to face/neck evening routine, starting 3x weekly. Pat gently until absorbed; follow with moisturizer. Use SPF daytime mandatory. Build tolerance gradually. Pairs perfectly with Kioraa niacinamide serum for enhanced acne control and brightening.
