The Cos De BAHA S4 Salicylic Acid BHA 4% Serum is the definitive 2026 clinical-grade exfoliation solution for individuals seeking high-velocity eradication of stubborn acne, deep-seated blackheads, and persistent oil congestion. Engineered with a foundational high-potency 4% Salicylic Acid matrix (the strongest BHA exfoliant in the Cos De BAHA lineup) and a sophisticated soothing carrier, this professional-grade corrective serum provides a 3500V-level pore-clearing surge. It targets hyper-activated sebaceous glands—delivering an immediate reduction in surface sebum while biologically ensuring your skin barrier stays calm, hydrated, and free from micro-irritation.
Specifically, the formulation is fortified with niacinamide and a 72% organic Aloe Barbadensis leaf matrix. Consequently, it halts the inflammatory cycle to prevent future hormonal breakouts and minimize stretched pore walls. Furthermore, the inclusion of premium camellia sinensis (green tea) and artemisia (mugwort) extracts ensures a significant increase in antibacterial defense and localized redness relief. Therefore, the Cos De BAHA S4 Serum is the ultimate professional choice for achieving a smooth, high-performance, and perfectly clarified 2026 clinical complexion.
Key Features of Cos De BAHA S4 Salicylic Acid 4% Serum
Maximum Strength 4% BHA Exfoliation: First, it utilizes a concentrated lipid-soluble beta hydroxy acid. Specifically, it provides a 3500V-level oil-melting force that penetrates deep inside pore recesses to dissolve sticky dead skin cells, making it a safe-haven for those struggling with cystic blemishes.
72% Organic Aloe Vera Base: Additionally, this advanced formulation completely skips pure water as its main vehicle. Thus, it provides an instant biological buffer that minimizes the stinging, flaking, or dryness commonly associated with high-percentage acid peels.
Synergistic Niacinamide Barrier Protection: Moreover, it incorporates high-purity niacinamide. In particular, it targets oil production equilibrium, fade post-acne hyperpigmentation marks, and strengthens the skin’s defense layer against 2026 urban environmental stressors.
Blackhead & Whitehead Eradication: Regarding texture refinement, the serum actively loosens structural plug bonds within the follicle. As a result, it provides an immediate biological purging effect, forcing blackheads out and noticeably smoothing rough skin texture.
Botanical Anti-Inflammatory Loop: Furthermore, it is fortified with premium damask rose, lavender, and melissa extracts. Consequently, it works to calm active swelling, reducing overall facial redness and accelerating tissue recovery during high-velocity acne flare-ups.
Clean, 6-Free Certified Formula: Finally, it is designed without parabens, sulfates, alcohol, artificial colorants, gluten, or synthetic fragrances. Therefore, it preserves structural biological purity, ensuring compatibility with highly reactive, oily, and acneic skin profiles.
