1.Salicylic Acid (β-Hydroxy Acid)
• Keratolytic activity: It reduces corneocyte cohesion by breaking desmosomal proteins in the stratum corneum, promoting exfoliation of keratinized cells.
• Comedolytic effect: Penetrates into sebaceous follicles due to lipophilic nature and dissolves sebum plugs within pores.
• Anti-inflammatory action: Inhibits cyclooxygenase (COX-1) pathway and reduces lowering inflammatory mediators.
• Antimicrobial environment: Helps suppress proliferation of Cutibacterium acnes by reducing follicular occlusion.

2. Nicotinic Acid / Niacinamide (Vitamin B3)
• Sebostatic effect: Down-regulates sebaceous gland activity.
• Barrier repair: Stimulates synthesis of ceramides, free fatty acids, and cholesterol, strengthening the epidermal barrier.
• Anti-inflammatory activity: Inhibits inflammatory cytokines such as IL-1, IL-6, and TNF-α.
• Pigmentation control: Blocks melanosome transfer from melanocytes to keratinocytes.

3. Azelaic Acid
• Antimicrobial effect: Inhibits protein synthesis in Cutibacterium acnes and Staphylococcus epidermidis.
• Anti-keratinization: Suppresses abnormal keratinocyte proliferation, preventing comedone formation.
• Sebum regulation: Inhibits 5-alpha reductase, reducing conversion of testosterone to DHT and decreasing sebaceous activity.
• Depigmenting effect: Inhibits tyrosinase enzyme, decreasing melanin synthesis.
• Anti-inflammatory: Reduces ROS production

4.Allantoin
• Keratolytic and epithelial stimulation: Promotes shedding of dead cells and stimulates proliferation of epithelial tissue.
• Wound healing: Enhances fibroblast proliferation and extracellular matrix formation.
• Anti-irritant effect: Reduces inflammatory mediators

⁠5. Hyaluronic Acid
• Humectant activity: High molecular weight polysaccharide capable of binding up to 1000 times its weight in water.
• Barrier protection: Forms a viscoelastic film on the skin surface, preventing trans epidermal water loss (TEWL).
• Cell signaling: Interacts with CD44 receptors on keratinocytes, promoting wound healing

6. D-Panthenol (Pro-Vitamin B5)
• Conversion to pantothenic acid: Inside skin cells, panthenol converts to vitamin B5, which participates in Coenzyme-A synthesis.
• Barrier repair: Enhances lipid synthesis in epidermis, strengthening skin barrier.
• Humectant effect: Attracts and retains water in the stratum corneum.
• Anti-inflammatory activity: Reduces erythema, irritation, and itching.
