1.Salicylic Acid (�-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-a.
� 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.
