Bio-Chemical Rebalancing: How to Restore the Acid Mantle of an Irritated Scalp
Chronic pruritus and scalp flaking are symptoms of the destruction of the acid mantle — the hydrolipidic film with a pH of 5.5 that protects against fungi (Malassezia) and bacteria. Discover how sulfated surfactants in commercial shampoos alkalinize the skin and trigger inflammation, and how Silouel's Calming Treatment Shampoo restores homeostasis without chemical aggression.

Stimulating Neocollagenesis: The Pharmacological Synergy of HPR and Lipophilic Vitamin C
Epidermal turnover stagnates with age, and fibroblasts cease collagen synthesis. Discover how Hydroxypinacolone Retinoate (HPR) binds directly to nuclear receptors RXR/RAR without enzymatic conversion — without dermatitis — and how its synergy with Ascorbyl Tetraisopalmitate provides the mandatory co-factors for assembling the type I collagen triple helix.

Comparative Clinical Study: Rosemary Oil vs Minoxidil in Hair Loss
Follicular congestion with sebum and scales induces hypoxia at the bulb level, shortening the hair growth phase. Discover how the double-blind study by Panahi et al. (2015) demonstrated that rosemary oil generates hair strand growth equivalent to Minoxidil 2%, but with significantly less pruritus — and how Silouel's Rosemary Mint Scalp Refresh Scrub applies this biphasic protocol.

Treating Comedones: The Efficacy of Salicylic Acid and Niacinamide in Adult Acne
Adult female acne has a complex hormonal etiology: hyperseborrhea and follicular hyperkeratinization that block pores. Discover how Salicylic Acid BHA, the only lipophilic hydroxy acid, dissolves sebum plugs from within, and how its synergy with Niacinamide reduces lesions by up to 60-70% according to clinical trials.

Reconstructing the Stratum Corneum: The Clinical 3:1:1 Ratio for Ceramides NP, AP, and EOP
Barrier collapse causes erythema, flaking, and massive water loss (TEWL).
