Science

Sea Silt operates by deeply purifying the skin, facilitating the elimination of dead cells and impurities while enhancing oxygenation to stimulate cellular regeneration. It provides gentle exfoliation and anti-seborrhoeic action to minimize pore clogging, potentially ameliorating conditions such as acne and rosacea. Its rich mineral composition, including magnesium, zinc, calcium, and potassium, supports improved skin elasticity, hydration, and barrier function, concurrently stimulating collagen production. Additionally, its antioxidant properties, attributed to elements like selenium, defend against environmental damage and free radicals.

Key findings

  1. 01 Clinical studies on healthy volunteers (aged 22-29) demonstrated significant anti-inflammatory effects and the normalization of key skin parameters, including stratum corneum hydration, transepidermal water loss (TEWL), skin surface pH, and sebum content, when formulated in topical creams and lotions.

Not commonly dusted

Not applicable; Sea Silt is typically incorporated as a complex natural ingredient in formulations such as masks, cleansers, or creams, rather than as a highly concentrated isolated active where low-percentage dusting would be a concern.
