SEA WATER.

Valuable / HUMECTANT, SOLVENT

Sea Water, a naturally abundant source of essential minerals and trace elements, is a versatile skincare ingredient recognized for its multi-faceted benefits. Functioning as a skin-identical ingredient, it actively supports the epidermal barrier, enhances hydration, and calms inflammation, making it suitable for a wide array of skin concerns.

Science

Mechanism of Action

Rich in essential minerals such as magnesium, calcium, potassium, sodium, and zinc, along with trace elements like iodine and sulfur, Sea Water delivers diverse benefits to the skin. It works by soothing irritation and calming redness through its anti-inflammatory properties, including the attenuation of IL-1β induction and the reduction of allergic responses by decreasing IgE antibodies and inhibiting histamine. The magnesium content specifically strengthens the skin barrier, leading to improved moisture retention. Sea Water also offers gentle exfoliation, helps manage acne with antiseptic and antibacterial properties, balances oil production, and stimulates cellular metabolism to boost hydration, blood circulation, and luminosity. Dead Sea Water, in particular, promotes the production of vital skin barrier proteins (filaggrin, involucrin, transglutaminase) and calming beta-endorphins, utilizing a 'moderate ionic osmotic stress' (MIOS) mechanism to enhance epidermal barrier function and reduce inflammation.

Key findings

  1. 01 Significantly attenuated IL-1β induction by 46% and 54%, demonstrating potent inflammation inhibition.
  2. 02 A 15-minute bath treatment for 6 weeks greatly improved skin hydration, reduced roughness, and lessened skin redness in patients with atopic dry skin.
  3. 03 After four weeks, reduced skin roughness by 40.7% and boosted a better moisturizing effect.
  4. 04 Applied for 20 minutes several times over 2 weeks significantly decreased transepidermal water loss (TEWL) and increased skin capacitance in irritant contact dermatitis, suggesting inhibition of skin barrier disruption and dryness.
  5. 05 Reduced visible pores by 10% after 15 minutes of application.
  6. 06 Reduced dullness by 45% and improved luminosity by 45%.

Stability

Seawater for cosmetic use undergoes rigorous processing, including filtration and cold sterilization, to preserve its active components and eliminate impurities. Its mineral and salt concentrations are often meticulously adjusted to achieve an optimal isotonic balance suitable for skin cellular activity. It is frequently formulated with synergistic softening and soothing agents, such as red and brown algae extracts and vegetable glycerin. Deep Sea Water itself exhibits antimicrobial properties. Advanced delivery systems like nanosized minerals or liposomes are sometimes employed for Dead Sea Water to optimize efficacy and prevent potential antagonisms or precipitation with other active ingredients.

Synergies

  • Red and brown algae extracts for enhanced soothing
  • Vegetable glycerin for improved softening and hydration

Conflicts

  • Open wounds (risk of infection)
  • Excessive exposure or high concentrations can lead to skin dehydration and irritation, particularly for sensitive skin
  • Dead Sea Water may present antagonistic effects or cause unwanted precipitation with certain other active ingredients, sometimes mitigated by specialized delivery systems
