The science behind Dead Sea products and their unique properties

1) What is special about the mineral composition of the Dead Sea and what does science say?

The Dead Sea is considered a unique source of minerals due to its exceptionally high salinity and ionic composition different from regular seawater. Chemical studies of saline solutions show that the Dead Sea contains significant concentrations of magnesium, calcium, potassium, sodium, bromides, and chlorides. Products based on Dead Sea water, salt, or mud utilize this mix to affect skin feel, moisture, and the temporary appearance of smoother texture, primarily due to the water-binding potential and osmotic effect of salts.

• Magnesium may contribute to the sensory soothing of sensitive skin.
• Calcium and potassium are related to skin barrier balancing processes and a sense of elasticity.
• Bromides, are known to have a calming effect on skin contact for some people.

2) Osmosis and humidity, why salt can both dry and help

The science behind salt on the skin is based on the principles of osmosis. Salt solutions attract water, so in too high a concentration they can cause dryness or burning, especially on chapped skin. On the other hand, in balanced cosmetic formulations, combined with humectants like glycerin and hyaluronic acid, minerals can support improved moisture retention on the skin’s surface and help it look fresher.

• In mild concentrations, salts can provide a "toner" and temporary firming sensation.
• At concentrations that are too high, the risk of dryness increases, so it is important to follow instructions for use.
• Combining with emollients, oils or ceramides reduces dryness and enhances comfort.

3) Dead Sea mud, particle structure and fat and dirt adsorption

Dead Sea mud is a mixture of minerals and organic matter, with fine particles that can adhere to the surface of the skin and absorb excess sebum and dirt. This mechanism is similar to clay masks, but the mineral composition provides a different texture and experience. When the mud dries, it creates a slight tightening effect, and after rinsing, many users report a feeling of cleanliness and smoothness.

• A mud mask can be suitable for oily or combination skin, especially in the T-zone.
• For dry skin, it is best to shorten the leave-in time and finish with a rich cream.
• It is recommended to avoid aggressive rubbing when removing to avoid irritating the skin.

4) Effect on the skin barrier, why minerals are important

The skin barrier is made up of stratum corneum, lipids, and organized skin cells, which aim to prevent water loss and protect against irritation. Certain minerals indirectly participate in biological processes in the skin and the sense of balance, but it is important to understand that a cosmetic product does not "fix" a barrier like a medical treatment. What it can do is support a more comfortable environment for the skin, reduce the feeling of dryness, and provide a user experience that promotes persistence in a skin
