Maris Sal (Sea Salt)

Maris Sal, commonly known as sea salt, is obtained through the evaporation of seawater. It contains a variety of minerals and trace elements—such as magnesium, calcium, potassium, and sodium—that are valued for their skin-nourishing properties. In the cosmetics industry, sea salt is frequently used in skincare products to cleanse, exfoliate, and revitalize the skin.

Cosmetic Properties and Effects

Exfoliation: Sea salt is often used as a mechanical exfoliant. The fine salt crystals help remove dead skin cells, smooth the skin's surface, and promote cell renewal. This results in softer, more radiant skin.
Mineralizing: The minerals found in sea salt—such as magnesium, calcium, and potassium—help regulate the skin's moisture balance and strengthen the skin barrier. These minerals assist the skin in retaining moisture and promote healthy skin function.
Soothing and Healing: Sea salt possesses anti-inflammatory and healing properties. It can help alleviate skin irritation and inflammation, making it particularly beneficial for skin conditions such as eczema, psoriasis, and acne.
Stimulates Circulation: The use of sea salt products can improve blood circulation in the skin.

Improved blood circulation promotes the transport of oxygen and nutrients to skin cells, resulting in a healthier-looking complexion.

Use in Cosmetics

Sea salt is used in a wide range of skincare products, including:

Exfoliants: Body and facial scrubs containing sea salt remove dead skin cells, leaving the skin feeling smooth and refreshed.
Bath products: Bath salts and bath additives containing sea salt have a relaxing and nourishing effect. They can relieve muscle tension and revitalize the skin.
Cleansing products: Facial cleansers and soaps containing sea salt provide a deep cleanse and help remove impurities.
Masks: Sea salt face masks deeply cleanse and remineralize the skin.
Hair care products: In shampoos and hair care products, sea salt can help cleanse the scalp and boost hair volume.

Common combinations

Sea salt is often combined with other skin-nourishing and soothing ingredients to maximize its benefits:

Aloe vera: This combination provides extra hydration and soothes the skin.
Essential oils: Essential oils such as lavender or tea tree oil enhance the soothing properties of sea salt.
Plant extracts: Extracts like chamomile or green tea complement the anti-inflammatory and antioxidant effects of sea salt.
Hyaluronic acid: This combination delivers intense hydration and improves skin elasticity.

Safety and tolerability

Sea salt is considered safe and well-tolerated by most skin types. However, it may cause irritation on very sensitive skin or open wounds. It is recommended to use sea salt products with care and, if necessary, combine them with a soothing and moisturizing product. A patch test prior to the first application is recommended to rule out potential allergic reactions.
