Well-hydrated skin is more comfortable, more radiant, and visibly more resistant to daily stressors.

With Hydra 4Ha™, Sothys Research has developed an expert response combining four sources of hyaluronic acid with two patented active ingredients to provide complete hydration.

The range acts on several levels to immediately hydrate the skin, preserve its moisture balance, and maintain lasting hydration throughout the day. Serums, creams, and a mask make up a complete ritual suitable for skin lacking moisture, regardless of its type or age.

Inspired by professional Sothys protocols, Hydra 4Ha™ helps the skin regain comfort, suppleness, and bounce. Sensations of tightness diminish, the complexion looks fresher, and the skin reveals a visibly plumped appearance.

In the salon as well as at home, Hydra 4Ha™ meets the needs of dehydrated skin through expertise that combines scientific performance, sensoriality, and professional application techniques.

Who is the Hydra 4Ha range for?

Hydra 4Ha™ is suitable for all dehydrated skin, whether dry, combination or oily, as long as it lacks water and comfort.

What is the difference between dry skin and dehydrated skin?

Dry skin naturally lacks lipids, while dehydrated skin lacks water. All skin types can be affected by dehydration.

Why is Hydra 4Ha different from other hydrating treatments?

The range combines four forms of hyaluronic acid with two Sothys patented active ingredients to provide immediate and long-lasting hydration, while helping the skin preserve its water balance.

How do you incorporate Hydra 4Ha into your beauty routine?

Hydra 4Ha™ fits into a daily routine adapted to the skin's hydration needs. The hydrating ampoule and then the Intensive Hydrating Serum are applied before the cream, chosen according to the skin's nature and needs, while the mask can occasionally complete the ritual for extra comfort.

A diagnosis carried out by a Sothys beautician helps select the most suitable treatments and complete the routine with a professional salon treatment.
