Based on Quassia extract, LSI researchers have developed a range of cosmetics specially designed for patients suffering from facial redness and rosacea.

QUASIX® products are based on the balanced combination of four active principles:

The plant extract of Quassia (Quassia amara) whose anti-parasitic, anti-microbial, anti-inflammatory and anti-oxidant properties have been amply demonstrated in the scientific literature.
Nicotinamide (Vitamin B3) is able to maintain and restore the integrity of the skin barrier, the natural protective of the epidermis.
Vegetable glycerin is a skin-friendly humectant, which helps maintain ideal hydration of the upper layers of the epidermis.
Sorbitol, a sugar which also helps to maintain the water balance of the epidermis.
The pH of QUASIX® products is 5.5, ideal for preserving the integrity of the functions of the skin barrier.

To date, the QUASIX® range consists of three products:

QUASIX® cream, for the management of skin redness and rosacea in combination and dry skin.
QUASIX® gel, for the management of cutaneous redness and rosacea in oily skin.
QUASIX® SPF 30 protective cream, which contains a high index mineral sunscreen, for the special needs of patients with facial redness and rosacea during hours of sun exposure, to protect the skin from harmful ultraviolet radiation .
