Improvement of skin appearance and rejuvenation of the skinGentle light therapy to promote collagen, elasticity and visibly improved skin appearance – without any invasive procedures.

Red light therapy has been used for many years by cosmetic institutes and dermatologists to naturally reduce the causes of skin ageing and improve the appearance of the skin. The light has a regenerative effect on the skin, increases natural collagen production and elastin synthesis as well as the metabolism of skin cells (fibroblasts), which can reduce wrinkles and improve the overall appearance of the skin.

Unlike invasive treatments such as chemical peels, microdermabrasion, microneedling or injections, light therapy does not damage the skin. The treatment is safe, painless and has no side effects when used properly. Skin activation is also used to improve the absorption of cosmetic active ingredients.

Firmer skin & fewer wrinkles

Fibroblasts (connective tissue cells) produce collagen, elastin and hyaluronic acid, which are responsible for the skin's tensile strength, elasticity and fullness. From the age of 25 onwards, the metabolism of fibroblasts slows down, causing the collagen content to decrease by an average of 1% per year. The red light is absorbed by the fibroblasts, where it increases the body's own production of collagen and elastin. This tightens the skin and reduces wrinkles and fine lines.

Reduction of pigment spots

Red light can help reduce the appearance of unwanted pigment spots and skin discolouration by regulating melanin production, thereby promoting the lightening of hyperpigmented skin. Areas of skin with too little pigment, on the other hand, are stimulated to produce the missing pigment.

Faster wound healing

The stimulation of regenerative and reparative processes in the skin contributes to accelerated wound healing. This effect is one of the most extensively researched effects of red light application and is therefore frequently used in the context of invasive skin rejuvenation procedures to shorten recovery times (‘social downtime’).

Reduction of skin blemishes & spots

Overproduction of sebum and blocked pores lead to blackheads and spots. Various studies show that red light and near-infrared light can reduce sebum production and inflammatory processes, thereby accelerating the skin's natural healing process. This leads to a reduction in lesions and an improvement in the appearance of the skin.

Improved tolerance to UV light

Red light helps improve the skin's antioxidant status, thereby reducing the unwanted side effects of UV light. At the same time, the desired effects are intensified by improved blood circulation and oxygen supply to the skin. That is why modern solariums now use red light in addition to UV light (‘hybrid light technology’).

Various studies have also shown that symptoms of skin diseases such as psoriasis, neurodermatitis and rosacea can be significantly reduced. However, the treatment of diseases should always be carried out in consultation with the attending physician.
