Red light is visible to the human eye and mainly affects the superficial layers of skin and tissue. It is particularly suitable for skin applications and supporting regenerative processes close to the surface. Near-infrared light, on the other hand, is invisible and penetrates much deeper into the tissue, where it can support cellular processes. Both types of light complement each other well and are specifically combined in heilys devices.

Our devices are developed and tested to meet high safety and quality standards. Development and testing take place in Germany, and the products comply with current safety requirements for domestic use. As lighting experts, we are intensively engaged in researching the relationship between light and health. Based on current studies, we develop targeted applications that combine safety and effectiveness.

Stick to the recommended intervals and application times of around ten to twenty minutes per irradiated area and use the device three to five times a week as a rule.

Results may vary greatly from person to person. Some users report noticeable effects after just one application, for example in terms of relaxation or pain relief. Other effects, such as improvements in skin appearance or general regeneration, often develop over several weeks of regular use. In order to realistically assess the effect, you should use the product consistently and regularly within the 30-day return period.
