A tanning lamp is a special lamp that emits ultraviolet (UV) radiation , intended to tan the skin by stimulating melanin production. These lamps are used in tanning beds, facial tanners, and medical applications such as the treatment of skin diseases.
How does a tanning lamp work?
A tanning lamp emits UV radiation , which is divided into three types:
- UV-A (320-400 nm) – Penetrates deep into the skin and stimulates existing melanin, causing the skin to tan quickly.
- UV-B (280-320 nm) – Stimulates the production of new melanin and promotes the thickening of the epidermis. This contributes to a longer-lasting tan, but can also cause sunburn.
- UV-C (100-280 nm) – Normally filtered , as it is harmful to skin and eyes.
Most tanning lamps use a combination of UV-A and UV-B to achieve a balanced tanning result.
Types of tanning lamps
🌞 Low-pressure fluorescent lamps – Used in tanning beds and home tanning equipment. They contain mercury vapor and a phosphor coating that emits UV light.
🔆 High Pressure Metal Halide Lamps – More powerful tanning lamps often used in professional tanning beds.
💡 Facial Tanners – Compact tanning lamps for targeted use on the face and décolleté.
Benefits of a tanning lamp
✅ Fast tanning without being dependent on sunlight
✅ Stimulates the production of vitamin D (important for bone health)
✅ Can help with skin problems such as psoriasis and eczema (under medical supervision)
Risks and disadvantages
⚠ Increased risk of skin cancer – Excessive exposure to UV radiation can lead to DNA damage and skin cancer.
⚠ Accelerated skin aging – UV rays break down collagen, which can cause wrinkles and pigment spots.
⚠ Sunburn and eye damage – Without proper protection, UV rays can burn skin and cause eye damage (always wear UV glasses!).
Safe use of tanning lamps
✔ Wear UV protective glasses to prevent eye damage.
✔ Build up exposure gradually to avoid burns.
✔ Stick to the recommended session duration and frequency (usually max. 2-3 times per week).
✔ Hydrate the skin well after using a tanning lamp.
Although tanning lamps are effective, dermatologists often prefer self-tanners or controlled exposure to natural sunlight , as these are safer for the skin.
