Is laser hair removal safe?

Laser hair removal effectively removes unwanted hair. In a process called photothermolysis, the laser light absorbed by the melanin in the hair thermally destroys the hair follicle and its bulb. The best results are achieved when the hair is in the active growth phase (anagen).

To permanently get rid of hair, a series of treatments is necessary. Key to the safety and effectiveness of hair removal is taking into account factors such as:

• choosing the appropriate type of laser, tailored to the skin tone and hair color (e.g., diode lasers, alexandrite lasers, Nd:YAG),
• precisely setting the laser power and wavelength,
• selecting an experienced and qualified specialist,
• conducting a detailed consultation before each treatment, including a medical history and a laser test,
• using only professional, certified equipment.

After laser hair removal, temporary skin reactions may occur. The skin may become red and slightly swollen. You may feel burning or irritation. These symptoms usually disappear quickly, often within a few hours, although they may persist for a few days.

Serious complications are much rarer and usually result from errors during the procedure or the patient not following recommendations. They may include burns, permanent discoloration, and even scars or skin infections. During the treatment, it is necessary to avoid moles and birthmarks to prevent damage to them.

Laser hair removal is safe and does not cause cancer. Laser light, unlike UV radiation, is non-ionizing, which means its energy does not damage the DNA of cells or cause cancerous mutations. Melanin in the skin simply absorbs this energy. Numerous scientific studies consistently confirm the lack of a link between this procedure and the development of skin cancers. However, it should be noted that active cancer or a history of cancer are absolute contraindications to laser hair removal. Prior medical consultation is always required.

Depilation laser is a safe method of hair removal, however, before the procedure it is necessary to familiarize yourself with a list of contraindications. The procedure should be postponed in case of:

• pregnancy and breastfeeding,
• fresh sunburn (from sun exposure, tanning beds, self-tanners),
• active skin conditions such as psoriasis, vitiligo, rosacea,
• infections in the area being treated,
• use of photosensitizing medications and herbs, including retinoids, certain antibiotics, and St. John's Wort,
• use of exfoliating cosmetics (containing acids like AHA, BHA, azelaic acid) and chemical peels,
• epilepsy, - tendency to form keloids,
• certain hormonal disorders (e.g. PCOS) that may reduce the effectiveness of the treatment.

It is worth noting that laser hair removal is not effective for blonde, gray, or red hair that does not contain sufficient melanin.

The safety of laser hair removal is a shared responsibility of the patient and the specialist. Always choose a clinic with experienced staff and equipment certified for safety – this is the basis of security. Before the procedure, consult with a specialist to assess your skin and exclude any contraindications for hair removal. It is also essential to prepare your skin for the procedure: avoid sunbathing (sun, tanning beds) and self-tanners for several weeks before the treatment to minimize the risk of complications.

After the treatment, key is skin care focusing on moisturizing and regeneration. Use gentle products, such as creams with D-panthenol or aloe vera gel. Avoid hot baths, saunas, and intense physical activity for at least a day after the procedure. Consistent use of high sun protection is extremely important. Protect the treated areas from UV radiation by using SPF 50 sunscreen. This will prevent discoloration.

Home depilatories use Intense Pulsed Light (IPL) technology, which is safe to use. They emit weaker and less precise light than professional lasers. Modern IPL devices are equipped with a number of safety features, such as:

• skin color sensors that automatically adjust the power,
• skin contact sensors that protect against uncontrolled flashes.

IPL depilatories effectively reduce hair growth, although they do not permanently eliminate it. It is important to always follow the rules of use for safety. Before using such devices, it is necessary to perform a test on a small patch of skin. Remember that IPL technology does not work on very light hair or dark skin.

Feelings during laser hair removal are very individual. Most people describe them as gentle pricks, stinging, or a "rubber band snapping" sensation. The intensity of these feelings depends on the individual pain threshold, sensitivity of the treated area, and hair density and thickness. Modern laser devices are equipped with advanced cooling systems. They effectively lower the skin temperature just before emitting the pulse, which minimizes discomfort and significantly increases the treatment's comfort. Individuals with a very low pain threshold or those undergoing hair removal on particularly sensitive body parts always have the option to use special numbing creams.
