Contraindications and precautions for laser hair removal

Although there is no minimum age indication for this treatment, it is generally not recommended for those under 15 years of age. Due to its mechanism of action, it is also not recommended for elderly people with gray hair, who do not have melanin in their bodies and cannot absorb the energy released by laser or IPL devices.
At the same time, the following conditions are also not recommended:
•  Skin diseases and autoimmune diseases that are aggravated by light exposure, such as systemic lupus erythematosus(SLE)
•  Active infections or wounds in the affected area that require treatment, such as herpes or staphylococcal infections
•  Patients with keloids or tendencies of keloids
•  Patients are at risk of developing Koebner phenomenon due to psoriasis and vitiligo
•  Patients using photosensitizing medications
•  Patients using oral isotretinoin(generally recommended to stop 6 months to 1 year after medication)
•  Areas with hyperpigmented hesions or tattoos
Before the treatment:
Before the hair removal treatment with diode laser or IPL devices, you should avoid sun exposure, as the skin should not be tanned during the treatment. And you should stop using the tretinoin cream at least 2 days before the treatment. And you should not wax, use epilators or pluck hair for at least 1 month before the treatment. And you should shave with a razor the day before the treatment. Be aware of medication use in the weeks and days before the treatment, as many drugs such as antibiotics, antihypertensive drugs, anti-inflammatory drugs are photosensitizing and increase the risk of pigmentation after the treatment. Do not use bleaching products before the treatment. Avoid creams, talcum powder, deodorant, makeup, as the skin needs to be clean.
Before the treatment, the doctor need perform a physical examination to determine the device settings to use and ask about your medical history, medications use, etc. To evaluate any contraindications. And the doctor may also perform a small test on a small hidden area of your skin to test how your skin responds to the treatment and the effectiveness and safety of the selected device setting parameters.
Cooling technology can be used to avoid pain and severe discomfort, such as cooling gel.
After treatment
Sun exposure should be avoided for 6 weeks, especially on unprotected areas such as the face, and the use of sunscreen is recommended. Ice packs can be used to reduce redness and edema, as well as to relieve low-grade pain or discomfort, which is normal after treatment. It is best to avoid the use of creams, lotions, deodorants the day after treatment. If after treatment, the doctor notices signs of excessive inflammation in the treated area, he may prescribe a topical corticosteroid to reduce side effects.
How many treatments are needed to achieve satisfactory results?
There is no general consensus among professionals on the number of treatments required and the time interval between each treatment.
The number of treatments depends on the area to be treated, the patient’s characteristics and and the equipment used.
It is estimated that each treatment can permanently reduce the number of hair by 20-30%. in general, 3-8 treatments with an interval of 4-8 weeks are recommended.
