Picosecond laser is the most popular laser technology in the medical beauty industry in recent years. In the past, we have received many inquiries from customers.
The following is several common questions about KM picosecond laser, hoping to help you further understand your skin problem needs.
Q1: What can HM picosecond laser do?
A: KM picosecond laser can achieve multiple effects such as brightening skin tone, reducing fine lines, improving sagging, improving enlarged pores, removing acne marks and repairing acne scars while treating pigmentation problems. In addition, multiple wavelengths and handpieces are used to effectively treat stubborn pigmentation such as melasma and brown-blue nevus.
Q2: How often does HM picosecond laser need to be used?
A: We recommend that customers maintain a 4-6 week interval during treatment to allow the broken melanin to be excreted from the body through metabolism, so that the skin has enough time to repair itself. Generally, shallow pigmentation such as freckles and sun spots will have a very significant lightening effect after 1-3 treatments; some more stubborn deep pigmentation such as brown spots require more than 3 treatments; but mixed pigmentation such as melasma is treated with a mild wavelength in combination with other treatment plans of dermatologists (such as topical medications, daily living habits). The number of treatments varies from person to person, and generally melasma will fade after 2-3 times.
Q3: Are there any risks of HM picosecond laser? A: After treatment, the skin will experience redness, swelling and itching, which will generally disappear within 24-48 hours. Some pigmentation will deepen after treatment, and even small red spots or scabs will appear, which will generally disappear within a week. Normal treatment will not cause blisters and burns. If there are any abnormalities, please contact the relevant personnel immediately.
Q4: What are the precautions before and after the HM picosecond laser treatment?
Before treatment 1. Avoid sun exposure 4 weeks before treatment. Do not undergo laser treatment if you have sunburn/redness 2. Stop using oral and topical products containing vitamin A acid, fruit acid, and bleaching ingredients for at least 48 hours 3. People with lip sores cannot undergo laser treatment; the therapist will avoid using laser near the wound 4. If you are undergoing IVF treatment, pregnant or breastfeeding, you must inform the medical beauty center to decide on the treatment plan 5. Please arrange this treatment at least two weeks before important events, such as weddings, parties, etc.
After treatment 1. Reduce outdoor activities within one week and avoid direct exposure to the sun within four weeks. Whether it is sunny or cloudy, you must apply SPF 30 or above and sunscreen with UVA and UVB protection indoors or outdoors 2. Avoid washing your face with hot water, steaming in the sauna, doing hot yoga and other activities within 24 hours after treatment to avoid skin sensitivity 3. Avoid makeup within 24 hours after treatment. If necessary, keep it light and pay close attention to skin changes 4. Please use appropriate skin care products according to the therapist's advice. If you use a mask, be careful to choose a non-irritating product.
Q5: How long does the effect of HM picosecond laser last? A: For general spots such as freckles or sun spots, after 1-3 treatments, a very significant removal effect will be achieved, and then the skin can be maintained for 2-3 months for daily maintenance and repair; but the recurrence of mixed spots such as deep and shallow spots such as melasma is relatively high, and its cause is also closely related to personal constitution, so the therapist and doctor will also use topical or oral medication to treat melasma. In addition, daily sun protection maintenance is very, very, very important. Please make sure that your sunscreen must be SPF 30+ and have UVA and UVB protection, and reapply every 2-3 hours.
Q6: Who is not suitable for HM picosecond laser? 1. Scar constitution There is a chance that small wounds will be produced during the laser process, and people with scar constitution are prone to scar hyperplasia. Local treatment can be carried out under the guidance of a specialist, and generally a small area treatment needs to be tested first. 2. Patients with autoimmune diseases Patients with lupus erythematosus or similar diseases that are allergic or reactive to sunlight are not suitable for full-face treatment. Local treatment can be performed under the guidance of a specialist, and generally a small area test is required first. 3. Vitiligo patients The body's immune system causes damage to melanocytes, and laser treatment will aggravate the condition and the possibility of spread.
