PicoSure^® picosecond laser

PicoSure picosecond laser at 755nm, combined with a focus lens array, enables epidermal melanocytes to produce laser-induced optical breakdown (clinically LIOB) by focusing energy on the focus lens array. Melanin vacuolation only occurs in the epidermis and does not cause direct damage. It stimulates deep melanocytes, lowers the darkening rate and shortens the recovery period. Picosecond shock waves transmit to the deep collagen region, causing collagen damage, initiating a repair signal, promoting growth factors and elastic fiber regeneration.

Indications

• Melanin
• Wrinkles and textures
• Tattoos
• Concave scars

Contraindications

• Women who are pregnant or planning to become pregnant, who are breastfeeding, and who are sensitive to light.
• Sunburned, acne-inflamed skin.

Postoperative health education

• After treatment, the skin receives a lot of heat energy for a short time and will feel dry. Please strengthen moisturizing and apply an ice compress for 15 to 20 minutes.
• It is normal for a few people to have reddish skin, slight burning, itching and local papules after treatment. The symptoms will gradually subside within a few minutes to 24 hours. If you still feel unwell, you can apply an ice compress or make a return visit for examination.

Postoperative precautions

• Avoid irritating skin: Use neutral warm skin cleanser to clean face within one week after treatment. Avoid having a sauna, SPA, steam bath, exfoliation and a facial. Do not use irritant products, whitening or acidic products, such as AHA, retinoic acid, salicylic acid, kojic acid, high levels of vitamin C, alcohol, and granular products (for example, SKII skin care products should be temporarily suspended for one week).
• Moisturizing: After laser treatment, strengthening moisturizing can make the skin play the greatest role in repairing. It is advised to use mild and neutral moisturizing products without fragrances and preservatives.
• Sun protection: It can reduce the damage of ultraviolet rays and avoid the loss of collagen. It is suggested that sunscreen with SPF 30 or above be used and reapplied every 2-3 hours, with a parasol and a sun hat also recommended.
• Single deep spot therapy or tattoo therapy: Gray, black and white thin scabs will appear on the treatment site. Please apply ointment or artificial skin according to doctor's advice to reduce discomfort and promote wound repair.
• Pigmented spots and tattoo removal: After treatment, the site is slightly swollen and reddish. An ice compress can be applied for 15-30 minutes. The scab on the face will fall off naturally after 5-7 days, while that on the limbs will fall off naturally after 1-2 weeks. Do not remove the scab when wiping it gently. If blisters occur after tattoo removal, do not squeeze the fluid out of the blister by yourself. It is advised to return to the doctor for examination.

Treatment interval

• Usually more than 3 treatments are needed (depending on the individual's condition). Another treatment is performed 4-6 weeks later.
• Multiple treatments are required for the tattoo depending on its size, color, position and pigment, and the treatment time is about 6~8 weeks, which can be adjusted according to the doctor's advice.
