It typically appears symmetrically on areas such as the cheekbones, forehead, and upper lip, and is particularly prevalent in women. Melasma is known to occur due to the overactivation of melanocytes, which produce melanin pigment, and is influenced by a combination of factors such as UV exposure, hormonal changes (pregnancy, oral contraceptive use), genetic predisposition, and stress.According to the Korean Dermatological Association, melasma can be classified into epidermal, dermal, and mixed types, and treatment response and prognosis may vary depending on the type. Therefore, accurate diagnosis and the establishment of a personalized treatment plan are crucial.What is Picotoning?Picotoning is a laser treatment method that selectively destroys melanin pigment by irradiating powerful laser energy for a very short duration, in picosecond (one trillionth of a second) units. It delivers energy in a much shorter time than conventional nanosecond (one billionth of a second) lasers, minimizing damage to surrounding tissues while breaking down pigment particles more finely, aiding in their effective removal.Picotoning can be utilized for treating various pigmentary disorders, including not only melasma but also freckles, blemishes, and tattoo removal. Thanks to its short pulse duration, thermal damage is reduced, which can help minimize the possibility of side effects such as post-inflammatory hyperpigmentation.How Does Picotoning Work for Melasma and What Effects Can Be Expected?Picotoning improves melasma through a photomechanical effect that finely breaks down melanin pigment. It delivers high energy instantaneously over a short period, shattering pigment particles with shockwaves, and these finely fragmented pigments are then absorbed and eliminated by the body's immune cells.Improvement of Pigmentation: It can help alleviate hyperpigmentation by effectively destroying melanin pigment, which is the primary cause of melasma.Skin Tone Improvement: It can contribute to making the overall skin tone more even and improving dullness.Induction of Collagen Regeneration: Some pico laser devices can provide micro-stimulation to the dermal layer along with pigment removal, inducing collagen production and thus positively impacting skin elasticity improvement.The effects of Picotoning may vary depending on an individual's skin condition, the depth and type of melasma, and the number of treatment sessions. Generally, gradual improvement can be expected through multiple repeated treatments.What are the Picotoning Treatment Process and Precautions?Treatment ProcessPicotoning treatment generally follows these steps:Skin Diagnosis and Consultation: A specialist accurately diagnoses the skin condition and melasma type, then establishes a suitable treatment plan for the individual.Cleansing and Anesthesia: The treatment area is thoroughly cleansed, and an anesthetic cream may be applied to reduce discomfort.Laser Treatment: The specialist adjusts the laser intensity and number of shots according to the individual's skin condition to perform the treatment.Soothing Care: After the procedure, a soothing pack or cream is applied to the skin to alleviate irritation.PrecautionsUV Protection: Thorough UV protection is essential before and after the procedure. UV exposure can worsen melasma and hinder treatment effectiveness.Moisturizing Care: The skin may become dry after the procedure, so adequate moisturizing care is important to strengthen the skin barrier.Avoid Excessive Stimulation: Avoid rubbing the treated area or using irritating cleansers.Consult a Specialist: If unexpected reactions such as redness, itching, or hyperpigmentation occur after the procedure, consult a specialist immediately.Importance of Repeated Treatments: Melasma is a chronic condition that is difficult to cure with a single treatment, so it is important to undergo consistent, repeated treatments as directed by a specialist.Melasma Treatment: Consultation with a Specialist is EssentialMelasma is a refractory pigmentary disorder caused by complex factors, and the most suitable treatment method may vary depending on an individual's skin condition and the type of melasma. In addition to Picotoning, various other methods exist, including medication, skincare, and other laser treatments.Therefore, if you are considering melasma treatment, it is crucial to have a thorough consultation with a dermatologist to receive an accurate diagnosis and establish a personalized treatment plan.
