LASER TREATMENT FOR LIP DEPIGMENTATION

The color of the oral mucosa varies based on factors such as location, function, and underlying tissues, although it is often pink. Lips play a major role in our smiles, and they are beautiful in both form and color. Individual differences in melanin synthesis, skin tone, vascularity, and lip dryness (dehydration) are common causes of lip color variation. Melanin is the primary component that determines the color of lips among them. Although lip hyperpigmentation is not a medical emergency, it is often seen as unsightly, may have an impact on a patient’s social interactions and self-esteem, and causes them to look for treatments. Etiology: Physiologic factors, such as hyper-melanin pigmentation, are the most frequent cause. Once any malignant alterations have been ruled out, the laser is used electively to remove lip pigmentation. Treatment modality: A variety of methods have been used to address lip depigmentation. Melanin pigmentation is often found in the epithelium layer and may sometimes extend to the basal layer; as a result, it is superficial and simple to access and remove. Techniques for lip melanin depigmentation include chemical peeling, cryotherapy, photodynamic treatment, pink tattoos, and topical medications such liquid nitrogen, vitamin C, arbutin, and hydroquinone. All of these treatments had varying results, side effects, and potentially unsatisfactory aesthetic consequences for the patients; yet, lasers produced excellent, acceptable results in terms of appearance and patient tolerance. To carry out this treatment, Pioon Laser provides a variety of wavelengths, including 450 nm, 810 nm, and 980 nm, which may be employed in a contact or non-contact way. In this instance, the patient had a clinical examination, all laser safety measures were observed, and an informed permission was obtained after a thorough description of the surgery. The patient’s lips were covered with anesthetic gel. The patient was instructed to open their mouth widely, and the depigmentation procedure was performed sequentially clockwise, starting at the top lip and working down to the lower lip. In contact mode, a wavelength of 980 nm was used, and in continuous mode, the laser setting was 1 watt. In2012, Sana Farista presented case studies of effective diode laser lip depigmentation procedures. Additionally, a case report detailing a procedure carried out using the specified laser settings without any unfavorable patient responses was published by Islam Kassam in 2016. justification for using lasers Lasers are great hemostatic agents because they are absorbed by the pigments in the soft tissue. Its benefits also include the ability to potentially decontaminate and sterilize, reduced time spent chairside, treatment completion in a single visit, and ease of handling tissues. In conclusion, lip hyperpigmentation should be taken into consideration as it might conceal an individual’s overall look. It has been shown that using a diode laser is a safe and efficient way to treat patients while achieving the best possible cosmetic results with the least amount of pain. Reference: Iyer vh, Farista s. Two case reports on the therapy of lip hyperpigmentation with a 940 nm diode laser. Initial case report and lip depigmentation (pinkification) using an 810nm diode laser according to Islam Kassim et al.’s procedure are published in Int J Laser Dent 2014;4(1):31–38.
