How many times does opt have the effect of removing spots

Opt freckle removal generally requires 3-5 treatments to show significant results, and the specific number of effective treatments depends on factors such as the type of pigmentation, skin metabolic capacity, and treatment parameter settings. Opt photon rejuvenation decomposes melanin through selective photothermal action, requiring multiple treatments at intervals between treatment courses to achieve the desired effect. The spot removal effect of opt is greatly affected by the depth of pigmentation. Superficial freckles or sunspots may improve after 2-3 treatments, and these pigments are mostly distributed in the epidermal layer, making it easier for light energy to target them. After each treatment, there will be a slight scab on the skin, and the skin tone will brighten when it falls off after 7-10 days. However, dermal pigmentation such as melasma requires a longer period of time, as melanin deposition is deeper and requires gradual metabolism through multiple accumulations of energy. Typically, 4-6 treatments are needed to stabilize the effect. The recommended treatment interval is 28-30 days, synchronized with the skin metabolic cycle. Some stubborn pigmentation may require additional intensive treatment. Congenital Ota nevus or deep inflammation with darkened color, due to high activity of pigment cells, requires an increase of 6-8 treatments. This type of situation needs to be accompanied by a low-energy multiple mode to avoid excessive stimulation causing anti blackening. Strict sun protection after surgery can help shorten the effective period, while insufficient UV protection may lead to pigment re accumulation. During treatment, it is recommended to use skincare products containing tranexamic acid and arbutin to assist in inhibiting tyrosinase activity. After completing the opt freckle removal treatment, it is necessary to continue to take good care of sun protection, use broad-spectrum sunscreen with SPF30 or above, and avoid prolonged outdoor exposure. Avoid high temperature environments within 24 hours after treatment and refrain from using irritating skincare products for a week. Daily supplementation of antioxidants such as vitamin C and vitamin E can reduce the stimulation of melanocytes by free radicals. Maintaining a regular daily routine during treatment and ensuring that the skin completes self repair during the golden time of night can help improve the ultimate effect of opt freckle removal.
