Red Stretch Marks When stretch marks are still purplish and red, it is the best time to treat them. Pulsed dye laser is recommended, and fractional laser and radiofrequency are also available for treatment. Pulsed dye laser is generally used to treat the dilated blood vessels of early swelling marks, and can effectively improve red stretch marks by promoting the fading of over-constructed blood vessels. Topical retinoic acid is suitable for people who cannot receive laser treatment for red stretch marks.

And its teratogenic risk, pregnancy and breastfeeding mothers are also not applicable. 2, white stretch marks Fractional microneedle radio frequency, also known as gold microneedle radio frequency, is a combination of fractional, microneedle, radio frequency in one technology, through the microneedle mechanical penetration of the epidermis, the radio frequency energy in fractional mode directly into the deep target tissue, stimulate collagen contraction, while initiating secondary trauma healing response, and promote dermal reconstruction. Fractional Laser Fractional laser involves the delivery of narrow laser columns to the skin to create vertical bands of thermal damage and induce a damage healing process to improve pigmentation abnormalities and skin texture. Both exfoliative and non-exfoliative fractional lasers are used to treat white lines and are more effective. With non-ablative fractional lasers, the risk of complications is lower and the appearance of the swollen lines is visually improved after treatment.
