Hi, thank you for your question. We do not recommend using this picosecond laser pen on cherry angiomas, as they are small blood-vessel clusters rather than pigmentation or tattoo pigment. This device is intended for dark spots, freckles, pigmentation, and tattoo fading. For cherry angiomas, please consult a dermatologist, as they usually require professional treatment such as vascular laser, electrosurgery, or cryotherapy.
