Patients with a full face of freckles can remove them through medication, laser treatment and general measures as prescribed by doctors. 1. Medication: Usually for patients with light color, they can be treated with 30%~35% trichloroacetic acid solution or phenol according to doctor’s instruction, while some patients can also use 3% hydroquinone cream, 0.05% retinoic acid cream, vitamin E milk and other medicines to alleviate the freckles, but they generally cannot be eliminated completely. 2. Laser treatment: patients can choose to be treated by frequency-doubled Nd:YAG laser, Q-switched ruby laser, Q-switched emerald green gemstone laser, IPL intense pulsed laser, etc. under the guidance of doctors, so as to make the pigment particles burst without damaging the nearby tissues. However, this treatment cannot prevent recurrence, and patients need to take active measures to prevent sunlight after treatment. 3. General measures: patients usually need to pay more attention to personal hygiene, keep the skin clean, and also need to actively regulate diet, appropriate consumption of vitamin E and vitamin C-rich fruits and vegetables. Patients usually need to develop good living habits, avoid staying up late at night and keep a happy mood, which is helpful for the recovery of the condition. It is suggested that patients with freckles should seek medical treatment in time and take targeted treatment under the guidance of doctors to avoid aggravation of symptoms.
