How to remove patchy dark spots on both cheeks

Generally, the appearance of patchy pigmentation on both cheeks may be caused by factors such as genetics, sun exposure, aging, endocrine disorders, or seborrheic dermatitis. Treatments such as photorejuvenation, laser pigmentation removal, PicoSure, or medication can be used under medical supervision to remove these spots. A detailed analysis is as follows:

1. Genetics

Genetic factors determine individual sensitivity to pigment metabolism. Some people are naturally prone to developing patchy pigmentation on both sides of the cheeks. It is important to avoid prolonged sun exposure and to use sunscreen regularly. Photorejuvenation treatment may also be performed under a doctor's guidance. This procedure uses intense pulsed light to break up melanin particles and promote skin metabolism, thereby lightening pigmentation. The typical reference cost for photorejuvenation is 2,000–5,000 RMB per session. Improvement is usually visible within 3–7 days after treatment, although side effects such as post-inflammatory hyperpigmentation may occur.

2. Sun Exposure

Prolonged exposure to strong sunlight causes ultraviolet radiation to stimulate melanocytes, leading to increased pigmentation and the formation of large patches on both sides of the face. Wearing hats and sunglasses and applying high-SPF sunscreen when outdoors can help prevent this. Laser pigmentation removal, performed under medical guidance, uses targeted laser energy to break down melanin particles and accelerate pigment metabolism, thus fading dark spots. The typical reference cost for laser pigmentation removal is 3,000–8,000 RMB per session. Results are generally noticeable within 5–10 days after treatment, though temporary side effects like skin darkening (rebound pigmentation) may occur.

3. Aging

As people age, skin metabolism slows down, reducing the efficiency of pigment clearance. This can lead to pigment deposition on the cheeks, forming irregularly shaped patches. Maintaining skin hydration with moisturizing products is essential. Under a doctor’s recommendation, PicoSure treatment—utilizing ultra-short pulse laser energy—can rapidly shatter melanin particles and enhance pigment elimination to fade spots. The typical reference cost for PicoSure treatment is 5,000–10,000 RMB per session. Improvements are usually seen within 7–10 days post-treatment, although potential side effects include skin burns or irritation.

4. Endocrine Disorders

Stress, chronic sleep deprivation, and similar factors can disrupt endocrine function, causing hormonal imbalances that overactivate melanocytes, resulting in patchy pigmentation on both sides of the face. This condition may be accompanied by symptoms such as menstrual irregularities and mood swings. Treatment may include medications such as Xiaoyao Pills, Chaihu Shugan Pills, or Danggui Tiaojing Granules, taken as prescribed by a physician.

5. Seborrheic Dermatitis

Seborrheic dermatitis is typically caused by excessive sebum production and inadequate skin cleansing, leading to clogged hair follicles and inflammatory reactions. Inflammation can trigger post-inflammatory hyperpigmentation, resulting in patchy discoloration on the cheeks. Symptoms may also include itching and flaking. Treatment should follow medical advice and may involve topical or oral medications such as tacrolimus ointment, vitamin B2 tablets, or compound ketoconazole cream.

If necessary, it is recommended to visit a reputable medical facility and undergo treatments under the guidance of a qualified professional to ensure safety and effectiveness. To prevent and improve facial pigmentation, individuals should avoid prolonged sun exposure, maintain clean and well-hydrated skin, eat a balanced diet rich in vitamins and antioxidants, and maintain regular sleep patterns and emotional well-being.
