At present, the treatment methods for facial pigmentation include general treatment, drug treatment, physical treatment, etc. Since there are many types of pigmentation, complex formation causes, and large individual differences, there is no best way to treat it, and patients need to choose the appropriate treatment plan according to their specific conditions and medical advice.
1. General treatment: patients should identify the causes of pigmentation (long-term ultraviolet radiation, endocrine imbalance, improper use of cosmetics or skin care products, etc.), avoid triggers, maintain good living habits, and patients with chronic underlying diseases causing pigmentation should actively treat the primary diseases (e.g. endocrine system diseases, etc.). （Patients with chronic underlying diseases causing pigmentation need to actively treat the primary diseases (e.g. endocrine system diseases, etc.).
2. Drug therapy: drugs commonly used in the treatment of pigmentation include hydroquinone drugs (such as hydroquinone cream), non-hydroquinone drugs (such as niacinamide, azelaic acid, aminocyclic acid, etc.); both can inhibit the activity of tyrosinase, affecting the production of melanin, which in turn can reduce the effect of pigmentation.
3. Physical therapy: patients can also choose photorejuvenation, picosecond laser and other physical methods to reduce facial pigmentation and achieve the effect of reducing pigmentation.
Specific treatment plan needs to be combined with specific conditions and patients’ needs to choose, and cannot be generalized. For example, freckles are mostly related to heredity and sun exposure, so physical therapy is often used; chloasma is excessively related to endocrine disorders, so patients can use medication or combined laser therapy.
Therefore, it is suggested that patients should go to regular hospitals for consultation, and under the guidance of professional doctors, formulate relevant treatment plans for their specific conditions, and follow the doctor’s instructions to receive treatment.
