Freckles (hereditary) Symptoms: Spots appear in childhood; irregularly distributed across the face; peak during adolescence; become more pronounced in intense sunlight during summer and fall.They intensify before menstruation and gradually worsen with age. They become more noticeable during digestive issues, emotional stress, or adverse weather conditions.
Deep Pigmentation (caused by chemical peels, cosmetic allergies, prolonged use of depigmentation creams, excessive UV exposure, etc.) Symptoms: Irregularly distributed spots, particularly prominent on the face, around the eyes, and on the cheekbones. Often appear as irregular patches or plaques on the face.
Café-au-lait spots (hereditary skin condition unrelated to sun exposure; may indicate multisystem disorders like neurofibromatosis): Symptoms: Permanent pigmented patches of varying sizes with well-defined borders.
Age spots (caused by reduced cellular metabolism, increased fat oxidation, and diminished activity of the antioxidant enzyme superoxide dismutase) Symptoms: Persistent pigmented patches of varying sizes, often appearing in clusters.The primary causes of facial spots are as follows:
1. Imbalance of Yin and Yang within the body: a. Liver qi stagnation leading to blood stasis in the face; b. Spleen-stomach deficiency preventing qi and blood from nourishing the face, causing damp-heat to ascend and form spots; c. Kidney yang deficiency resulting in scattered yang qi and blood stasis in the face, forming melasma.
2. Increased secretion of androgens and progesterone by the placenta during pregnancy. This commonly causes symmetrical melasma on the cheeks of pregnant women. However, after childbirth, when androgen and progesterone levels return to normal, most spots naturally fade or disappear.
3. Medication factors: 9%–20% of women taking oral contraceptives long-term are prone to melasma, with some developing facial spots as early as one month after starting. Additionally, medications for hypertension or diabetes, along with foods high in photosensitizing compounds (e.g., celery, coriander, carrots), may trigger melasma.
4. Other factors: Chronic conditions like hepatitis or tuberculosis can increase tyrosinase activity, boosting melanin production while reducing the body's ability to eliminate it. Accumulated melanin may eventually manifest as melasma on the face. Improper cosmetic use can also accelerate or worsen melasma development, contributing to various pigmentation issues.
Expert Tips: To effectively address pigmentation, first determine whether it is congenital or acquired. Congenital melanin often deposits deep within the skin layers, making it difficult to remove through skin exfoliation alone. Acquired pigmentation, however, can generally be managed more effectively by selecting appropriate skincare products.As we age, metabolism slows and self-renewal weakens, making spots increasingly stubborn to fade. Thus, establishing proper care in youth is paramount. Essential habits for effective spot reduction:
1. Strict sun protection.
2. Avoid heavy makeup.
3. Consume antioxidant-rich foods: Vitamin C (400mg/day), Vitamin E (200mg/day), green tea, OPCs, and collagen supplements.
4. Practice gentle massage and consistent hydration.
5. Use whitening products moderately.
6. Protect against radiation exposure.
7. Make exercise a habit.
8. Increase intake of: tomatoes, lemons, fresh jujubes, sesame seeds, walnuts, Job's tears, peanuts (rich in vitamins C and E, which promote blood circulation, inhibit the conversion of metabolic waste into pigmented substances, thereby reducing melanin production, accelerating skin metabolism, and promoting new cell generation).
Increase intake of:Lean meat, eggs, fresh milk, yogurt, potatoes, seafood (rich in protein to accelerate skin recovery and restore physiological functions)
9. Limit: Dark-colored condiments like soy sauce, vinegar, and curry; spicy foods and beverages such as chili peppers, mustard, and alcohol.
