Can donkey-hide gelatin (Ajiao) improve skin appearance and remove spots?

Generally speaking, donkey-hide gelatin (Ejiao) may assist in enhancing beauty and improving complexion under specific conditions, but its effectiveness in removing pigmentation spots is limited. The detailed analysis is as follows:

Donkey-hide gelatin is rich in collagen and various amino acids. When sallow complexion and dry skin result from deficiency of qi and blood, moderate consumption can help replenish nutrients, improve dull skin tone, and promote a healthy, radiant appearance, thus playing a supportive role in skincare and beautification. However, the formation of pigmentation spots is associated with multiple factors such as genetics, sun exposure, and endocrine disorders. Ejiao does not have direct effects on lightening melanin or regulating the endocrine system, so it cannot effectively target or resolve pigmentation issues, resulting in limited efficacy for spot removal.

Consumption of Ejiao should be based on individual health conditions. People with weak spleen and stomach functions or those prone to heatiness should use it cautiously and preferably combine it with mild, cooling ingredients to balance its properties. For daily improvement of skin quality and reduction of pigmentation, proper sun protection is essential to prevent ultraviolet rays from worsening hyperpigmentation. Maintaining regular sleep patterns and consuming more vitamin-rich fruits and vegetables can also promote metabolism. Ejiao should be stored sealed in a cool, dry place to avoid moisture and spoilage, and once opened, it should be consumed promptly to preserve nutritional value and ensure safety.
