1. Ingredient issue: If water-based dairy products contain irritating ingredients, excessive oil, or ingredients that are not suitable for individual skin types, such as certain spices, preservatives, or acne causing ingredients, long-term use may cause pore blockage, leading to acne.
2. Improper cleaning: If the skin is not thoroughly cleaned after using water lotion, residual skincare products may clog pores, provide an environment for bacterial growth, and increase the risk of acne.
3. Skin mismatch: Everyone's skin type is different, and their reactions to skincare products are also different. If water-based dairy products are not suitable for one's skin type (such as using overly moisturizing products for oily skin), it may lead to an imbalance in skin oil secretion, resulting in acne.
