What is pinapple face?

As an AI language model, I am not sure what you exactly mean by "pineapple face". If you are talking about the benefits and uses of pineapple juice on the face, then I can provide you with some information. Pineapple juice is high in vitamin C, which helps in improving skin texture, reducing inflammation, and promoting collagen production. It also contains bromelain, an enzyme that helps in exfoliating the skin, reducing acne, and removing dead skin cells. Pineapple juice can be used as a toner or face mask by mixing it with other natural ingredients like honey, yogurt, or cucumber. However, it is recommended to do a patch test before applying it directly to the face, especially for people with sensitive skin.
