How long the hand cream can last depends on the frequency of personal use and the skin condition of hands. If you only apply it once a day and use it moderately, the hand cream can last for about 1-2 months. If your hand skin is dry, you may need to use hand cream more frequently, so its service life may be shortened accordingly.

Regarding whether you can eat it immediately after applying hand cream, we need to pay attention to the ingredients of hand cream. Usually, the ingredients in hand cream are safe and harmless, and will not cause direct harm to human health. However, some hand creams may contain spices or other additives. If you are allergic to a certain ingredient or sensitive to a certain taste, eating it immediately after application may affect your appetite or cause discomfort. Therefore, it is best to wait for a period of time after applying hand cream, so that it can be fully absorbed and dried before eating.

If the hand cream you use contains special ingredients (such as whitening and exfoliating), it is recommended to wait for a longer time after use to avoid these ingredients affecting food. To be on the safe side, it is best to wait for a while after using hand cream.

It should be noted that everyone's skin condition and reaction to the ingredients of hand cream are different, so if you have any skin allergies or other uncomfortable symptoms, please stop using hand cream in time and consult a professional doctor or dermatologist for advice.

General hand cream can be used continuously for about 1-2 months, depending on the frequency of personal use and the skin condition of hands. You can eat it after applying hand cream, but it is best to wait for a while for it to fully absorb and dry before eating. I hope my answer is helpful to you!
