First of all, not all olive oil can be used for skin care. I'll tell you how to distinguish olive oil. Olive oil can be divided into manor grade extra virgin olive oil, extra virgin olive oil, extra virgin olive oil, refined olive oil and olive oil residue. Olive pomace is usually used in cosmetic olive oil. In order to add special effects, chemical components will be added and it cannot be eaten. Beauty olive oil can't be called oil, only olive extract, which is the worst quality.

Manor grade and extra virgin olive oil can be eaten or used on the face. This is olive oil with the highest purity and the least impurities. It is the best olive oil, and the extracted ingredients are also the most refined.

Other lower-level refinements are not very fine, so for facial skin, insensitive people are fine, and sensitive people are not suitable. Polyphenols and unsaturated fatty acids are easy to cause allergies.

Therefore, when choosing, it is best to choose the original imported extra virgin olive oil.

The longer olive oil is left, the more acidity it will gradually increase, which is not good for the skin. Many olive oils have been tested for acidity less than 0.3, but they were taken back and repackaged with 1. It took two years to sell them. If the acidity is greater than 0.5, it is marked as 0.3. The packaging date is new, so you'd better buy new imported olive oil, and don't rub it on your face if it expires.
