This may be because the skin is burned by excessive essential oil. In this case, mild base oil, such as calendula oil, can be applied to local skin, which is beneficial to relieve skin pressure and provide a source of protection, nutrition and ability for skin tissue recovery. In addition, drink as much water as possible to accelerate the circulation and excretion in the body, which also helps to discharge too much essential oil. Please don't use all kinds of cosmetics in the market during the recovery period, because it contains a lot of synthetic chemicals, which is not helpful to the recovery of the skin.
As for whether the skin can be restored to its original state, it is often related to the skin's regenerative ability. The younger the skin, the stronger the hair growth ability of the skin, and it will heal easily without even leaving any scars and pigments.
Finally, I would like to remind you that many so-called "beauty secrets" related to essential oils are unreliable, so be careful. For example, don't add unilateral essential oil to the mask. These essential oils are difficult to be fully diluted, and once the dose exceeds the tolerance of the skin, it is easy to cause local damage.
