Whitening essence has stronger efficacy than other essences and is generally classified as functional skin care products. If used every day, it may cause excessive irritation to the skin, resulting in the loss of the original balance of the skin and some adverse reactions, such as dry skin, redness and itching.

In addition, excessive use of whitening essence may make the skin dependent on this ingredient. Once you stop using it, your skin may rebound.

Therefore, it is recommended not to use whitening essence every day, to choose the appropriate frequency according to your skin condition and needs, or to consult a professional dermatologist for better skin care advice.
