As the skin sheds naturally in a week or so, the tan begins to wear off. This makes the tan created by Erythrulose temporary and completely safe. If properly applied and the skin is kept nourished, the tan can remain for at least 10 days. The tan does not wash away or even sweat off once the complete tone has been developed.
The fading begins gradually as the skin’s normal exfoliation process takes place. The only way the tan will lighten sooner is by intense exfoliation or scrubbing of the skin, prolonged baths or swimming, as well as heavy sweating after a vigorous exercise.
Erythrulose is very expensive because it is difficult to obtain. Erythrulose has no side effects and due to its similarity in composition with vegetable DHA, it is unlikely for anyone to be sensitive to these two sugars. It reacts only with the skin cells of the upper layer and it does not penetrate below this layer.
