All the epigenetic masks which come with the Vibrational beauty products are extremely active and deeply cleansing. Therefore, in the case of some heavily intoxicated or reactive skin types, they may produce a reddening effect due to a significant increase of vascularization. The flush will naturally disappear in 20-30 minutes, giving a sense of freshness and firmness to the skin, lasting for the next few days. For the first and second use, it is recommended to apply the mask for 10 minutes and then gradually extend the time up to 20 minutes. Once the mask is removed, you can apply any cream or fluid or leave your skin as it is. The sense of tightness is caused by the increase in vascularization and by an electrolytic process on the sodium-potassium pump (increase of extracellular water).
