When a thermal mask cools, what happens to the skin?

When a thermal mask cools, the skin undergoes a tightening and toning effect. This happens because the cooling process causes the blood vessels to constrict, which can reduce swelling and inflammation. As the mask cools, it also contributes to the stimulation of collagen production, which is important for maintaining the skin's elasticity and firmness.

The tightening effect can provide a lifting sensation and make the skin appear more toned. This process is beneficial in various aesthetic treatments, as it can enhance the overall appearance of the skin. By promoting a firmer texture, the cooling of a thermal mask plays a vital role in skin rejuvenation and contributes to a more youthful look.

Other options suggest effects like dehydration or inflammation, which do not accurately represent the physiological responses of cooling on the skin. Instead, the correct understanding of how thermal masks work highlights their ability to assist in skin tightening and toning, making this the appropriate choice.
