Based on the provided reference, smokers do not have thinner skin; in fact, smokers tend to have thicker epidermis and dermis layers. The study suggests that smoking leads to a higher thickness of these skin layers, along with lower echodensity and reduced elasticity.
Here's a breakdown:
-
Skin Thickness: The study indicates that smoking is associated with increased thickness of both the epidermis and dermis, the two primary layers of the skin.
-
Echodensity: The reference also mentions lower echodensity in the skin of smokers. Echodensity relates to how skin reflects ultrasound waves; lower echodensity suggests changes in the skin's structure.
-
Skin Elasticity: Smokers experienced reduced skin elasticity compared to non-smokers. This implies that the skin's ability to stretch and return to its original shape is diminished.
-
Nasolabial Folds: The study noted that nasolabial folds (lines from the nose to the mouth) were more prominent in smokers.
It's important to note that while the thickness of the skin may be increased, other characteristics like elasticity and echodensity are negatively affected.
