Skin is a highly adaptable organ. At varying rates, it adjusts to all sorts of external conditions. It can cool you down (sweating), it can darken to block the sun (tanning), it can rebuild itself when injured (scabbing). When it comes to sudden exposure to dry conditions, the skin will reinforce its barrier to prevent moisture in the skin from evaporating. Thing is, it takes 3-4 weeks for cells to work from the bottom (hypodermis) up to the surface, for final shedding (desquamation). Which is why people going from temperate to dry conditions struggle more than those habituated to dry weather (we’re talking to you, people who go on ski trips or, for that matter, have cold winters). What to do? How about a little help supporting the barrier and keeping your skin hydrated?
