SKIN. Part 2. ⠀ So, to keep the top (3rd) layer of skin healthy and young for as long as possible, we need to follow 2 rules. ⠀ The 1st rule is associated with the 5th floor: it is crucial to retire grannies on time or we may develop skin with uneven texture and unhealthy colour + it will make it harder for our skin care products to penetrate. ⠀ 2nd rule is associated with the 1st floor. ⠀ JOURNEY. Inhabitants of the Epidermis move from the 1st to the 5th floor in approximately 28 days. The older we get, the slower they move. The whole journey may become 2-3 times longer. It means that instead of having 28 days old grannies on the 5th floor, we have 42 or even 72 days old nans! As a result, our skin does not look as fresh and young anymore.. ⠀ NEWBORNS. Inhabitants of the 1st also become less active and produces less inhabitants, making skin thinner and more fragile. ⠀ So, the 2nd rule in order to keep skin young and fresh is to regularly activate/stimulate/wake up the cells of the 1st floor, so they constantly produce decent amounts of new cells which will keep our skin fresh and strong.
