You must have wondered many times – how does the cream know if it is day or night?

Chronobiology is not just a marketing ploy by which the beauty industry will reach into your wallet and make you spend twice as much as planned, as many skin processes and functions do change depending on the time of day.

So here are a few dashes that will make it easier for you to properly apply your skin care products.

MORNING

• sebum production is at the highest level to protect the skin from external factors (the importance of using appropriate products for acne problems)

• the skin is the least sensitive to allergens around 11 o’clock (application of care products for intolerant, hyperreactive skin)

DURING THE DAY

• Transepidermal water loss (TEWL) is at the lowest level to prevent dehydration and provide protection from external factors (wind, sun, cold, pollutants -) – the right time for hydrating and anti pollution care

• reduced cell division (minimum between 12 and 13 hours)

• minimal blood circulation in the skin for about 14 hours

IN THE EVENING

• the skin is most sensitive to allergens (resist the temptation and try a new product the next morning)

DURING THE NIGHT

• sebum production is at its lowest level (which is why night creams are usually richer in texture)

• skin regeneration takes place intensively in the period between 23 and 4 hours with the culmination of cell division for about 1 hour (thus avoiding the potentially harmful effects of UV rays that cause mutations and of course no need to use products containing SPF)

• maximum blood circulation in the skin between 23 and 4 hours helps eliminate toxins and supply the skin with the nutrients needed for its proper and complete regeneration (after proper and thorough cleansing and exfoliation, use nourishing creams)

•maximum skin permeability (highest TEWL) means reduced skin barrier function, but also the highest susceptibility to active ingredients from topical preparations (a good nightly  serum is gold worth).

In the end I can only add, give your skin what it needs at the right time!
