Ahh, young skin.

Who doesn’t want fresh, hydrated skin, the hallmark of beauty no matter a person’s age?

As you know, your skin takes a daily beating, fighting off both pollutants and sun rays.

But at night, your skin is repairing the damage it sustained during the day.

So, too, is skin blood flow.

One scientificstudyfound that your skin is more permeable in the evening.

Pregnancy, a time of fluctuating hormones, also triggers different circadian effects in your skin.

Possibly the most interesting scientific finding is that the skin’s beneficial circadian cyclesmay dwindle as we get older.

Overnight, though, their skin performed repairs and showed enriched metabolites in the morning.

For example,two different studiescame to opposite conclusions about skin reddening.

This experiment showed a higher level of skin reddening during the evening than in the morning.

Either way, both studies suggest that epidermis does not burn uniformly throughout a 24-hour day.

Instead, circadian rhythms influence your skin’s ability to tan, glow and darken.

So, how do you make all this data work for you?

Why not begin by appreciating your hard-working skin.

Be conscious and choosy with products.

Experiment not only withwhatyou apply for skincare butwhen.

Finally, remember that hydration is mainly an inside job, so enjoy another glass of H2O.
