Your skin gets redder than before.
However, yellow isn't the only new color your skin might adopt in your 40s. Dr. Nesheiwat cautions that aging skin also tends to get redder than it may have in your earlier life.
Why is my skin redder as I get older?
The stress hormones responsible for your fight-or-flight response boost body heat, which in turn can lead to flushed and even blotchy skin.
Why is my face getting redder with age?
Facial redness can be caused by a number of conditions, including rosacea, broken blood vessels from sun damage, seborrhea and acne. These conditions may be congenital or onset with age.
