MYTH: Rubbing your wrists together will destroy the molecules in your perfume.

This just isn’t true. Spritz perfume 10-12 inches away from your body, on pulse points where the blood vessels are closest to the skin, behind the earlobe, wrists, cleavage and behind the knees.  The perfume will them respond to your body heat and emit scent throughout the day.

FACT: You should change your deodorant every six months.

Switch deodorants every 6 months or so because you will build a resistance to it. The alcohol in deodorants keeps your skin at a low pH to fight off the bacteria. Just like bacteria becomes resistant to antibiotics, your underarms will become immune to the ingredients in your deodorant.

MYTH: If a skin care product doesn’t work after one week, you should stop using it because it is not going to help your skin.

Any changes from products you see immediately are temporary and superficial. To see best results you need to wait at least a full skin cycle which is 4-6 weeks, but ultimately 10-12 weeks before you notice a change. The first call of duty of skin products is to repair the damage in the lower layers of the skin, then provide a supporting network and finally you will notice improvements in the mirror.

FACT:  Women age just like their mothers.

A study by Loma Linda University Medical Center used computer modeling and 3D camera to examine 40 mother-daughter pairs. The study found the way we age is genetic. The depth of wrinkling and sun spots is in our control because that is dependent on sun exposure, but otherwise, ladies age exactly like their mothers.
