Some of the best advice I received years ago when I started in the skincare beauty industry was "Be Consistent". It really is simple advice. No matter what you are using or doing consistency is the key.
It is just like working out or even a diet. If you only workout once a week you do not get a lot of benefit from it. I am guilty of skipping a few days at time too.
Your skincare regimen can be simple. It does not have to be complicated.
Just be consistent!
