Extra helpful skincare tips:
Facial steaming 1-2x per week (i like to steam with matcha powder and himalayan salt after i cleanse)
Putting an oil on AFTER creams. oils don’t hydrate, they seal.
Learning to sleep on your back. i like to put 2 claw clips on each side of my face to avoid me rolling over to the side!
Taking a collagen powder in my morning smoothie.
Double cleansing with my cleanser. i don’t buy an oil cleanser
Facial yoga and massages.
