Because Protection Cream is also an anti-aging, moisturizing cream, you do not need to apply a separate Essence or Serum underneath, especially in summer. If you have extremely dry skin, you can pair it with our All-in-One Essence, Vitamin C Serum, or Skin Firming Concentrate.  If you have combination or oily skin, you can use it alone. If your skin is dehydrated but not dry and you want a silky finish, you can pair it with All-in-One Essence Oil-Free.
