Why summer skin needs light hydration

Surface oil is not the same as hydration. Dehydrated skin can become oilier while still lacking water, so a water-light serum is often more comfortable than a rich cream.

Myth: Oily summer skin doesn't need hydration.

Fact: Even oily-feeling skin can be dehydrated and benefit from a lightweight serum.

What to look for in a summer serum

  • Oil-free texture.
  • Hyaluronic acid.
  • Centella asiatica.
