Best for

When this is a smart buy

  • Dry skin
  • Dehydrated skin
  • Compromised skin barrier
  • Anyone seeking intense hydration

Skip if

When this is the wrong lane

  • You have very oily skin and prefer lightweight, non-hydrating formulas
  • You are sensitive to humectants (though glycerin is generally well-tolerated)

Routine fit

Where this serum fits in

Apply this serum to clean, slightly damp skin. It works best as a hydrating layer before your moisturizer. For daytime use, always follow with SPF.

Why it works

Where it earns the slot and where it does not

The useful question is not whether this product is good in a vacuum. It is whether it makes your routine easier to run or just adds one more bottle with a familiar ingredient on it.

What it actually does well

  • Exceptional hydration
  • Effective barrier support
  • Fragrance-free and suitable for sensitive skin
  • Plumping and soothing effects

Where it starts to feel redundant

  • May feel too rich for very oily skin types
  • The texture might not appeal to everyone

Routine fit

Where it belongs in the stack
