What Sephora says

What this product is supposed to do

A hydrating serum with a 75 percent Hyaluronic Acid Complex to help plump the look of skin with moisture for a dewy, youthful-, healthy-looking glow.

Normal and DryFine Lines and WrinklesDrynessand Dullness

Apply serum to face and neck twice daily with continued use. For external use only.

What Glass adds

What actually matters before you buy it

A straightforward hydrating serum. It does what it says it will do: hydrate. If your primary concern is dryness or a lack of plumpness, this is a reliable choice. It doesn't offer much beyond basic hydration, so don't expect it to tackle multiple concerns.

Consistent hydration

Users appreciate the reliable and consistent hydration this serum provides, making their skin feel softer and look more supple.

Dewy finish

Many reviewers mention the desirable dewy finish, which contributes to a healthy-looking complexion.

Best for

When this is a smart buy

  • Dry or normal skin types
  • Anyone seeking a hydration boost
  • Users concerned with fine lines and dullness

Skip if

When this is the wrong lane

  • You have oily or acne-prone skin and are sensitive to richer textures
  • You are looking for a serum with multiple active ingredients for concerns like acne or hyperpigmentation

Routine fit

Where this serum fits in

Apply this serum after cleansing and toning, and before your moisturizer. It's an excellent step to add hydration before sealing it in with a richer cream.

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

  • Intense hydration
  • Plumps skin
  • Lightweight texture
  • Suitable for dry and normal skin

Where it starts to feel redundant

  • Single-focus on hydration
  • Higher price point for a basic hydrator
  • May not be suitable for very oily skin

Routine fit

Where it belongs in the stack

Morning and Night

This serum can be used both morning and night. In the morning, it provides a hydrating base for makeup. At night, it helps replenish moisture lost throughout the day.
