What Sephora says

What this product is supposed to do

A supercharged moisturizer with 10% THD Ascorbate Vitamin C that provides clinically shown, visible brightening results and targets signs of aging.

NormalDryCombinationand OilyDark SpotsFine Lines and Wrinklesand Dullness

Apply twice daily to face and neck with continued use.

For external use only.

Note: Due to the high potency of active ingredients, color may shift over time. This will not affect product performance.

What Glass adds

What actually matters before you buy it

This is a solid choice for someone looking to incorporate a high-potency vitamin C into their routine, especially if brightening and anti-aging are the primary concerns. Its rich texture makes it a good option for normal to dry skin, but it may be too heavy for very oily skin types. The inclusion of other antioxidants and hydrators adds to its appeal.

Best for

When this is a smart buy

  • Dull skin
  • Uneven skin tone
  • Signs of aging
  • Normal to dry skin types

Skip if

When this is the wrong lane

  • You have very oily skin and prefer a lighter texture
  • You are sensitive to high concentrations of Vitamin C

Routine fit

Where this fits in your routine

Apply this moisturizer after your serum and before sunscreen in the morning, or after cleansing and any treatment serums in the evening. It's designed to be the moisturizing step that also delivers active benefits.

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

  • High concentration of THD Ascorbate Vitamin C
  • Addresses multiple signs of aging
  • Brightens and evens skin tone
  • Suitable for most skin types

Where it starts to feel redundant

  • Can be rich for very oily skin
  • Potential for sensitivity due to high potency

Routine fit

Where it belongs in the stack

Morning and Night

This moisturizer can be used both morning and night. In the morning, it helps protect against environmental stressors, and at night, it works to repair and rejuvenate the skin.

FAQ

The fast answers people actually need

Is this moisturizer good for sensitive skin?

While it is fragrance-free and contains some soothing ingredients, it is a potent formula with a high concentration of Vitamin C. If you have very sensitive skin, it's recommended to patch test first or consult with a dermatologist.

Can I use this with other Vitamin C products?

It's generally not recommended to layer multiple high-potency Vitamin C products at the same time, as this can increase the risk of irritation. However, this moisturizer can be used in conjunction with other skincare steps that contain Vitamin C at different times of the day or on alternate days, depending on your skin's tolerance.

What is THD Ascorbate Vitamin C?

THD Ascorbate is a stable, oil-soluble form of Vitamin C that is known for its brightening and anti-aging benefits. It's often preferred for its stability and ability to penetrate the skin effectively.
