What the gurus are saying

The denatured alcohol and fragrance in this formula create a split verdict: gurus cite clinical support for oxidative stress, while others flag these ingredients as potentially irritating. At £16 it's affordable, though those with sensitive skin may want to patch-test first given the alcohol.

"L'Oreal also has some good Vitamin C options that have been shown to clinically support oxidative stress."

"It's the L'Oreal Vitamin C. The positives of this product are actually the price point is at £16, but it's in a pipette. It's 12% ascorbic acid, plus they added in denatured alcohol and fragrance. So unfortunately that product is a hardener."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
