How Curatory Credit works

Why I chose it

When there isn’t a reason not to use one, I see an antioxidant as a foundational morning step. I chose this as the higher-strength L-ascorbic acid option for people who want vitamin C alongside hydration and very gentle surface exfoliation.

It is suitable for most skin types, including sensitive skin. It may not be the best option if your skin is very sensitive or reactive, or if richer vitamin C serums tend to make you break out. In that case, a different form of vitamin C, rather than a weaker product, may suit you better.

The ingredients that make this special

A closer look at the ingredients doing the most meaningful work in this formula—and what the evidence can reasonably tell us.

Ascorbic acid

The most studied form of topical vitamin C, used for antioxidant support.

Read the clinical context

L-ascorbic acid is the most studied form of topical vitamin C. In the right formulation, it provides antioxidant support and over time can help improve the appearance of uneven tone and some signs of sun exposure. If your skin normally finds stronger vitamin C serums sting, a different form of vitamin C may suit you better.

Gluconolactone

A PHA that gently exfoliates and helps the skin hold onto water.

Read the clinical context

Gluconolactone is a polyhydroxy acid, or PHA, that gently exfoliates and helps the skin hold onto water. It’s usually gentler than stronger AHAs. In a rinse-off cleanser it mainly supports gentle cleansing, while a leave-on product gives it more time to work.

Green Tea Extract

A botanical ingredient that provides additional antioxidant support.

Read the clinical context

Green tea extract contains antioxidant polyphenols and may also help the skin look calmer. It’s best thought of as a supporting ingredient within the wider formula.

Feverfew Extract

A botanical antioxidant included to support the wider formula.

Read the clinical context

Feverfew extract provides additional antioxidant support. Small studies suggest it may help the skin look calmer, but here it mainly works alongside vitamin C and green tea.

More about NeoStrata

NeoStrata grew from the work of dermatologists Dr Eugene Van Scott and Dr Ruey Yu, whose research helped establish alpha hydroxy acids in modern skincare. The brand has continued to develop acid-based technologies, including polyhydroxy acids, alongside antioxidant, pigment-supporting, moisturising and sun-protection formulas.

Its heritage is useful context, but the role and tolerability of each finished product still matter more than the brand story.
