Three Forms of Vitamin C, Not Just One

Three Forms of Vitamin C, Not Just One

Standard vitamin C serums typically rely on a single form of the ingredient, often ascorbic acid alone — which can be genuinely unstable and irritating for sensitive skin. Dr. Barbara Sturm's The Good C Vitamin C Serum takes a more considered approach, combining three distinct, skin-friendly forms specifically chosen to work together.

A genuinely proprietary three-form vitamin C blend

The serum specifically combines oil-soluble Vitamin C THD, stabilised synthetic Vitamin C in glucosidic form, and plant-based Vitamin C — rather than relying on a single form that may be less stable or more irritating on its own.

Kakadu plum as a genuinely potent natural source

The formula includes an extract from kakadu plum — a fruit that contains 100 times the vitamin C concentration of an orange, a concrete, specific comparison rather than a vague "superfruit" claim.

Zinc specifically included to boost absorption

Zinc is deliberately included to help activate and transport vitamin C effectively into the skin — a targeted delivery mechanism rather than simply adding more vitamin C and hoping for better absorption.

A stable, optimal 5% concentration

The serum is formulated at 5% vitamin C — specifically chosen as a concentration stable enough for gentle, easy absorption without damaging skin barrier function or inducing sensitivity, a genuine balance rather than maximising potency at the expense of comfort.

Aloe vera and hyaluronic acid for genuine hydration alongside brightening

Beyond pure vitamin C function, the serum includes aloe vera and hyaluronic acid specifically for intensive moisture and hydration — addressing hydration and brightening simultaneously rather than treating them as separate skincare steps.

Genuinely flexible, layerable use

The Good C Vitamin C Serum can specifically be mixed with other Dr. Barbara Sturm serums, drops, or moisturisers — flexible enough to slot into an existing routine rather than requiring a complete regimen overhaul.

A considered sustainability detail

As part of ongoing sustainability testing, the product specifically ships without cello foil — a small but genuine packaging reduction consistent with broader environmental consideration.

An honest, balanced independent review

It's worth being direct: one independent reviewer specifically noted the serum's milky, non-traditional consistency felt moisturising and soothing, but didn't deliver quite the visible "glow" they'd hoped for — genuine, specific feedback rather than uniformly glowing praise, reflecting that individual results can vary with vitamin C serums generally.

At a glance

Who it suits

This serum suits anyone wanting a genuinely gentle, well-formulated vitamin C serum targeting uneven pigmentation and dullness without the irritation risk some single-form vitamin C products carry. Anyone specifically wanting maximum vitamin C potency above gentleness should compare this against higher-concentration ascorbic acid serums, since Dr. Sturm's formula is deliberately calibrated toward tolerability rather than pure strength.
