Is the $11.90 eBay price the full-size bottle?

Probably not. Full-size bottles of this serum normally cost far more, so confirm the volume in the listing before buying.

Can sensitive skin use it daily?

It is formulated for sensitive skin and many users apply it every morning. Start every other day and stop if stinging persists.

Why did my serum turn orange?

Vitamin C oxidizes when exposed to light and air. An orange or brown tint means it has lost potency, so store it closed and away from sunlight.

Can I use it with retinol or acids?

Use it in the morning and retinol at night to limit irritation. It already contains salicylic acid, so avoid stacking strong exfoliants on the same day.

Do I need sunscreen with it?

Yes. Vitamin C supports sun protection but does not replace it, and daily SPF is what preserves the brightening results.

Our take on the La Roche-Posay Pure Vitamin C10 Serum

A daytime face serum built around 10% vitamin C, with hyaluronic acid, salicylic acid and Neurosensine for hydration and comfort. It is marketed for sensitive skin and for dullness and early wrinkles, and it is oil-free and paraben-free. The best new price is $11.90 at eBay as of November 5, 2026, well below what this serum usually sells for at full size, so check the bottle size before buying.

What reviewers say

4.3 / 58,300 ratings

With about 8,300 ratings averaging 4.3 out of 5, most buyers report brighter, smoother skin within a few weeks and few reactions on sensitive skin. Complaints center on the thin, watery texture, the bottle darkening over time, and irritation for some.

What people mention

BrighteningPraisedBuyers say dullness fades and tone looks more even after several weeks of daily use.
SensitivityMixedMany sensitive-skin users tolerate it well, but some report stinging, especially with salicylic acid in the formula.
OxidationCriticisedOwners report the liquid darkening to orange before the bottle is finished, which they link to weaker results.
TextureMixedThe thin, watery serum absorbs fast for some and feels hard to apply evenly with the pipette for others.
HydrationPraisedHyaluronic acid gives a light moisture boost that sits well under sunscreen.
