Our take on the Spa Sciences Vitamin C Serum Brightening Facial Serum

Spa Sciences Vitamin C Serum is a gel-like facial serum built around vitamin C with ferulic acid and zeolite, aimed at brightening, firming and fading dark spots. It is fragrance-free, paraben-free and vegan, and the label calls it non-comedogenic and non-acnegenic, so it is pitched at sensitive and acne-prone skin as well as dry and mature skin. It is meant for morning and night use. At $9.99 at eBay as of November 5, 2026, it is the cheapest of the three stores listing it new, a low entry price for a vitamin C serum.

Questions and answers

Is $9.99 a good price for this serum?
It is the lowest of the three stores listing it new, at $9.99 at eBay as of November 5, 2026. That is a low entry price for a vitamin C serum, so it is a reasonable buy if you want to try the formula.
Can I use it if I have sensitive or acne-prone skin?
The label lists sensitive and acne-prone skin and calls it fragrance-free and non-comedogenic. Start once a day to check for stinging before moving to twice daily.
Morning or night?
The label says twice daily, morning and night. Vitamin C layers well in the morning under sunscreen, which also protects against the photo-aging it targets.
What actives does it contain?
Vitamin C is the main active, with ferulic acid and zeolite. It is free of parabens and fragrance and is vegan.
How long until I see brighter skin?
Vitamin C serums typically need several weeks of consistent use before dark spots and tone look better. Buyers report gradual smoothing rather than overnight change.
Does it help acne scars?
It is listed for acne scars and dark spots, and vitamin C can help fade post-acne marks over time. Deep or pitted scars are not something a serum fixes.

At eBay, for $9.99, 38% under what the other stores charge, as of our latest check.
