The TruSkin vitamin C serum is worth buying if harsher vitamin C products have left your face red and tight. It uses sodium ascorbyl phosphate, a stable form of vitamin C, in a 2 fl oz bottle with hyaluronic acid and vitamin E. Buy it if you want brightening without the sting.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
Sodium ascorbyl phosphate instead of straight L-ascorbic acid is the whole reason this one works for sensitive faces. Two ounces, unscented, no parabens or dyes. If other vitamin C serums have burned you, this is the gentler lane.
Buy if you:
- react to stronger vitamin C formulas with redness
- are working on dark spots and uneven tone
- want hyaluronic acid and vitamin E in the same bottle
- prefer unscented, dye-free skincare
Skip if you:
- want a high-percentage L-ascorbic acid serum, this is the milder form
- expect dark spots gone in a week
- need a fragranced serum you can smell

The Form of Vitamin C Is the Story
Most vitamin C serums sting because L-ascorbic acid is inherently acidic, the lower the pH, the more effective, and the more your face hates you for it. TruSkin sidesteps that by using sodium ascorbyl phosphate, a phosphate salt that converts to active vitamin C on your skin rather than arriving pre-loaded for a fight. It’s a thin, clear liquid, nothing sharp in the smell, nothing aggressive on application. You can see today’s price here.
The Dropper Bottle Annoyance
Glass dropper bottles are fiddly. You’re unscrewing a cap over a wet sink with one hand, every single morning, and 2 fl oz is a lot of mornings. No pump here. It’s a genuine friction point.
What People Get Wrong Before They Buy
Gentler does not mean weaker results, it means slower comfort. Sodium ascorbyl phosphate is designed to hold potency over time rather than hit hard on day one. Brightening and tone work is a weeks-not-days project, and anyone expecting an overnight fade will be disappointed in the product for the wrong reason.
Storing It and Making It Last
Keep it out of the sun and cap it tight, sodium ascorbyl phosphate is more stable than L-ascorbic acid, but it’s not invincible, and a hot windowsill will turn any vitamin C serum orange and useless. On dosage: three to four drops covers a full face, which means a 2 oz bottle runs two to three months at daily use. That’s the whole math on value.
Who the TruSkin Vitamin C Serum Actually Suits
Sensitive skin that’s been burned before, that’s the buyer. The dermatologist-tested, cruelty-free credentials are table stakes at this price point; what actually matters is that the formula skips the ingredients most likely to cause a reaction: no fragrance, no dyes, no parabens. If you’ve abandoned vitamin C serums because they wreck your skin barrier, this is the version worth revisiting. If you want a 15% L-ascorbic acid hit, it won’t deliver, full stop.
Pros
- Stable vitamin C form aimed at lower irritation
- Hyaluronic acid, vitamin E, aloe and jojoba in the same formula
- Unscented, paraben-free, dye-free, cruelty-free
- 2 fl oz bottle lasts a long time at a few drops per use
Cons
- Glass dropper, no pump, awkward one-handed
- Milder vitamin C form won’t satisfy high-percentage seekers
- Tone and spot work takes consistency, not days
Frequently Asked Questions
Should I patch test it first?
Yes, on your inner arm or jawline for a day. It’s formulated to be low-irritation and it’s free of parabens, dyes and sulfates, but aloe and jojoba are still botanicals some people react to. Cheap insurance.
Can I layer it with retinol or sunscreen?
Serum goes on first, sunscreen over it in the morning. Lots of people keep retinol for nights and vitamin C for mornings to avoid stacking actives. If your skin runs reactive, alternate rather than layer.
What if it doesn’t work for me?
There’s a 30-day refund or replacement policy. That’s shorter than most skincare needs to show tone results, so start using it the day it arrives rather than letting it sit in a drawer.
