Prime Day Deal: TruSkin’s Best-Selling Vitamin C Serum Is 25% Off

Brit+Co Staff on June 20, 2026

If you’ve wanted to add a vitamin C serum to your routine but weren’t sure where to start, TruSkin’s best-seller is an easy, low-risk entry point — gentle enough for sensitive skin and one of the most-reviewed serums on Amazon. For Prime Day, the 1 oz bottle is 25% off.

The deal

For Prime Day — June 23–26, 2026 — the 1 oz bottle of TruSkin Vitamin C Facial Serum is 25% off, down to $14.99 (from $19.99). It’s a Prime Day deal, so a Prime membership is required, and the price ends when the event closes on June 26 (or earlier if it sells out). The 1 oz is the perfect size to try it before committing to the bigger bottle.

What it is

It’s a brightening vitamin C facial serum that uses Sodium Ascorbyl Phosphate (SAP) — a stable, skin-friendly form of vitamin C that’s gentler than straight L-ascorbic acid and effective down to the last drop. It’s blended with hyaluronic acid to hydrate, plus vitamin E, aloe vera, witch hazel and MSM. TruSkin markets it for the look of dark spots, fine lines and uneven tone, for all skin types, and it’s cruelty-free. This is the 1 fl oz (30 mL) size.

How to use it

After cleansing, apply up to one dropperful to your face, neck and the backs of your hands, up to twice daily, then layer moisturizer on top. A morning application under sunscreen gives you antioxidant support through the day. Because the SAP form is gentle, it’s a forgiving place to start with vitamin C — but if your skin is reactive, begin once a day and build up.

Who it’s for

It’s for first-timers and sensitive-skin types who want vitamin C’s brightening benefits without the sting some stronger formulas cause — and the small 1 oz bottle and low Prime Day price make it an easy, low-stakes trial. If you already know you love it and go through serum quickly, the 2 oz value bottle is the better cost-per-ounce buy.

Frequently asked questions

When is the Prime Day deal?
The 25% discount — down to $14.99 (from $19.99) — runs during Amazon Prime Day, June 23–26, 2026. A Prime membership is required, and the price ends when the event closes (or earlier if it sells out).
Is it good for sensitive skin?
It’s formulated to be gentle — it uses Sodium Ascorbyl Phosphate, a stable, milder form of vitamin C, alongside soothing aloe and hydrating hyaluronic acid. As with any active, patch-test and start slowly if your skin is reactive.

Same formula in both. The 1 oz (30 mL) is the lower-commitment size to try it; the 2 oz (60 mL) is the better per-ounce value for regular users.
