As someone who tests beauty products for a living, I think it takes a really good product to stand out. That said, there’s a formulation that I always go back to, and it’s now 55% off on Amazon.

Pound the alarm, grab your credit card — do whatever you have to do to make sure you grab the TruSkin Vitamin C Serum in time. After reviewing dozens of these brightening boosters throughout the years, this product has earned the mark of best overall in our vitamin C serums review.

It works wonders on my skin, but I’m not the only one who sings its praises. The formula is an Amazon best-seller with more than 147,000 gleaming reviews. Not to mention, it’s one of Kyle Richards’ sworn-in products.

Fit for sensitive skin users with its fragrance-free formulation, this serum absorbs quickly and is now at one of the best prices *ever*.

It’s your lucky day, too. The serum, which is currently 45% off on Amazon, is its lowest price with our exclusive discount. Use promo code NYPVITC10 at checkout to reap an additional 10% off — that’s 55% off total — and enjoy the product for less than $20.

Its benefits are versatile, appealing to a variety of skin types and textures. For one, it serves as a dark spot corrector to help reverse hyperpigmentation when used consistently. It also helps diminish the appearance of fine lines and wrinkles, making it a lovely precursor to your favorite night cream.

Additionally, its formula is comprised of top-notch ingredients, including organic aloe vera, witch hazel, and jojoba oil. This trifecta helps hydrate and soothe the skin, preventing the irritation that can sometimes accompany potent serums. It never causes redness or flare-ups of my skin, which is saying something as my skin is severely sensitive.

If your skin is dry, the TruSkin Vitamin C Serum works overtime to hydrate and replenish your skin barrier, and that’s all thanks to hyaluronic acid. FYI, this ingredient is the *best* for drawing moisture into the skin. While I have combination skin, this formulation is the ideal boost I need to help avoid the flakiness that likes to (annoyingly) show up near my ear, nose and T-zone. For this reason, applying this serum allows my full-coverage foundation or tinted moisturizer to layer onto my skin beautifully.

I could write a love letter about this serum, but the main point is this: the TruSkin Vitamin C Serum is 100% worth buying on sale.

Its benefits, cosmetic elegance and splendor make it a fantastic option to include in your skincare routine. Buy it now, thank me later.
