Citri•Nu Vitamin C Serum with Caffeine (15ml)

You get 20% L-ascorbic acid alongside caffeine citrate, witch hazel extract, beta-glucosamine, aminoguanidine, and a lightweight base of rice starch and glycerol. No synthetic fragrances, parabens, or fillers.

Caffeine citrate complements the vitamin C by adding a fresh, tightening feel when you apply it. Together they target multiple skin concerns in one step, so you're not layering separate products for brightness and firmness.

After cleansing and toner, use 1-2 pumps on your face, neck, chest, or backs of hands. Let it absorb for about 2 minutes, then follow with moisturizer or sunscreen if it's morning.

Yes, it's safe for daily use in both your AM and PM routines. In the morning, follow it with sunscreen to protect the active ingredients from UV breakdown.

You'll notice the caffeine's tightening feel right away. Broader improvements in tone and radiance build gradually with consistent daily use, and individual results vary.

The combination of vitamin C and witch hazel is designed to support a brighter, more even-looking complexion over time. Pair it with daily sunscreen, since UV exposure works against brightening progress.

It skips synthetic fragrances, parabens, and unnecessary fillers, and it's designed for all skin types. With 20% L-ascorbic acid though, it's a potent formula. If your skin runs reactive, patch test first and ease into daily use.

You're getting 20% L-ascorbic acid alongside caffeine citrate, witch hazel, and aminoguanidine. That combination isn't something you'll find in most serums, and the formula stays clean with no synthetic fragrances or parabens.

Most people tolerate it well. Discontinue use if you notice irritation, and avoid contact with eyes and broken skin. It's for external cosmetic use only.

Keep it in a cool, dark spot to preserve potency. L-ascorbic acid breaks down with heat and light exposure, so a medicine cabinet or drawer works better than a bathroom counter.
