XIANUI Deep Vitamin Radiance Serum — 5% Niacinamide & Stabilized Vitamin C, 1.01 fl. oz — Brightening, Hydrating Barrier Repair

This serum blends a multi-ingredient radiance complex with a soothing licorice-root base and barrier-repair actives to target dullness, uneven tone, and surface dehydration without heavy texture or strong fragrances. Its formula layers easily under moisturizers and makeup and is designed for regular use on sensitive and reactive skin thanks to calming extracts and dermatologist testing.

How does this serum improve dull or uneven-looking skin?

The formula pairs 5% niacinamide with tranexamic acid, glutathione, and 3-O-ethyl Vitamin C to address visible unevenness and restore a fresher-looking complexion. Together these actives support a more even surface appearance while working gently to avoid irritation.

• 5% niacinamide helps reduce the look of discoloration and refines skin texture.
• Tranexamic acid specifically targets visible dark patches and uneven tone.
• Stabilized Vitamin C (3-O-ethyl) plus glutathione support radiance without high acidity.
• Licorice root extract soothes and calms for a less reactive brightening process.

Will this serum hydrate and strengthen my skin barrier?

Yes—the product combines Ceramide NP, squalane, and a triple hyaluronic acid complex to hydrate multiple skin layers and support barrier resilience. These ingredients help skin feel plumper and more comfortable while reducing moisture loss over time.

• Ceramide NP restores essential lipids that reinforce the skin barrier.
• Squalane provides lightweight, lasting emollience without greasiness.
• Triple hyaluronic acids (varied molecular weights) deliver both surface and deeper hydration.

How does the texture and everyday use feel under skincare or makeup?

The serum is formulated for fast absorption and a non-sticky finish, making it simple to layer into morning or evening routines. It’s intended to sit comfortably beneath creams and sunscreens and won’t interfere with makeup application.

• Silky, fast-absorbing liquid that melts into skin.
• Non-greasy finish suitable for combination or oily skin types.
• Works well as a step before moisturizers and SPF in the AM or alone under night creams.

Is this safe for sensitive or reactive skin?

The base uses licorice root extract as a calming foundation and avoids artificial fragrances and harsh preservatives to reduce irritation risk. Dermatologist-tested and formulated for low irritation, it’s designed to be compatible with sensitive skin, though patch testing is recommended for highly reactive individuals.

• Fragrance-free, minimizing common irritation triggers.
• Licorice root extract soothes while active brighteners work gradually.
• Dermatologist-tested formulation aimed at low irritation profiles.

Who is this for: XIANUI Deep Vitamin Radiance Serum is intended for anyone seeking a non-irritating, multitasking brightening serum that also replenishes hydration and supports the skin barrier. It suits those with dull or uneven-looking skin, people who prefer fragrance-free daily actives, and users who want a lightweight product that layers easily with other skincare and sunscreen. If you have very reactive skin, perform a patch test first and introduce it gradually into your routine.
