NURIO Gentle Vitamin C Serum

Brighten Without the Drama

Vitamin C serums have a reputation for being finicky—unstable formulas that oxidize quickly, irritating concentrations that make your skin red and sensitive, or sticky textures that pill under sunscreen. If you've tried vitamin C before and been disappointed, you're not alone.

NURIO Gentle Vitamin C Serum takes a quieter, more balanced approach. It uses two complementary forms of vitamin C—L-ascorbic acid for proven brightening efficacy and magnesium ascorbyl phosphate for gentle, stable support—alongside ferulic acid to enhance antioxidant protection and stability. The formula is rounded out with soothing botanical extracts (rice, calendula, chamomile) that keep skin comfortable and hydrated during daily use.

This isn't marketed as a hero product because it doesn't need to be. It's simply a well-formulated, effective vitamin C serum that does what it should: support brighter, more even-toned skin with antioxidant protection, without irritation or complexity.

What's Inside:

• L-Ascorbic Acid — The gold-standard form of vitamin C, clinically proven to support skin brightness and collagen synthesis. L-ascorbic acid is effective but can be irritating at high concentrations. This formula uses a balanced level that delivers results while remaining gentle enough for daily use.
• Magnesium Ascorbyl Phosphate — A more stable, gentler form of vitamin C that converts to ascorbic acid in the skin. It provides similar brightening and antioxidant benefits with less potential for irritation, making it ideal for sensitive skin or those new to vitamin C. The dual-C approach ensures both immediate and sustained vitamin C activity.
• Ferulic Acid — A plant-derived antioxidant that stabilizes vitamin C and enhances its photoprotective benefits. Ferulic acid works synergistically with ascorbic acid to neutralize free radicals and support the skin's defense against environmental stressors. It also helps the formula remain stable and effective over time.
• Rice Extract — Rich in antioxidants, amino acids, and vitamins that support skin brightness and hydration. Rice extract has a long history in Asian skincare for promoting a luminous, even complexion.
• Calendula Extract — A soothing botanical known for its calming properties. Calendula helps reduce redness and supports skin comfort, balancing the active vitamin C components.
• Chamomile Extract — Gently soothes and calms skin. Chamomile's anti-inflammatory properties make this serum comfortable for daily use, even for those with reactive or sensitive skin.
• Glycerin — A humectant that draws moisture into the skin, ensuring the serum hydrates while it brightens. This prevents the dryness sometimes associated with vitamin C products.

What It Does:

• Supports skin brightness and radiance
• Helps even skin tone and reduce the appearance of dark spots
• Provides antioxidant protection against environmental stressors
• Gentle enough for daily morning use
• Layers smoothly under moisturizer and sunscreen
• Soothes and hydrates with botanical extracts
• Dual vitamin C forms for balanced efficacy and gentleness

Who It's For:

Anyone seeking a reliable, gentle vitamin C serum to complete their morning skincare routine. Those who want antioxidant protection and gradual brightening without irritation. People who've had negative experiences with harsher vitamin C formulas. Existing NURIO customers looking to add a complementary AM serum to pair with evening treatments. Anyone building a science-informed routine who values quality formulation over marketing hype.

What You'll Notice:

The serum has a lightweight, silky texture that absorbs quickly without leaving residue or stickiness. It layers beautifully under moisturizer and sunscreen with no pilling. Your skin feels hydrated and comfortable immediately after application. Over weeks of consistent use, skin appears brighter and more even-toned. The overall complexion looks more radiant and healthy. This is gentle, cumulative improvement—not dramatic overnight transformation.

How to Use:

Apply 2-3 drops to clean, dry skin each morning. Gently press into face and neck, avoiding the eye area. Allow to absorb for 30-60 seconds before applying moisturizer and sunscreen. Use daily for best results.

Pro tip: Vitamin C works best in the morning when your skin needs antioxidant protection against daily environmental exposure. Always follow with SPF.

What Makes This Different:

Most vitamin C serums choose between efficacy and gentleness. This formula balances both by using two complementary forms of vitamin C—one for proven results, one for stability and comfort. The addition of ferulic acid enhances both the antioxidant benefits and the formula's longevity. Soothing botanicals ensure daily use is comfortable, not irritating.

This serum isn't positioned as the "strongest" or "most potent" vitamin C on the market. It's formulated to be effective, gentle, and reliable—a serum you'll actually use every day because it works well with your routine, not against it.

Dual vitamin C. Ferulic acid. Soothing botanicals. Daily antioxidant support.

WEEK 1-2: COMFORTABLE DAILY USE

In the first weeks, your skin adjusts to the vitamin C without irritation or sensitivity. The dual-form approach (L-ascorbic acid + magnesium ascorbyl phosphate) ensures your skin receives antioxidant support while the soothing botanicals (chamomile, calendula) keep it comfortable. You'll notice the serum integrates seamlessly into your morning routine—it absorbs quickly, layers well under moisturizer and sunscreen, and doesn't cause redness or peeling. Your skin may feel slightly more hydrated and plump from the glycerin and rice extract. This foundation phase establishes tolerance and prepares your skin for the brightening benefits to come.

WEEK 3-4: SUBTLE RADIANCE EMERGES

Around the third or fourth week, your complexion begins to look more radiant and refreshed. The vitamin C is supporting your skin's natural brightness, and the antioxidant protection is helping defend against daily environmental stressors. You might notice your skin has a healthier, more even appearance—not a dramatic transformation, but a subtle improvement in overall tone and clarity. Morning dullness diminishes slightly. Your skin looks more awake and vibrant.

WEEK 6-8: EVEN TONE BECOMES VISIBLE

With consistent daily use, skin tone appears more even and balanced. Minor discolorations, sun spots, or post-breakout marks may begin to fade gradually. The dual vitamin C forms are working cumulatively to support skin's natural brightening processes. Overall complexion looks more uniform and refined. This is gentle, progressive improvement—the kind you notice when comparing photos from two months ago, not overnight. The ferulic acid's antioxidant support is helping protect against new pigmentation from forming.

WEEK 12+: CUMULATIVE BRIGHTNESS & PROTECTION

After three months of daily use, the cumulative brightening effects are evident. Skin maintains a more radiant, even-toned appearance. Dark spots or uneven pigmentation have faded noticeably. Your complexion looks healthier and more luminous overall. The ongoing antioxidant protection from vitamin C and ferulic acid helps defend your skin against environmental aging—pollution, UV exposure (when paired with SPF), and oxidative stress. This is maintenance and prevention as much as correction: your skin is protected daily while looking brighter and more balanced.

ONGOING USE: SUSTAINED RADIANCE & DEFENSE

With continued daily application, vitamin C becomes a cornerstone of antioxidant protection in your routine. Skin maintains its improved brightness and even tone. New pigmentation forms more slowly because your skin is better protected. The serum continues to support your skin's resilience against environmental stressors. This is the long-term value of consistent vitamin C use: not just brightening, but ongoing defense that helps your skin age more gracefully.

Important Notes:

• Consistency matters. Vitamin C works cumulatively—daily morning use delivers the best results. Sporadic use yields sporadic benefits.
• Always pair with SPF. Vitamin C provides antioxidant protection, but it doesn't replace sunscreen. Use broad-spectrum SPF 30+ every morning after applying this serum.
• Results are gradual, not dramatic. This is a gentle, balanced formula designed for comfortable daily use and progressive improvement—not aggressive overnight transformation.
• Store properly. Keep the bottle tightly closed and away from direct sunlight to maintain vitamin C stability and efficacy.
• Pair with evening treatments. Vitamin C is ideal for morning use (antioxidant protection). Pair with NURIO retinol or peptide products in the evening for comprehensive anti-aging support.
