YOUN Beauty Vitamin C Face Serum 20% Sodium Ascorbyl Phosphate — Ferulic Acid & Hyaluronic Acid, Hydrating Antioxidant

YOUN Beauty 20% Vitamin C Face Serum is a high-strength antioxidant treatment that blends a stable vitamin C derivative with ferulic acid, vitamin E and hyaluronic acid to brighten, hydrate and protect the skin.

Designed for people who want a concentrated topical antioxidant without harsh additives, this serum uses 20% sodium ascorbyl phosphate — a stable, bioavailable form of vitamin C — paired with complementary actives to address dullness, moisture loss and environmental stressors. Packaged in an opaque glass bottle to limit oxidation, the formula emphasizes clean ingredients and broad skin compatibility.

How does this serum help brighten uneven, sun-affected skin?

The high-concentration sodium ascorbyl phosphate works with ferulic acid and vitamin E to neutralize free radicals and support a more even-looking complexion. While topical brightening results vary, the antioxidant blend helps reduce the visual effects of environmental damage over time.

• 20% sodium ascorbyl phosphate for stable vitamin C activity
• Ferulic acid and vitamin E boost antioxidant protection
• Opaque glass packaging reduces oxidation and preserves potency

Will this serum keep my skin hydrated without feeling heavy?

This formulation includes hyaluronic acid, jojoba oil and aloe vera to attract and retain moisture while maintaining a lightweight texture. The ingredients are selected to hydrate the skin surface and support the skin barrier without leaving a greasy residue.

• Hyaluronic acid draws and holds moisture at the skin surface
• Jojoba oil provides balanced emollience and non-greasy nourishment
• Aloe vera soothes and calms while supporting hydration

Is this serum suitable for sensitive or acne-prone skin?

The formula avoids parabens, added fragrance and common irritants, and includes centella asiatica to calm the skin. As with any active product, patch testing is recommended, especially for highly reactive skin, because high-strength vitamin C derivatives can cause temporary tingling for some users.

• Fragrance-free, paraben-free and vegan-friendly formulation
• Centella asiatica and aloe vera offer soothing support
• Start with a small amount and perform a patch test if sensitive

How should I add this serum into my daily skincare routine?

Use the serum after cleansing and toning but before heavier creams or oils; apply a few drops to dry skin and follow with moisturizer and sunscreen during the day. For beginners, alternate nights or use every other day to build tolerance before increasing frequency.

• Apply 1–3 drops to cleansed face, then press gently into skin
• Use daily in the evening or in the morning followed by SPF
• Store in a cool, dark place to maintain product stability
