SeoulCeuticals 20% Vitamin C Hyaluronic Acid Serum — 1 oz Brightening Antioxidant for Fine Lines & Hydration

SeoulCeuticals 20% Vitamin C Hyaluronic Acid Serum is a concentrated Korean-style antioxidant serum formulated to brighten skin, support collagen appearance, and hydrate for a smoother-looking complexion.

This lightweight 1 oz serum combines a high concentration of vitamin C with hyaluronic acid and CE-ferulic-style antioxidants to target dullness, uneven tone, and dehydration. Designed for daily use in morning or evening routines, the formula layers well under moisturizers and makeup and aims to improve visible texture and radiance when used consistently.

How does this serum help brighten and even skin tone?

The concentrated vitamin C acts as a potent antioxidant to reduce the look of pigmentation and promote a more luminous complexion over time. Combined with supporting antioxidants, it helps protect skin from environmental stressors that can contribute to dullness.

• 20% vitamin C concentration for noticeable brightening potential
• Antioxidant support modeled after CE Ferulic blends
• Targets sun spots and uneven tone with regular use

Will it hydrate and reduce the look of fine lines?

Hyaluronic acid in the formula draws and retains moisture in the skin’s outer layers, plumping the appearance of fine lines and improving surface smoothness. When layered into a regular routine, the combined hydration and antioxidant effect can make texture appear softer.

• Hyaluronic acid for multi-depth hydration
• Visibly plumps expression lines and crepey texture
• Absorbs quickly without heavy residue under makeup

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

The serum is formulated to be non-comedogenic and lightweight, which can suit many acne-prone routines, and the antioxidant blend is intended to support skin recovery appearance. Patch testing is recommended for sensitive skin due to the high vitamin C level.

• Non-comedogenic texture that layers beneath Korean makeup
• May help reduce appearance of acne marks with consistent use
• Patch test before full application if you have reactive skin

How do I use this serum in my daily skincare routine?

Apply a few drops to clean, dry skin after cleansing and toning, then follow with moisturizer and sunscreen in the morning. For evening use, pair with a restorative moisturizer; avoid combining with strong exfoliants on the same application to reduce irritation risk.

• Use once or twice daily depending on tolerance
• Layer under moisturizer and sunscreen for daytime wear
• Start with every-other-day use if new to high-concentration vitamin C
