SeoulCeuticals Vitamin C 20% Hyaluronic Acid Serum 1 oz — CE Ferulic‑Style Brightening & Anti‑Aging

SeoulCeuticals 20% Vitamin C Hyaluronic Acid Serum is a concentrated Korean-style facial serum that combines high-strength vitamin C, vitamin E, and ferulic acid with hyaluronic acid to brighten skin and help smooth the look of fine lines.

This 1 oz serum blends a 20% stabilized vitamin C derivative with complementary antioxidants and hydrating hyaluronic acid formulated in the style of CE Ferulic serums. It’s created for daily topical use as part of a morning or evening routine, aiming to deliver brighter-looking skin, improved texture, and more even tone without heavy residue. Lightweight and fast-absorbing, the formula layers well under sunscreen and makeup.

How quickly will I notice changes in my skin?

Visible improvements in radiance and texture often appear with consistent use over several weeks; many users report noticing a brighter complexion and softer-feeling skin after two to four weeks. Results depend on individual skin type, existing concerns, and application consistency.

• Use once daily in the morning for antioxidant protection under SPF.
• Expect gradual reduction in dullness and improved skin feel within weeks.
• For best results, apply to clean, dry skin before moisturizer.

What active ingredients are in this serum and why do they matter?

The formula centers on 20% vitamin C plus vitamin E and ferulic acid, a classic antioxidant trio that supports brighter-looking skin and helps stabilize vitamin C. Hyaluronic acid adds hydration and helps skin look plumper, while the lightweight base promotes absorption without greasiness.

• 20% vitamin C derivative for brightening and antioxidant support.
• Vitamin E and ferulic acid to stabilize and boost antioxidant performance.
• Hyaluronic acid for immediate surface hydration and smoother appearance.

Can I use this with other skincare or makeup?

The serum is designed to integrate into multi-step routines: apply after cleansing and before heavier creams or oils. It pairs well with sunscreens in the morning and with gentle hydrators at night; avoid layering with highly acidic exfoliants immediately after to reduce irritation risk.

• Layer under SPF for daytime antioxidant benefit and sun protection support.
• Use with mild cleansers and non-irritating moisturizers for best tolerance.
• Avoid combining with strong AHAs/BHAs in the same application without patch testing.

How should I store and apply the serum for maximum stability?

Vitamin C products are light- and air-sensitive; store the bottle in a cool, dark place and keep the cap tightly closed. Use the dropper to dispense a few drops onto fingertips, pat gently onto face and neck, and follow with moisturizer.

• Store upright in a cool, shaded area away from direct sunlight.
• Apply 3–5 drops to face and neck after cleansing and toning.
• Replace the cap immediately to limit air exposure and maintain potency.

Who is this for: This serum is aimed at adults seeking a robust antioxidant step in their skincare—ideal for those wanting to address dullness, uneven tone, early visible signs of aging, or dryness without a heavy texture. It suits normal to dry and combination skin types that tolerate vitamin C; sensitive skin users should patch-test first. Use consistently as part of a balanced routine alongside sunscreen for daytime protection and to support the product’s brightening and smoothing benefits.
