Naturium Vitamin C Complex Face Serum, 2 oz Jumbo — L‑Ascorbic Acid, Hyaluronic Acid Hydration & Anti‑Aging

Naturium Vitamin C Complex Face Serum Jumbo is a concentrated 2 oz antioxidant serum designed to hydrate skin and visibly reduce the look of fine lines and wrinkles with stable L-ascorbic acid, Kakadu plum, hyaluronic acid, and vitamin E.

This jumbo-size facial serum combines a potent vitamin C complex with hydrating and protective co-ingredients to support a brighter, smoother-looking complexion. The formula pairs pure, stable L-ascorbic acid and Kakadu plum—one of the richest natural sources of vitamin C—with hyaluronic acid for immediate hydration and vitamin E to help maintain skin comfort. It’s formulated in the USA, dermatologist tested, and created to be skin-compatible for many skin types.

How does this serum help brighten and smooth skin?

The high concentration of a vitamin C complex aims to support more even-looking skin tone and the appearance of smoother texture. L-ascorbic acid and Kakadu plum deliver antioxidant activity while hyaluronic acid adds moisture to plump the skin surface.

• Contains stable L-ascorbic acid for potent antioxidant support.
• Kakadu plum enriches natural vitamin C content.
• Hyaluronic acid provides immediate hydration and temporary plumping.
• Vitamin E helps maintain skin comfort and supports formula stability.

When and how should I use the Naturium Vitamin C Complex Serum?

Apply a thin, even layer to cleansed face, neck, and chest once or twice daily, avoiding the eye area. For daytime use, follow with a moisturizer and broad-spectrum sunscreen to protect vulnerable skin exposed to sunlight.

• Use morning and/or evening after cleansing and before moisturizing.
• Patch-test if you have sensitive skin or are new to vitamin C serums.
• Layer under sunscreen in the morning for daily protection support.

Is the jumbo size right for me and what results can I expect?

The 2 oz jumbo bottle is ideal for regular users who want to extend their routine without frequent repurchasing. In a controlled clinical study, users saw improved appearance of fine lines and wrinkles over weeks; individual results vary by skin type and consistency of use.

• Jumbo 2 oz supply reduces need for frequent replacement.
• Clinically observed improvements in study participants over a multi-week period.
• Best results with consistent application plus sun protection.

Is this serum suitable for sensitive or reactive skin?

The formula is designed to be skin-compatible and is free from parabens and many common irritants, but vitamin C can still provoke sensitivity in some people. A patch test is recommended before full-face application, and starting every other day can help skin acclimate.

• Vegan, cruelty-free, paraben-free, gluten-free, and dermatologist tested.
• Most Naturium products are synthetic fragrance-free to reduce irritation risk.
• Patch-test and introduce gradually if you have reactive skin.

Who this is for: This vitamin C serum jumbo is aimed at people seeking an affordable, science-minded antioxidant treatment to support brighter, more hydrated-looking skin. It suits individuals who want a concentrated vitamin C option with added hyaluronic acid and vitamin E, those preferring larger bottle sizes for value, and users willing to incorporate daily sunscreen and gradual introduction if they have sensitive skin.
