Cetaphil Vitamin C Serum for Sensitive Skin, 1 oz — Niacinamide Brightening & Hydrating

Cetaphil Vitamin C Serum is a gentle, dermatologist-tested brightening serum that helps visibly reduce dark spots and even skin tone while hydrating and defending sensitive skin.

This lightweight 1 oz formula combines stabilized Vitamin C, Niacinamide (Vitamin B3) and Sunflower Seed Oil to deliver antioxidant protection, hydration and tone correction without fragrance, parabens or pore-clogging ingredients. Designed for sensitive skin, the serum aims to improve luminosity, reduce the look of hyperpigmentation and support the skin’s moisture barrier with 24-hour hydration properties. It’s non-comedogenic, hypoallergenic and clinically proven to give multiple benefits in a single, easy-to-apply step.

How does this serum help with dark spots and uneven tone?

The formula uses Vitamin C to target visible dark spots and surface discoloration while Niacinamide helps promote a more uniform skin tone. Together these act to reduce the appearance of hyperpigmentation and restore a brighter overall complexion over continued use.

• Stabilized Vitamin C targets surface free radicals and discoloration.
• Niacinamide supports skin-brightening and tone-evening effects.
• Clinically proven reduction in the appearance of dark spots with regular use.

Is this safe for sensitive or reactive skin?

Cetaphil formulated this serum to be gentle: it’s fragrance-free, hypoallergenic and dermatologist tested to minimize irritation risks. It’s also non-comedogenic and free of parabens, making it suitable for many sensitive skin routines when used as directed.

• Fragrance-free and paraben-free to reduce common irritants.
• Hypoallergenic, dermatologist tested for sensitive skin compatibility.
• Lightweight, non-greasy texture that absorbs quickly without clogging pores.

How should I use it in my daily skincare routine?

Apply a few drops to clean, dry skin in the morning and/or evening before moisturizer. Because Vitamin C can increase sun sensitivity, pair morning application with a broad-spectrum sunscreen for daytime protection and optimal results.

• Use 2–3 drops on face and neck after cleansing and before moisturizer.
• Morning users should follow with SPF to protect treated skin.
• Consistent daily use improves tone, texture and luminosity over weeks.

What additional skin concerns does this serum address?

Beyond brightening, the serum supports hydration and helps reduce the look of fine lines and rough texture. Sunflower Seed Oil helps condition and lock in moisture for up to 24 hours, while antioxidant activity protects against environmental stressors that can accelerate visible aging.

• 24-hour hydration support helps maintain the skin’s moisture barrier.
• Antioxidant protection defends against surface free radicals.
• Helps visibly reduce fine lines and smooth skin texture with regular use.

Who is this for: Cetaphil Vitamin C Serum suits anyone looking to brighten dull skin, fade the appearance of dark spots or strengthen a sensitive-skin routine without added fragrance or harsh additives. If you have reactive or easily irritated skin but want antioxidant protection, tone correction and lightweight hydration in one product, this serum offers a balanced, dermatologist-tested option to add into morning or evening regimens.
