Innbeauty Project Pro C Serum 15% Vitamin C, Fragrance-Free Brightening Serum with Ferulic Acid

INNBEAUTY PROJECT Pro C Serum is a lightweight, fragrance-free 15% vitamin C formula designed to brighten skin, reduce dark spots, and support a more even, youthful-looking complexion.

This serum blends a high concentration of active vitamin C with antioxidant ferulic acid in a fast-absorbing base so you can add targeted brightening to your daily routine without heaviness or fragrance. The formula aims to address uneven tone, surface discoloration, and early signs of aging while layering smoothly under moisturizers and SPF. It’s presented for routine use, twice daily or as tolerated, to support progressively clearer, more radiant skin.

How quickly will I see brighter skin after starting this serum?

Results vary by skin type and the condition being treated, but many users notice improved radiance and a fresher tone within a few weeks of consistent use. More noticeable reductions in dark spots or hyperpigmentation commonly take several weeks to months of regular application.

• Contains 15% vitamin C for a potent brightening effect.
• Visible radiance often after 2–4 weeks with continued use.
• Fading of deeper discoloration may require long-term consistency.

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

The fragrance-free, lightweight formula is designed to minimize irritation, but any high-strength vitamin C can cause tingling or sensitivity for some people. Patch testing and gradual introduction (every other day) can help determine tolerance.

• Fragrance-free to reduce potential scent-related irritation.
• Light, non-greasy texture layers well under other products.
• Start slowly and use sunscreen daily to protect treated skin.

How should I include this serum in my morning and evening routine?

Apply a few drops to clean, dry skin after cleansing and before moisturizer. In the morning, follow with a broad-spectrum SPF; at night, pair with a hydrating moisturizer or targeted repair product.

• Use 2–3 drops on face and neck for full coverage.
• Layer under moisturizer and always finish with SPF during the day.
• Introduce gradually if you have reactive skin, then use daily as tolerated.

What makes the formula different from other vitamin C serums?

This blend combines a high percentage of active vitamin C with ferulic acid, an antioxidant that helps stabilize vitamin C and enhance protection against environmental stressors. The fragrance-free, fast-absorbing base focuses on efficacy and wearability under daily skincare.

• 15% vitamin C concentration for stronger brightening potential.
• Contains ferulic acid to support antioxidant performance.
• Designed to be lightweight and compatible with layering in skincare routines.

Who this is for: Ideal for people seeking a potent, fragrance-free vitamin C serum to address dullness, uneven tone, and the early signs of aging. It’s well-suited to those who want a fast-absorbing product that layers easily under moisturizer and SPF. If you have very reactive skin, consider a patch test and gradual introduction; otherwise, this serum is a practical choice for daily brightening and antioxidant support.
