Metacell Renewal B3

SkinCeuticals Metacell Renewal B3 is a comprehensive daily emulsion formulated to visibly improve the appearance of early signs of photoaging. Utilizing a patent-pending aqueous delivery system, this lightweight formula delivers a high concentration of 5% niacinamide (vitamin B3), a firming 2.5% tripeptide concentrate, and 15% pure glycerin to address the multiplicative effects of photoaging — increasing cell turnover to resurface skin, reclarify and even skin tone, and improve the appearance of wrinkles and surface elasticity.

What sets Metacell Renewal B3 apart is its innovative non-disruptive delivery architecture. Traditional methods of delivering niacinamide to the skin can disrupt the skin’s barrier and counteract its moisturizing and protective benefits. SkinCeuticals’ research labs developed a new delivery system that optimizes niacinamide’s efficacy on skin while simultaneously reinforcing the barrier — free of ingredients that traditionally occlude the skin’s barrier, allowing niacinamide to work at its full potential. The result is a comprehensive daily emulsion that delivers intense hydration without a heavy or tacky feel, suitable for all skin types.

Skin Types

Suitable for all skin types including dry, normal, oily, combination, and sensitive. Particularly beneficial for those in their 20s and 30s beginning to notice early signs of photoaging such as uneven skin tone, mild discoloration, and the first appearance of fine lines and loss of surface elasticity.

Skin Concerns

Formulated to address early signs of photoaging including sensitized and dehydrated skin, discoloration, blotchiness, uneven skin tone, fine lines, and loss of surface firmness and elasticity. Ideal for those seeking a proactive, comprehensive daily treatment that addresses multiple early aging concerns simultaneously.

Benefits

• Promotes skin renewal by increasing cell turnover to resurface and refine skin texture
• Reduces the appearance of discoloration, blotchiness, and uneven skin tone
• Strengthens and reinforces the skin’s moisture barrier with a non-disruptive niacinamide delivery system
• Improves the appearance of skin firmness and surface elasticity with a firming tripeptide concentrate
• Delivers intense hydration with 15% pure glycerin without a heavy or tacky feel
• Lightweight emulsion texture suitable for daily use on all skin types

Key Ingredients

• 5% Niacinamide (Vitamin B3) — Extensively studied for over 30 years within the dermatological and scientific community, niacinamide is a multi-functional vitamin with proven benefits for photoaging. It helps reduce the appearance of skin discoloration and blotchiness, strengthens the skin’s moisture barrier, and supports overall skin tone evenness. Delivered via SkinCeuticals’ patent-pending non-disruptive aqueous emulsion, niacinamide is optimized for maximum efficacy without compromising the skin’s barrier integrity.
• 2.5% Firming Tripeptide Concentrate — A targeted blend of powerful peptides that works to reduce the look of fine lines and improve the appearance of skin firmness and surface elasticity. Peptides signal the skin to support its structural proteins, helping to restore a more youthful, resilient appearance over time with consistent use.
• 15% Pure Glycerin — A classic and highly effective humectant with powerful water-binding properties that attract and retain moisture at the skin’s surface. At 15%, glycerin delivers intense, long-lasting hydration without the heavy or tacky feel associated with richer moisturizers — making it ideal for daily use across all skin types, including oily and combination skin.

The Science Behind It

Photoaging — the visible aging caused by cumulative UV and environmental exposure — manifests differently depending on skin biology, lifestyle, geography, sun protection behaviour, and skincare regimen. While these signs may appear at different intensities from person to person, they have a multiplicative effect on the skin’s appearance, creating a prematurely aged look that can be difficult to address with single-ingredient treatments. Metacell Renewal B3 was developed to tackle this complexity head-on, combining three clinically proven actives in a single daily emulsion that addresses the full spectrum of early photoaging signs simultaneously.

The formula’s patent-pending delivery architecture is central to its efficacy. By resolving the traditional limitation of niacinamide delivery — which can disrupt the skin’s barrier when delivered via conventional methods — SkinCeuticals has created a system that optimizes niacinamide’s multi-factorial benefits while reinforcing rather than compromising the skin’s protective barrier. This makes Metacell Renewal B3 uniquely effective as both a corrective and a barrier-supportive daily treatment.

How to Use

Twice daily, massage 1–2 pumps of Metacell Renewal B3 into a thin, even layer onto the entire face, neck, and chest. In the morning, apply after a SkinCeuticals antioxidant serum and before a broad-spectrum sunscreen — daily SPF is essential to protect against further photoaging and to maximize the results of this treatment. In the evening, apply as the final step after any corrective serums or treatments in your regimen.
