This firming serum from medicube is formulated for use on both the face and neck. It combines NAD+, EGF peptide, and collagen to support the appearance of skin firmness and elasticity. The product is designed to address visible signs of aging, including wrinkle appearance, loss of elasticity, and enlarged pores.

NAD+ is a coenzyme naturally present in the body that plays a role in cellular energy metabolism. EGF (epidermal growth factor) peptide is included to support skin renewal and repair processes. Collagen is added to help maintain skin structure and hydration. The formula aims to provide targeted care for areas that commonly show early signs of aging, such as the jawline, neck, and cheek area.

The serum has a lightweight, non-greasy texture that absorbs relatively quickly into the skin. It is suitable for daily use in a skincare routine, applied after cleansing and before moisturizing. The product comes in a 1.01 fl.oz (30 ml) bottle with a pump dispenser for controlled application.

This anti-aging serum is intended for individuals looking to incorporate a concentrated treatment into their regimen. It can be used on normal, combination, and dry skin types. Those with sensitive skin should review the full ingredient list before use, as active peptides and other components may vary in tolerance.

The product is part of medicube’s Korean skincare range and is formulated with a focus on functional ingredients rather than added fragrances or dyes. It does not claim to deliver immediate or permanent results, but rather to support the skin’s natural maintenance and improvement over consistent use. Regular application may help reduce the visibility of fine lines and improve overall skin texture around the face and neck area.
