This refill pack from SKINN is designed for the Deep Wrinkle Face Serum, offering a concentrated intensive age reset treatment for the face. The formula incorporates collagen, vitamin C, retinol, and NAD to support the skin’s natural renewal process while addressing visible signs of aging such as fine lines and wrinkles. The serum is intended to deliver hydration and brightness, contributing to a more even skin tone and a smoother overall complexion.

The inclusion of retinol aids in promoting cell turnover, which can help reduce the appearance of deeper expression lines over consistent use. Vitamin C works to support the skin’s radiance and defend against environmental stressors, while collagen and NAD are added to help maintain skin firmness and elasticity. The lightweight, hydrating texture is suitable for daily application as part of an anti-aging skincare routine.

This product is well suited for individuals looking to address multiple signs of aging, including loss of firmness, uneven texture, and dullness. It is appropriate for normal, combination, and dry skin types, although those with sensitive skin may wish to introduce retinol gradually. The refill pack format allows users to replenish their serum supply without purchasing a new full bottle, which can help reduce packaging waste and offer a more economical option for continued use.

To use, apply a small amount to clean, dry skin after cleansing and before moisturizer, avoiding the eye area. Consistent application over several weeks may help support the skin’s smoothness and luminosity. As with any product containing active ingredients, a patch test is recommended before full use.
