Pacifica Undercore Spot Serum Mask is a leave-on under-eye treatment designed to address dark circles and dehydration. Each single-use pack delivers a concentrated dose of vitamin C, a well-known brightening ingredient that helps visibly reduce the appearance of dark circles and uneven skin tone around the delicate eye area. The serum mask formula is lightweight and hydrating, working to plump and refresh the under-eye skin without leaving a heavy or greasy residue.

This product is suitable for most skin types, including sensitive skin, as it avoids harsh additives and focuses on gentle, plant-based ingredients. The mask is intended for targeted application: after cleansing, the serum can be patted gently under the eyes and left on without rinsing, allowing the active ingredients to absorb overnight or during the day as part of a skincare routine.

Pacifica formulates this under-eye treatment to be completely vegan and cruelty-free, meaning no animal-derived components are used and no animal testing is conducted at any stage of production. The packaging is minimal, with each pack providing a single treatment dose, making it convenient for travel or occasional use.

While results can vary depending on individual skin condition and consistent application, the formula aims to support a more rested and even-looking eye area over time. It does not promise instant or permanent changes but rather offers a gentle option for those seeking a vitamin C-based brightening and hydrating treatment for under-eye concerns.
