This product set includes the VT COSMETICS Reti-A Reedle Shot 100 serum in a 1.69 fl oz bottle and four sheets of the Reti-A Reedle Shot 100 2-Step Hydrogel Mask. The serum contains a formulation that combines retinol (reti-a) with micro-sized reedle particles, which are designed to create temporary micro-channels on the skin's surface. This mechanism is intended to facilitate the delivery of the retinol and other active ingredients into the skin, potentially improving the efficiency of the treatment. The serum has a lightweight, fluid texture that absorbs without leaving a sticky residue. It is suitable for those who are exploring retinol-based skincare and are looking for a way to enhance product penetration without aggressive physical exfoliation. The 2-step hydrogel mask follows a similar principle: the first step applies a concentrated retinol and reedle shot essence to prepare the skin, and the second step covers the face with a hydrogel sheet that locks in moisture and soothes. The hydrogel mask is formulated with hydrating and calming ingredients to counterbalance the potential dryness associated with retinol use. Both products are intended for use on normal to combination skin types, and those with sensitive skin should perform a patch test before full application due to the presence of retinol and the micro-puncturing action of the reedle particles. The regimen is best used in a nighttime routine, followed by a moisturizer and sunscreen during the day. The products focus on a non-invasive approach to improving skin texture, fine lines, and overall radiance through gradual, controlled exposure to retinol combined with physical micro-channeling.
