PRODUCT DETAILS

Hello, focused breakout care. This lightweight, leave-on serum brings breakout care and post-breakout mark support into one focused step. It’s designed for acne-prone and sensitive skin, with oily and combination skin in mind when clogged pores or excess oil are part of the picture.

The formula pairs niacinamide with succinic acid to care for pimples and breakouts while improving the look of post-breakout pigmentation and uneven texture. Salicylic acid adds gentle exfoliation for pore buildup, blackheads and whiteheads. The serum also targets excess sebum.

That clarifying focus comes with a softer side. Panthenol and Ceramide NP provide soothing care and barrier support after exfoliation. The serum is also described as non-comedogenic, a useful detail when pore congestion is on your mind.

On skin, expect a lightweight texture that absorbs quickly. It’s a thoughtful fit when you want targeted care for breakouts and congestion without turning your routine into a project.
