Overview
COSRX's Good Morning cleanser is a low pH gel face wash built around BHA, sold in a 5.07 fl oz size and positioned by the brand as a daily, mild cleanser for sensitive skin.
Low pH gel cleansers are designed to clean without disrupting the skin's natural acid mantle the way traditional soap-based washes can, which is the main idea behind COSRX's pH-balancing claim. There's no seller description or ingredient attribute data provided for this listing beyond the title itself.

Performance notes
The core mechanism is the low pH gel base combined with BHA, intended to cleanse while keeping the skin's surface pH closer to its natural range than a standard soap cleanser would. This is the reasoning behind daily use on sensitive skin, though no further formulation detail is provided in this listing.
