What is this product?

A soothing trouble-care ampoule built on houttuynia cordata water, with niacinamide fifth on the list and salicylic acid listed at 1,000 ppm for gentle blemish care.

What makes it different?

The base is houttuynia cordata flower/leaf/stem water at 825,367 ppm, so the formula is water-led rather than oil-led. Salicylic acid is printed at 1,000 ppm, a low printed level that suits daily calming use. Centella components including asiaticoside, asiatic acid, madecassic acid and madecassoside sit in the later part of the list alongside multiple hyaluronic acid derivatives and ceramides NP, AP and EOP. The list shows no added fragrance, no essential oils and no drying alcohols according to the reference screening.
