Bur-marigold is well known in home skin care, and the product information specifically mentions external use of the infusion for baths, rubdowns and care of skin areas prone to irritation. This makes it suitable for people who prefer a single-ingredient herbal preparation without fragrances, colourants or unnecessary additives in their care routine.
For external use, prepare an infusion and allow it to cool to a comfortable temperature before applying it to the skin or adding it to bath water. For a rubdown, use clean material such as cotton or gauze and avoid rubbing aggressively; the aim is gentle care and comfort, not exfoliation. For baths, the infusion can be added to the water as part of a simple soak.
If you have sensitive skin or have not used bur-marigold before, try it first on a small area and wait to see how your skin responds. Do not apply herbal infusions to broken skin, and use a freshly prepared infusion rather than keeping it for a long time, as water-based herbal preparations are not preserved like finished cosmetics.
