This is a body and bath cosmetic, not a medical product. Use it only externally in bath water, and do not apply it to broken, scratched, freshly shaved, irritated or otherwise damaged skin. Mineral-rich bath products can feel intense on compromised skin, and a bath that is pleasant on normal skin may sting if the skin barrier is already disturbed.
If your skin is very sensitive or you have reacted to mineral baths before, keep the first session short and use a conservative amount rather than making the bath very concentrated. Pay attention to sensations during the soak: mild warmth from the bath is expected, but persistent stinging, itching or discomfort is a reason to leave the bath and rinse with clean water.
Avoid contact with the eyes and do not swallow the solution or bath water. Keep the bottle out of reach of children, and store it closed between uses so the product remains clean and easy to handle. If you use several bath products at once, be cautious with strong fragrances, scrubs or active cosmetic products on the same day, as combining too many stimuli can make sensitive skin less comfortable.
