For a standard-sized bath, you can start with a few generous handfuls (roughly 100-200 grams) dissolved under running warm water—not boiling hot, especially if your skin is sensitive. The salt will fully dissolve, leaving the water clear with a subtle juniper scent. Soak for 15-20 minutes to allow your skin to benefit from the minerals.
Since this is a fairly active bath product, it's thoughtful to avoid using it on broken or freshly irritated skin. If you have a significant skin condition or are sensitive to strongly scented products, it's wise to check suitability first. Many people use it after exercise or a demanding day as part of a relaxing ritual. You can follow the bath with a body scrub or a rich cream, as softened skin often feels more receptive. Store the bag in a dry place to prevent clumping.
