The spray is designed for skin that feels warm, dry or tight after sun exposure. It works best on clean skin, so the most practical moment is after a shower following a day outdoors or swimming. Salt, chlorine, sand and sunscreen residue can stay on the surface and make a new layer feel less comfortable, so washing first helps the product spread evenly.
Hold the bottle far enough from the body to cover the area with a mist, then spray a thin layer over your shoulders, back, chest and legs. You can spread it lightly with your hand if you want, but you do not need to massage it in for a long time. The formula is deliberately light and non-occlusive, so a thin film that dries down without a heavy residue is enough.
Reapply as often as needed, especially after towelling dry, sweating or going into water again. Because it is a spray, it is easier to use over large areas than a thick balm on hot skin. Keep it away from the eye area. If you want to use it on the face, spray a little into your hand first and pat it on, avoiding the eyes. If the skin is badly burned, blistered or unusually reactive, do not try to treat it with cosmetic products; seek appropriate advice first.
