How does liquid paraffin work?
Liquid paraffin leaves an oily protective layer that limits water loss, helping soften and moisturise the skin. This bath formulation disperses the emollient through the water so affected skin is coated while bathing.
How to take liquid paraffin
For external use in bath water only. Follow the product instructions for the quantity appropriate to the bath.
Shake the bottle before use.
Add it to bath or wash-basin water rather than swallowing or applying it as an oral product.
Immerse affected areas or gently sponge them with the treated water.
Pat the skin dry rather than rubbing.
Take care getting in and out, and clean greasy surfaces afterwards with detergent.
