LPF Liquid contains light liquid paraffin, which softens and rehydrates dry skin, and is also used in conditions such as contact dermatitis, atopic dermatitis, senile pruritus, and ichthyosis. It is generally safe as a moisturiser, but long-term use without medical review is not advised, as persistent dry skin can have various causes, and some may require proper treatment. A doctor or dermatologist can check your skin, confirm whether long-term use is suitable for you, and guide you on safe moisturisers based on your condition.
