**4. Conclusions**

Psoriasis is a chronic skin condition characterised primarily by dysfunctional skin barrier integrity, dry and itchy skin, and the development of scaly plaques. Being defined as a multifactorial skin condition caused by an interaction between various genetic and environmental factors, psoriasis requires a 1-2-3 step-ladder combination approach of therapeutics to treat the condition and topical moisturisers to alleviate the symptoms.

Therapeutics like topical corticosteroids are not moisturisers themselves, but benefit from having a moisturising base and fundamental and complimentary moisturising ingredients. Therefore, understanding the interplay and synergism amongst different ingredients as well as being familiar with their advantageous biophysical effects and potential adverse effects is essential to get a range of cosmetically acceptable and/or therapeutically stable products with desired impact on both healthy and psoriatic skin.

Topical moisturisers are a key part of psoriasis management and come in various formulations such as lotions, gels, creams and ointments. By using such formulations readily and frequently, the patient can remain on a daily maintenance regimen that aims for continuous hydration of the skin as well as improvements in skin's functionality, structural strength, visual and tactile attributes as well as minimisation of dryness and itchiness.
