Topical Therapy for Skin Conditions

Emollients and Moisturizers

The British Association of Dermatologists recommends water-in-oil emollients be applied three to eight times daily for dry skin conditions, with 200-400g needed weekly for adequate coverage 1, 2
Emollient types, such as lotions (e.g., Eucerin intensive, E45 Lotion, Aveeno lotion), creams/gels (e.g., Diprobase cream, Epaderm cream, Doublebase gel), and ointments (e.g., White soft paraffin, yellow soft paraffin, emulsifying ointment), are recommended for different skin conditions 1, 2, 3
Soap substitutes, including Aqueous cream, Doublebase emollient shower gel, and Oilatum bath/shower products, are suggested for skin care 2, 3

The American Academy of Dermatology recommends topical corticosteroids for inflammatory skin conditions, with different potencies based on severity 4, 5
Mild corticosteroids, such as Hydrocortisone 1% and Daktacort, are recommended for mild inflammatory skin conditions 2, 5
Moderate to potent corticosteroids, including Eumovate, Trimovate, Betnovate, and Elocon, are suggested for more severe inflammatory skin conditions 2, 5
Application technique involves applying corticosteroids thinly once or twice daily to affected areas, using ointment formulations for dry skin and creams for weeping areas 5

The American Academy of Dermatology recommends benzoyl peroxide (2.5-10%) as first-line treatment for mild to moderate acne 4
Topical retinoids are recommended for comedonal acne and maintenance therapy 4
Clascoterone is a newer topical treatment for acne 4
For EGFR inhibitor-induced rash, topical antibiotics (e.g., clindamycin 2% or erythromycin 1%) are recommended for grade 1 rash, while combination therapy is suggested for grade 2-3 rash 6, 7

The British Association of Dermatologists recommends cleaning the affected area before applying ointments 1, 5
Emollients should be applied in a downward direction to avoid folliculitis 2, 3
For inflammatory conditions, corticosteroids should be applied thinly once or twice daily 5
For severe mucosal involvement, white soft paraffin ointment and potent topical corticosteroid ointment are recommended 9, 10

Underuse of emollients can lead to inadequate skin care, while overuse of potent steroids can cause skin atrophy and systemic effects 2, 3, 4, 5
Using creams instead of ointments for very dry skin conditions can be ineffective 1, 5
Discontinuing treatment too early can lead to recurrence of skin conditions 4, 5
Using topical antibiotics as monotherapy increases the risk of resistance 6, 7
