Alison: Firstly, you may not be seeing a result if you follow a complicated routine or have tried a lot of different beauty products. So, I recommend going for the opposite and using a very simple routine.
Use L'Occitane 100% Shea Butter Lotion to clean the area and keep it hydrated. If your skin is dry because of an allergy or skin irritation, then this product should answer all your concerns. Any skin can react to the application of too many ingredients.
However, if your skin is flaky and eczema-like, you should follow a routine for sensitive skin. Cleanse and tone the area with Elemis S.O.S Cream at night and Daily Redness Relief in the morning. If you don't suffer from an infection and your skin needs conditioning, then this is a better routine for you. However, if your skin is angry, go for the L'Occitane Shea Butter. Simple!
