The obvious priority is immediate discontinuation of any further topical corticosteroid use. Protection and support of the impaired skin barrier is another priority. Eliminating harsh skin regimens or products will be necessary to minimize potential for further purpura or trauma, skin sensitivity, and potential infection. Steroid Atrophy   is often permanent, though if caught soon enough and the topical corticosteroid discontinued in time, the degree of damage may be arrested or slightly improve. However, while the accompanying Telangectasias may improve marginally, the Striae is permanent and irreversible. 
Please remember that each skin care product may work differently for different people. Some may find significant, immediate and prolonged relief for itch, while others find mild to moderate relief and yet others may not see any benefits. Likewise, some may find a product that deliver tremendous skin improvement after 2 weeks of use, others may seen a similar benefits after 6-8 weeks. Of course, there are those who just need to find alternative products for relief. That is why you need to try and find the products that work for you.
