Tips/Home remedies for pre-holiday skin

I'm going on holiday in around 6 weeks and my skin is not having a good time. I have small/medium lesions of plaque psoriasis across my body. Though I know steroid creams work wonders I hate the effects of the thinning of the skin & I don't really like using chemicals on my skin. If anybody has any tips to help lessen the lesions i.e. any home remedies people have found useful or products that help would be amazing!! I have anxiety and find it difficult to see my GP/Dermatologist and need a quick fix !
