Greetings, @jada1!
I’m sorry to hear that you have been struggling with a skin condition. Sending good thoughts and love your way! 
I’m afraid I’m not very familiar with CARP, but I have always had sensitive skin and have suffered from bouts of eczema- I would be happy to share the magickal and holistic remedies that have worked for me 
Green Witchery for skin conditions:
Calendula- an absolute life-saver for my eczema. This soothing herb can be applied as a balm to sore, dry, and inflamed skin for long-lasting healing.
@Silverbear has a wonderful video about Calender and it’s herbal and magickal properties here:
Lavender a lovely herb with a wide variety of uses, commonly found in skin products. Some believe lavender is able to heal scarred skin and helps to soothe anxiety. Culinary lavender can be added to foods or enjoyed as a soothing tea.
You can learn more in the discussion Lavender or search the many spells and rituals that invoke the properties of this helpful herb.
Other spells for healing:

Please keep in mind that what works for one body may not work for someone else- we are all wonderfully unique! Before applying anything to your skin or taking medicine internally, it would be wise to check with a doctor who is qualified to give advice about your specific medical situation
I hope that some of this information can help you find a path towards finding relief from your skin disease.
Happy healing and blessed be!
