I agree with everyone. Stripping back to a basic skincare routine of a cleanser and moisturiser (SPF 30+ in the AM) will reduce the risk of dermatitis again. Ensure your products are not expired and introduced them back one by one after patch testing. The way I do it is apply inside the elbow wait 12-24 hours, then behind the ear and wait 48 hours, then proceed with caution. Once a week for a few weeks and increase it one day at a time. Remeber, it can take around 12 weeks to see results but also in this time it can cause a reaction. All the best!
