I had never suffered with overly dry lips before last month. Then things started to change, and I thought it was because I'd been using lip liners nearly every day for the last few months, despite always using a lip balm before bed and applying any lip colour. I started increasing the amount I was using my trusty Blistex Intensive Moisturiser, but even that wasn't doing much. The skin around my lips also started to become sore and dry, and I tried multiple products, but they only helped a little. I even tried the cream version of the product below, but the texture isn't suitable for lips, and it's not as long lasting. So, about a week ago, I began applying Epaderm ointment to them at night, and once or twice during the day, and they're back to normal.
Epaderm ointment is an emollient for eczema, psoriasis, and other dry skin conditions. It's fragrance, colour, and SLS free, and can be applied anywhere to the body. The smallest tub is 125g/£6.89, so if you're only applying it to small areas, it's going to last a long, long time. I've scooped some out and put it in a little pot to make it more convenient to use/travel with.
If you suffer from dry, chapped lips, I'd recommend giving this a try. And if you've suffered with these symptoms in the past, I'd love to know what you've used to help them.
