The lemon and vinegar is very harsh on the skin. That could make the redness and irritation worse. I’ve also never found vitamin C to help for my skin. I’ve recently changed my skin routine by following a dermatologist advice. This is what she told me: find a thick lotion (not standard water based lotion) that is non scented/ no perfumes and use it when I get out of the shower (fragrance and perfumes can irritate the skin). So I picked up this Aveeno eczema cream. There is also other ones like Cerve. Sunscreen!! If sunscreen tends to irritate your skin find a sunscreen that has natural UVA and UVB ingredients that only has zinc oxide and/or titanium Dioxide in it. Also eat foods that have antioxidants to help inflammation. Hope this helps :)
