Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns. As per your complain it seems that you have get repeated sun burns and brownish appearance is due to hyperpigmentation and redness is due to inflammation of skin.. The first thing that you should do is to do cool compresses over the skin.. It will help in reducing inflammation and sooth the skin..You can also apply alovera gel by cooling it in refrigerator and it will help in soothing skin ans well as has antibacterial and anti-inflammatory properties.. Calamine lotion can also help.. Once the skin starts becoming normal you can start applying depigmenting creams containing Kojic acid glycolic acid and arbutin.. You can also take steam bath and can gently exfoliate your skin with a towel.. You can also scrub your skin every alternate day with a body scrub.. Avoid excess sun exposure and always apply sunscreen lotion when exposed to sun.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
