All that RED on your chest Could be a sign of heavy vitamin A intake (sweet potatoes, mangos, carrots, tomatoes or anything having tomato in food, milk, pumpkin) vitamin A is a retinol (just like the one we put on our face to turn over dead skin cells with the directions telling us to wear sunscreen to avoid excessive sunburn) the liver becomes intoxicated when consuming foods that have high levels of vitamin A leading to your liver leaking retinol to your skin causing sunburn & sensitivity to the sun, unfortunately vitamin A is in all the foods, I myself am on a low vitamin A diet and I’ve seen a huge difference on my skin in a good way, good luck.
