Image result for Xeroderma From the post “how to buy the right sunscreen for your acne-prone skin” we learned that UVA and UVB cause sunburns and damaging effects such as skin cancer. One of the solution to prevent skin problems is sunscreen. Sunscreen operates by blending organic and inorganic active ingredients. Inorganic or Mineral ingredients such as zinc oxide or titanium oxide reflect or scatter ultraviolet (UV) radiation. Organic ingredients like octyl methoxycinnamate (OMC) or oxybenzone absorb UV radiation and disseminate it as heat. Ideally, we want to choose sunscreens that protect us from both of the two types of damaging UV radiation such: UVA and UVB. Organic ingredients are your chemical sunscreens, and in rare cases, the chemical ingredients in Chemical sunscreens cause skin reactions such as acne, burning, blisters, dryness, itching, rash, redness, stinging, swelling, and tightening of the skin. These reactions are most commonly associated with para-aminobenzoic acid (PABA)-based sunscreens and those containing benzophenones. Some sunscreens also contain alcohol, fragrances, or preservatives, and should be avoided if you have skin allergies or acne-prone skin. The physical sunscreens contain titanium dioxide and zinc oxide which reflect, scatter, and absorb both UVA and UVB rays. These ingredients, produced through chemical processes, do not typically cause allergic reactions. Physical sunscreen use to leave a thick white film on the skin. Now, using new technology, the particle sizes of zinc oxide and titanium dioxide have been subdued, making them more transparent without losing their ability to screen UV. The following table lists these ingredients and includes information regarding regarding which UV protection they provide Image result for FDA approved sunscreen Here is a list of 6 amazing zinc oxide sunscreen for your acne prone skin
