Sunscreen can work in two ways: first, by reflecting or blocking light from the skin; and second, by absorbing ultraviolet energy and preventing it from entering the skin cells. No sunscreen will give you 100% SPF protection, but products with SPF 30 and SPF 50+ can shield your skin from 96% to 98% of UVB (burning) rays.
We spoke to LeeAnne, a Trainer at Alpha-H about the sun and it's after effects: "There is no escaping the fact that unprotected UV exposure is by far the single most ageing thing we can do to our skin and causes visible negative change. It degrades both Hyaluronic acid and Collagen production as well as directly stimulating the Melanocyte to produce (most often unevenly) pigment, resulting in hyper-pigmentation. Human skin is also an excellent record keeper and stores every moment of sun exposure to manifest at a later time."
Sunblock has an important impact on the appearance, health, and quality of your skin. For this reason, we’ve asked some dermatologists and skincare experts to recommend their favourite sunscreens. These experts have recommended a range of high-quality broad-spectrum and noncomedogenic sunscreens that work effectively without irritating your skin. Find out more about keeping your skin protected from harmful UV rays in our Ultimate Guide to Sunscreen.
These sunscreen recommendations are based on scientific research and clinical experience, and aim to remove marketing jargon by focusing on ingredients and their effects. This way, you can choose a sunscreen that will carefully protect your skin, because it’s too important to take for granted!
