Sun damage to the skin is primarily caused by ultraviolet (UV) radiation from the sun. Sunscreens that contain SPF (Sun Protection Factor) work by blocking or absorbing these UV rays, which can help to prevent sunburn, skin aging, and skin cancer.
SPF works by creating a barrier on the skin that reflects or absorbs UV radiation from the sun. There are two types of UV radiation that can damage the skin: UVA and UVB. UVA rays penetrate deep into the skin and are responsible for causing premature aging, wrinkles, and age spots, while UVB rays cause sunburn and are the primary cause of skin cancer.
SPF is a measure of how well a sunscreen can protect the skin against UVB rays. For example, an SPF 30 sunscreen will block about 97% of UVB rays, while an SPF 50 sunscreen will block about 98% of UVB rays. However, it’s important to note that no sunscreen can block 100% of UV rays.
Regular use of SPF can help to prevent sun damage to the skin, including sunburn, premature aging, and skin cancer. However, it’s important to use sunscreen properly and to reapply it regularly, especially when spending time outdoors. We carry Zo Skin care line that offers multiple sunblocks.

Retinol and Retin A (Tretinoin) are a class of Vitamin A derivatives that have many benefits in skin. They are known for their anti-aging benefits. One of the ways that they can help to treat sun damage is by increasing cell’s turnover and promoting the growth of new, healthy skin cells.
When skin is exposed to UV radiation from the sun, it can cause damage to the skin cells, leading to the development of dark spots, fine lines and wrinkles, and uneven texture. Vitamin A derivatives can help to counteract this damage by encouraging the skin to shed its outermost layer of dead skin cells more quickly, revealing fresher, brighter skin underneath. They also have brightening effects by suppressing melanin production in the skin.
Tretinoin/Retinol can also help to stimulate the production of collagen, which is a key protein that gives skin its strength and elasticity. As we age and our skin is exposed to sun damage and other environmental stressors, collagen production naturally decreases, leading to the development of fine lines and wrinkles. By promoting collagen production, Tretinoin can help to improve skin texture and firmness.
Vitamin C, Hydroquinone, Kojic acid are also highly recommended for treatment of sunspots and hyperpigmentation.
