Wearing sunscreen every day is not only the best way to protect your skin from harmful UV rays, but it also prevents you from getting skin cancer, dark spots, and wrinkles over time. However, most people don’t know that there are two different kinds of sunscreen to help forestall premature aging. These two types include physical sunscreens and chemical sunscreens.
Physical sunscreen is a lotion or cream that contains compounds such as zinc oxide and titanium dioxide that work by sitting on the surface of your skin to deflect UV rays away from your body with a reflective barrier. Zinc oxide-based sunscreens work like a shield and are currently the only sunscreen recommended by the Food and Drug Administration (FDA) for use on babies.
Benefits of Physical Sunscreen
These mineral-based sunscreens are ideal for people with sensitive skin because they do not contain any harsh or irritating chemicals, and they are less likely to clog your skin. Titanium dioxide and zinc oxide are the only sunscreen ingredients that are generally recognized as safe and effective by the FDA.
Additionally, these kinds of sunscreens last longer in direct UV light and start working the moment they are applied, so you do not need to apply them before going out into the sun to reap their full benefits. Physical sunscreens also tend to have a longer shelf life.
Cons of Physical Sunscreen
Although physical sunscreens provide numerous benefits for your skin by blocking out harmful UVA and UVB rays, they do have some downfalls as well, such as:
- Rinses or rubs off easily, especially while sweating, meaning more frequent re-application may be necessary
- Can leave a white film or chalky residue on the skin, and certain formulas are not compatible with darker skin tones
- May not provide adequate protection if not applied properly across your skin
- Chemical Sunscreen

Chemical sunscreens also protect your skin from UV rays. However, this type of sunscreen works by absorbing UV rays. Often, chemical sunscreens contain ingredients such as oxybenzone, octinoxate, and avobenzone. When light hits the skin, these chemicals in the sunscreen create a chemical reaction where UV rays are converted to heat, which then dissipates from the skin.
Benefits of Chemical Sunscreen
Unlike physical sunscreens, chemical sunscreens are quick and easy to apply due to their thinner consistency. You also require less chemical sunscreen to protect the skin because you do not have to reapply as frequently since chemical sunscreens last longer.
Cons of Chemical Sunscreens
Due to the chemicals in these lotions, chemical sunscreens may irritate or cause reactions in people who have highly sensitive or acne-prone skin. The higher the SPF, the more likely it is that the sunscreen will irritate sensitive skin types. In addition, chemical sunscreens require at least 15 to 20 minutes prior to sun exposure for the sunscreen to begin working. Many chemical sunscreens are also marketed as water-proof; however, it is still recommended to reapply after excessive sweating or going in water.
