Difference Between Physical And Chemical Sunscreens

By now, all of you already know how essential it is to wear sunscreen daily. And that realization has thankfully led to a lot of women and men to protect their skin from the damages that come with sun exposure. Sunscreen has now the most integral part of morning skincare routine and I couldn’t be happier for everyone who’s doing their best to protect their skin.
Now that everyone has realized the importance of sunscreens, another important question arises; what type of sunscreen should you be using? There’s a lot of debate going on about physical and chemical sunscreens. So, I’ve decided to help you choose the best sunscreen for your skin.
Physical Sunscreen:
Physical sunscreens get their name because they act as a physical barrier against the UV rays from the sun. The sunscreen acts as a shield and does not allow the UV rays to get into your skin and actually ends of deflecting them away from your skin. Physical sunscreens also are known as mineral sunscreen because of the active mineral ingredients that it contains. The two active mineral ingredients, zinc oxide and titanium dioxide have the only ingredients that have been labelled as safe by the FDA.
Let’s take a look at the pros and cons of physical sunscreens.
Pros:
• Starting with the pros, physical sunscreens are broad-spectrum. They can protect you from both UVA and UVB rays.
• Physical sunscreens instantly come into action. You don’t have to wait 15-30 minutes for it to start doing its work.
• Has the active ingredients that actually are approved safe by the FDA.
• Because of the white layer that appears on the skin, it’s really easy to tell if your sunscreen is coming off.
• If the skin doesn’t get sweaty or wet, physical sunscreens last longer in the UV light exposure as compared to chemical sunscreens.
• Physical sunscreen is extremely suitable for those who have sensitive skin since it doesn’t allow the heat to absorb.
• It’s really beneficial for acne-prone and oily skin since it does not clog the pores.
• Have a longer expiration date than chemical sunscreens
Cons:
• The sticky white layer that usually accompanies almost every mineral sunscreen may not be appealing to some.
• You have to apply it frequently especially if you’re sweating because it can rub off.
• A thin layer won’t do. For physical sunscreen to work effectively, you have to apply it properly all over your face.

Chemical Sunscreen:
Chemical sunscreens can also be called organic sunscreens because they contain organic chemicals that absorb the UV rays and convert them into heat which is then released. Most of the sunscreens found in the pharmacies are usually chemical sunscreens. Many people avoid chemical sunscreens fearing that it might penetrate their skin, but it should be noted that it’s not the skin that absorbs the ray but the chemicals in the sunscreen themselves.
Pros:
• Chemical sunscreens are more efficient when it comes to application. They are thin and elegant which feels good to wear on the skin especially when you’re wearing makeup.
• You don’t have to apply it generously. A small amount will go a long way.
• They don’t feel sticky at all.
• Chemicals can get into your skin, but it has been studied that they are not harmful at all.
Cons:
• The most vital con I’ve learned about chemical sunscreens is that 12 out of 16 ingredients have not been labelled safe by the FDA. The most worrisome of all is oxybenzone. Oxybenzone has potential to disturb hormone levels and may cause endometriosis. It is not only a risk of humans but is also harmful to the coral reefs in the ocean because it is not biodegradable, that is why it is banned in a lot of places like Huawei and Virgin Islands.
• Chemical sunscreens have been known to irritate the skin and eyes as well which is not good for people with sensitive skin.
• May even cause your brown spots to get worse because of all the heat being made in the skin.
• Requires time ranging from 15-30 minutes to start doing its job after being applied.
• Chemical sunscreens are not as long-lasting as physical sunscreens. They have to be frequently applied throughout the day.
• Some chemical sunscreens may cause acne-prone skin to breakout.
• It is not suitable for people with sensitive skin and the higher the formula of SPF, the worse irritation and redness can get for them.
That’s all from me about physical and chemical sunscreens so now all of you can weigh the pros and cons according to your skin and choose the sunscreen best fit for your skin and your daily routine. And please don’t forget to do a patch test before applying a new sunscreen on your face.
