Is sunscreen Necessary throughout the year?
Yes, sunscreen is necessary throughout the year. We all know that three types of rays are coming from the sun UVA, UVB, and UVC. UVC rays never reach the earth so this is not a thing we should worry about. In UVB rays “B” means burn as it enters and damages our DNA.
Skin cells damaged by UVB rays accelerate inflammatory action in our body which results in sunburn or redness. UVB rays are stronger in summers as compared to winters.
On the other hand, UVA rays are the same throughout the year. Whether it’s summer or winter the harm caused by the UVA rays is equal. In UVA rays “A” means aging of the skin. These rays enter the dermis of the skin and cause damage to the collagen in cells which results in the fast aging of skin.
Comparison between Mineral and Chemical Sunscreen:
Mineral Sunscreen:
Physical sunscreen commonly refers as Mineral sunscreen. Most of the skin doctors prefer to use Mineral sunscreen. Zinc Oxide and Titanium Dioxide are the main ingredients of a Mineral sunscreen. Both ingredients are good at reflecting the UVA and UVB rays.
Pros:-
Skin-friendly:
The active ingredients Zinc oxide and Titanium Dioxide are generally easy on sensitive skin. People with sensitive skin or skin allergies are suggested to use mineral sunscreen. Because it is less likely to cause allergic reactions or irritation on the skin.
Save for acne-prone skin:
It is also very good for oily skin or acne-prone skin. It helps in reducing inflammation and regulates sebum. The ingredients in Mineral sunscreen are non-comedogenic. Even Zinc Oxide helps in improving the skin barrier.
More Efficient in Sun Protection:
The ingredients in the mineral formula are more efficient in protecting the skin from sun rays. They sit on the top of the skin prevent rays from absorbing into the skin layer and provide a physical barrier against UVA and UVB rays.
Cons:-
Unpleasant Texture:
The texture of mineral sunscreen is often recognized as thick and soft. It is not desirable to wear under make-up.
White Cast:
It is hard to spread on the skin’s surface. The ingredients in the mineral sunscreen (Zinc Oxide and Titanium Dioxide) are known to leave a white, chalky cast on the skin, especially on darker skin tones
Chemical Sunscreen:
It is well absorbed into our skin when applied. Chemical sunscreen uses UV filters like Oxybenzone, Avobenzone, Octinoxate, and Homoslate.
Pros:-
No White Cast:
Chemical sunscreens do not leave any white cast on the skin. Their formula is generally clear like gel, and it is easy to spread on the skin surface.
Easy to wear:
It does not feel heavy on the skin when applied. There are more advancements in chemical sunscreens as compared to mineral sunscreens. It is typically easier to handle on skin with or without makeup. It comes in different forms like creams, lotions, and sprays.
Cons:-
Less Effective:
It might be possible that chemical sunscreens are less effective as compared to mineral sunscreens. It works by converting the UV rays into heat after absorption, instead of physically blocking them from penetrating the skin. So, it is suggested that when you are looking for chemical sunscreen options look for SPF 30 or more to earn maximum sun protection.
Absorbed by the blood:
Some research shows that some of the chemical sunscreens when applied and absorbed by the skin, their ingredients were found in the blood sample and even urine samples. In chemical sunscreens, Avobenzone is a very good UV filter but it is the one that absorbs in the skin too.
Bad for the Environment:
Some of the ingredients found in chemical sunscreen are not considered safe for the environment either. For example, Oxybenzone is not safe for ocean and reef life. However, more research needs to be done on this topic.
