Deconstruct — Gel Sunscreen for Oily Skin
What Does Sunscreen Actually Do?
According to the World Health Organisation (WHO) has warned us against how UV radiation is a well known human carcinogen and have highlighted the key role that sunscreens play in reducing the risk of skin cancer.
There are two types of UV radiation we face daily
UVB- immediate sunburn, tanning
UVA - long term sun damage, pigmentation, tanning and premature ageing
Sunscreens act as a protective barrier over the skin and protects your skin by two mechanisms:
They either absorb (Chemical sunscreens) or reflect and scatter (Physical or mineral sunscreens) harmful UV radiation.
Broad-Spectrum Protection Explained
UV radiation has both short term and long term health effects, as noted by WHO
-
Skin cancer
-
mayuriPremature ageing
-
Pigmentation and dark spots
-
Tanning
-
Excessive UV exposure can even cause DNA damage
Here’s why modern sunscreen formulation that offers protection against both UVA+ UVB.
-
Sun Protection Factor (SPF) measures how much protection your skin gets primarily against UVB rays. But not UVA.
-
UVA rays penetrate deeper into the lower layers of your skin than UVB, reaching lower dermal layers of the skin and causing long term damage, pigmentation , tanning and premature ageing and even damage DNA in the long term.
This is why you need a broad spectrum sunscreen, which offers both UVB+UVA protection, giving you a well-rounded protection against UV.
The American Academy of Dermatology (AAD) recommends daily application of a broad spectrum sunscreen with an SPF of 30 or higher to all areas of the body exposed to the sun for effective protection against the harmful effects of UV radiation.
Is Sunscreen Really Necessary Every Day?
Dermatologist Consensus
All dermatologists and skincare experts recommend daily use of a sunscreen with SPF 30 or higher as a non-negotiable for anyone spending time outdoors, under direct sunlight or even indoors and cloudy days, as UVA rays penetrate deeper and even through glass windows and present almost all year round, even if it’s not sunny
According to the Journal of the American Academy of Dermatology, daily use of sunscreen is crucial in preventing photoageing, which is premature ageing caused by the long-term cumulative damage from UV exposure.
What Happens If You Skip Sunscreen?

Do You Need Sunscreen Indoors or on Cloudy Days?

Indoor Exposure (Windows, Screens)
