 🌍 External Factors That Affect Skin

Sun Exposure

Sunlight can feel amazing on your skin, right? A little warmth, a natural glow, and even a boost of vitamin D. But here’s the flip side—unprotected sun exposure is one of the most damaging things you can do to your skin UV rays break down collagen and cause dark spots. Sunscreen is non-negotiable.

The UV Breakdown


Sunlight contains ultraviolet (UV) rays—mainly UVA and UVB. Each plays a different role in damaging the skin:

  • UVA rays go deep into the dermis. These rays cause premature aging, fine lines, and wrinkles.
  • UVB rays affect the surface layer and are the main cause of sunburns and skin cancers.





Pollution

Airborne toxins can clog pores and accelerate aging. Cleanse well and use antioxidants.

Pollution: The Silent Skin Aggressor

You may not see it, but the air around you is full of tiny, invisible particles—and many of them are bad news for your skin. From car exhaust and cigarette smoke to industrial emissions and dust, these airborne pollutants are microscopic troublemakers. They settle on your skin and trigger a chain reaction: 


Climate and Environment

Humidity, cold, wind, dry air—all impact your skin. Adjust your routine accordingly. Ever notice how your skin feels different in the summer versus winter? That’s not just your imagination.

Hot and Humid Weather In tropical or summer climates, humidity levels rise, and so does oil production. This can lead to:

Greasy skin and clogged pores Increased acne breakouts More sweat, which mixes with dirt and bacteria

What to do: 

Use a lightweight, oil-free moisturizer Switch to a gel-based cleanser Blotting papers help manage shine without over-washing.
