We all use sunscreen to protect ourselves from the sun's harmful rays, but do we notice whether it is 'Physical' or 'Chemical' when buying it?

These two terms are frequently heard in the world of skincare, but their mechanisms are entirely different. In today’s blog, we will explain the differences between these two types of sunscreen in simple terms and help you decide which one you should choose for your skin.

1. Physical Sunscreen

Often called 'Mineral Sunscreen', its primary ingredients are Zinc Oxide or Titanium Dioxide.

• How it works: It creates a protective shield on top of your skin. When sun rays hit your skin, it reflects them away like a mirror.

• Pros:

• Starts working immediately upon application (no waiting time).

• Best for those with highly sensitive skin.

• Also safe for use on children's skin.

• Cons:

• Can sometimes leave a slight white cast on the skin.

• It can feel a bit heavy and may wash off quickly with sweat.

2. Chemical Sunscreen

This contains ingredients (such as Avobenzone or Oxybenzone) that absorb the sun's harmful UV rays.

• How it works: It acts like a sponge. It doesn't let the sun's rays penetrate deep into the skin; instead, it converts them into heat and releases them from the skin.

• Pros:

• Blends easily into the skin without leaving a white cast.

• Very easy to use as a primer under makeup.

• Generally thinner in consistency and often water-resistant.

• Cons:

• It takes at least 20 minutes to start working after application.

• May cause some irritation for those with very sensitive skin.

Expert Insight: According to the American Academy of Dermatology, physical sunscreens are highly recommended for people with sensitive skin because they are less likely to cause irritation.
