Sunscreen Ingredients 101: What to Look for In Sensitive Skin Formulas

Why Choosing the Right Sunscreen Ingredients Matters

Using the wrong sunscreen ingredients can harm all skin types, not just sensitive ones. Harsh chemicals and unsuited formulations can lead to:

Clogged pores and breakouts for oily skin.
Increased dryness and flakiness in dry skin.
Irritation and redness in sensitive or reactive skin.
A weakened skin barrier can lead to high chances of UV damage for all skin types.

Selecting the right sun protection ingredients ensures optimal UV defense while addressing specific skin needs. This tailored approach protects skin health and maintains its natural balance.

Common Sunscreen Ingredients Explained

Understanding sunscreen ingredients is the first step to making an informed decision. Here are most of the common types:

Zinc oxide: It is a mineral blocker that provides broad-spectrum UV protection while being gentle on sensitive skin.
Titanium oxide acts like a physical blocker, reflecting UV rays and preventing them from penetrating the skin.
Avobenzone: It is one of the chemical sunscreen ingredients that absorbs the UV rays and breaks them down to heat.
Octisalate and Octocrylene: They stabilize other sun protection ingredients and enhance the water resistance of the sunscreen.

Physical vs Chemical Sunscreens: Which is Better for Sensitive Skin?

Physical and chemical sunscreen names can be confusing because both are skin products, yet "physical " feels like a piece of clothing or other physical barrier. Their names come from their action of protecting the skin from the sun. Here is a little more about them:

Physical sunscreens: These contain zinc oxide and titanium dioxide, which sit on the skin's surface and reflect UV rays. They are ideal for sensitive skin.
Chemical sunscreens protect by absorbing UV rays and converting them into heat. However, due to the chemical reaction, they may cause skin irritation in people with sensitive skin.
