Physical Sunscreen VS Chemical Sunscreen

Why do we need sunscreen?

Sunscreen is the first defense against aging.

What are the differences between physical sunscreen and chemical sunscreen?

Chemical sunscreen Absorbs into skin and change the UV rays into heat (e.g. octinoxate, homosalate) Mostly protects against UVB only May disrupt hormonal balance in our body (human sex hormone and thyroid hormone) May cause allergic reaction Need to apply about 20 to 30 minutes before exposure to sun

Physical sunscreen Zinc oxide and titanium dioxide Sits on the skin surface to reflect all UV rays (UVA & B) No absorption into the skin Safe Possesses anti-inflammatory effect No need to wait before sun exposure

How to select an effective and safe sun-care product?

Look for physical sunscreen ingredients:

• Zinc oxide (micronized)
• Titanium dioxide

Avoid chemical sunscreen ingredients:

• Homosalate
• Octinoxate (Octylmethoxycinnamate)
• Octisalate
• Octocrylene
• Oxybenzone

Avoid harmful chemical preservatives such as parabens, methylisothiazolinone (allergen of the year).

Look for additional functional ingredients that can enhance the effect of sun protection if possible, such as raspberry seed oil.

Additional anti-inflammatory effects from ingredients like vitamin B3 or leontopodium apinum extract will be a bonus add-on to the sun-care product.
