Physical vs Chemical Sunscreen
What is Physical Sunscreen?
Physical Sunscreen (sometimes called Mineral Sunscreen) forms a protective physical barrier of inert minerals over the skin, is not absorbed by the skin, and is less likely to cause skin irritations.
- Does not enter the skin
- Works immediately
- Gentle on skin
- Less likely to clog pores
- Stable in sunlight
- Longer shelf life
- Safe for babies and pregnant moms
- Non-nano versions are reef-safe
- Zinc Oxide is most complete broad spectrum
- Will likely leave white tint on skin
- Thicker to apply
- More difficult to remove after use
- Titanium Dioxide doesn't protect entire UVA spectrum
- More expensive
What is Chemical Sunscreen?
Chemical Sunscreen (sometimes called Synthetic Sunscreen) uses petroleum-based synthetic compounds to absorb rays. It absorbs into skin. Note: Strictly speaking, all sunscreens contain chemicals (even water is a chemical). We use “Chemical” to differentiate non-mineral sunscreens from those using petrochemicals.
- Lightweight application
- Less residue on skin
- Thinner and easier to spread
- Commonly found at all big stores
- Less expensive
- Increase risk of cancer
- More likely to irritate skin and eyes
- Generate free radicals in the skin when exposed to UV light
- Unstable and break down in sunlight
- Without avobenzone or oxybenzone, likely doesn’t protect from UVA rays
- Can disrupt hormones, including endocrine levels
- Because of the produced heat, can increase brown spots
- Protection begins about 20 minutes after application
- Clog pores and increase breakouts
- None are reef-safe
- Multiple chemicals required to provide both UVA and UVB protection and higher SPFs
