Are you slathering on the SPF correctly? Both UVA (think: aging) and UVB (think: burning) rays can cause redness and cellular damage (even tan).
Any sunscreen—lotions, creams, sprays—offering “broad spectrum” or has the PA label (or has both!), is the right product for you.
Types of Sunscreen 🧴☀️
Type 1 👉Mineral sunscreens typically contain ingredients, like titanium dioxide and zinc oxide, and sit on top of the skin, blocking UVA and UVB rays.
Type 2 👉Chemical-based sunscreens typically contain carbon-based ingredients, like oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate. These ingredients turn the UV rays into non damaging heat. Their formulations are thinner in texture and spread on easily.
🙌All about SPF and PA🙌
This is an important distinction because SPF (sun protection factor) measures only UVB protection while the PA rating only measures UVA protection.
PA+ = Some UVA protection
PA++ = Moderate UVA protection
PA+++ = High UVA protection
PA++++ = Extremely High UVA protection
Higher SPFs⬆️ don’t mean you can stay out in the sun longer, they are simply meant to increase your protection when you do have to be outside.
For example, SPF 15 products block 93 per cent of UVB rays, compared to 97 per cent for products SPF 30 and higher.
☀️How much to Apply?☀️
Experts suggest putting one ounce of sunscreen on your entire body, or enough to fill one shot glass.
