Sunscreen – Here’s What You Need to Know!

Sunscreen is important all year round. But it’s incredibly important now when summer in Boston has reached its peak. Your skin will be glow only if you will protect it and take care of it – not just with a few facials but also with a regular daily skincare routine that includes SPF!

Have you ever said: “It’s cloudy outside, I don’t need sunscreen.” or ” But I only tan once in a while and I haven’t burned in years.”? Then you definitely need to read this blog post.

BUT FIRST – some facts!

90% of visible signs of aging are related to UV exposure

It’s really that simple! Not forgetting about sunscreen and using it daily helps to reduce the signs of aging by 90%!

UVA rays are responsible for premature aging.

UVB rays are responsible for redness and burning.

When choosing your SPF, Sun Protection Factor,
remember – there are 3 types of sun rays, but 2 types are responsible for our skin.

Even a short duration of sun exposure to unprotected skin is enough to cause burning and sun damage.

After 15 minutes unprotected skin starts developing sun damage. Damage to skin cells happens over a lifetime. It is cumulative.

Physical/Mineral vs. Chemical SPF


  • Physical/Mineral SPF has zinc oxide or titanium dioxide as active ingredients. It’s physically blocking sun rays.
  • Chemical SPF has different compounds like Octinoxate and Octisalate. Chemical sunscreen transforms UV rays into heat energy.


  • Mineral SPF can typically be a bit thicker, milky white formula that needs to be thoroughly and generously rubbed in. 
  • Chemical sunscreen tends to be a thinner, clearer formula that is easily absorbed into the skin.

Skin type:

  • Mineral sunscreen is recommended for sensitive, acne-prone and rosacea skin because it’ll less likely to clog pores.
  • Ingredients in chemical SPF ensure broad-spectrum protection results but there’s a higher likelihood of irritation for sensitive skin.


  • Mineral SPF protects your skin instantly. It also remains effective for longer in direct sunlight.
  • Chemical sunscreen absorbs more easily, but you need around 20 minutes for it to become fully effective and needs to be applied more often.

All that being said, mineral SPF loses effectivity when the body gets wet or sweaty. Chemical sunscreen, on the other hand, ensures better protection from UV rays. So, when the summer in Boston is especially high, you definitely want something that stays on your skin even when you go for a swim or just sweat too much!
