Are chemical sunscreens sustainable? Mineral sunscreens, the best alternative for our planet and body.


Hey there! If you landed on this post, it’s probably because you love going out and enjoying the sun ( we see you! ), or maybe because you are a planet-lover and want to know exactly what goes into your skin when using cosmetics.  If you happen to be here out of curiosity, welcome too. Stay a little longer to learn the effects of chemical sunscreens on our skin and the planet.  Read on! 

Is your sunscreen bad for the oceans?

Great question! Well, the truth is that it depends. Are you opting for mineral or chemical sunscreens? If you are using the former, you are definitely protecting our oceans. If you happen to be using a chemical lotion, here  are a few reasons why you should switch teams:

  • Globally, over 14,000 tons of toxic sunscreen enter the ocean each year.
  • Chemical sunscreen accumulates in the tissues of corals, which can induce bleaching, damage their DNA or even kill them. 
  • Chemical sunscreens decrease fertility in fish. 
  • Dolphins are affected too, as sunscreen can accumulate in their tissues and be transferred to baby dolphins.


Is Chemical Sunscreen Safe? 

Well, some of the ingredients in chemical sunscreens can be considered controversial, that’s why we always recommend sticking to mineral sunscreens. 

Chemical sunscreens and mineral sunscreens, what’s the difference?

Mineral sunscreens: 

  • Reflecting light. Zinc oxide and titanium dioxide, are the small particles in charge of preventing UV rays from penetrating the skin.
  • Protect our skin immediately after application
  • Great for sensitive skin. 
  • Protect our oceans and marine life. 

Chemical sunscreens 

  • Absorb into the skin after 20-30 minutes of application. 
  • Have a synthetic formulation.
  • Contain chemical filters such as avobenzone, oxybenzone, ecamsule, and octocrylene, which could potentially cause irritation. 
  • Damage marine life and our oceans.

 What’s the best mineral sunscreen?

The best mineral sunscreens for both face and body should have a clean formulation to protect our skin from UV rays and keep our oceans nice and clean as well! Using mineral sunscreens doesn’t mean letting your guard down! You should always try to use broad-spectrum SPF 50 both for your face and body! And now,  for the million-dollar question: Does sunscreen prevent tanning? No,  it doesn’t, tan is your skin’s response to ultraviolet rays, so when the skin is exposed to UV radiation, it produces melanin to protect itself from damage. The only thing sunscreen prevents is wrinkles and annoying sunburn among other issues!! 

If you are looking for a face and body sunscreen we’ve got you covered:
