An Introduction to Natural Baby Sunscreen

Start Using Natural Sunscreens and Other Natural Sunblock Alternatives

 Baby with blue sunhat. Being outdoors with your baby is essential but protecting your baby from harmful UV rays can sometimes be a difficult task. Many of us lather ourselves and our babies with chemical filled sunscreens which may be more harmful to your health than the sun. Learn how you can protect your baby from the sun with natural sunscreens. 


Chemicals in conventional sunscreen

Many of the ingredients used in conventional sunscreens pose their own problems, making the decision whether to use sunscreen or not a difficult one. The list of harmful possibilities is very long (see the Environmental Working Group’s Active Ingredient List for a full breakdown), but consider these potentially harmful ingredients:

  • DMDM Hydantoin:This is a preservative used in many baby care products, yet it is a known human immune system toxicant and a suspected skin irritant.[1]
  • Octinoxate: This chemical suffers from one of the most common problems with sunscreen ingredients—it is likely to disrupt natural hormone levels, even in small babies. This chemical also has several names, including octyl methoxycinnamate.[2]
  • Oxybenzone:Known also as benzophenone-3, oxybenzone is a chemical sunscreen that has come under scrutiny because of concerns about skin irritation and hormone disruption.[3]
  • PABA: This chemical goes by many names, including Padimate O and Octyl Dimethyl PABA. The main danger here is that it releases free radicals which can damage DNA. It has also been linked to hormone disruption and can cause allergic reactions.[4]
  • Triethanolamine (TEA):Used as a fragrant ingredient, a pH adjuster, and an emulsifier, TEA is known to be an immune system toxicant, a skin toxicant, and a respiratory toxicant. There is also evidence that it might play a role in organ system damage.[5]


Potential sunblock alternatives

So, what’s a mom or dad to do about the sun? One highly-safe option is to turn to sunscreen clothing—pieces of clothing from baby’s existing wardrobe that provides a good level of Sun Protection Factor (SPF). You’ll need to consider the clothing’s effectiveness, however, in fending off the sun. The Ultraviolet Protection Factor (UPF) varies from one fabric to another—one of the most protective levels is scored at 50 UPF. In general, however, you can follow some simple rules for what fabrics work best for UPF clothing:

  • Silk, wool, and polyester provide the best protection over things like cotton or linen.
  • The thicker the clothing and the tighter the weave the better a fabric will be at blocking UV rays, but keep the clothing loose fitting to allow for optimal circulation and better UV absorption.
  • Darker is also optimal since dark colors can absorb more UV penetration, giving dark clothing a higher UPF than light clothing.
  • Dry clothing has a higher UPF than wet clothing, so keep out of the water if possible.
  • Don’t be fooled by labels that tout a UPF rating—these are likely made of synthetic fibers (always try and choose natural fabrics) and treated with UV absorbers which may not be healthy for baby (or you).


Natural baby sunscreens

If you’re feeling particularly concerned about the sun, however, you could consider commercially-available sunscreen brands that eschew the use of the scary ingredients outlined above (but only if your baby is 6 months or older—sunscreens should not be used on younger infants). When shopping for your natural baby sunblock, look for mineral sunscreen ingredients like zinc oxide or titanium dioxide. As long as these are applied in cream or liquid form (and not spray or powder form that can be inhaled),[6] they are quite effective and safe. Even nanoparticle sized zinc oxide and titanium dioxide appear to be quite safe, according to the Environmental Working Group’s study of the material.[7] Here are some natural baby sunscreen brands you can seek out at your local health food store or online:

You want gentle products for your baby, and hopefully products that don’t come at the cost of another animal’s wellbeing. So look for the Certified Vegan or Leaping Bunny logos to assure that your chosen products don’t come at the pain of other creatures.
