Infant sunblock

Looking for infant sunblock can be quite controversial in that a child under 6 months really shouldn't have it's skin exposed to the sun directly.

In general, all individuals or organisations, whether qualified doctors, pediatricians, dermatologists, cancer research companies, sunscreen manufacturers, or Government official bodies, will say that no child under 6 months of age should be exposed to the sun either directly or indirectly. 

However, they do also all say that if there is no choice available, then there are some infant sunblock options to consider as the best choice for the child's protection.

Infant sunblock- Common questions asked 

  • My daughter is three months old and as we spend a lot of time outdoors I would like to know what type of sunblock I can use on her?
  • Is there any infant sunblock suitable for babies younger than six months? Most sunscreens or sunblocks say not for younger than 6 months on their labels so I am not sure what to use?
  • We keep our 4 month old baby under an umbrella or in the shade when we are outdoors, but her cheeks still seem to get a little rosy. Is there a sunblock for infants to recommend?
  • The doctor said we must keep our baby of 5 months out of the sun altogether between 10am and 4pm but we are just not able to do this every day. Can you recommend a sunblock for babies under 6 months?

There are actually many sunblocks on the market that claim to be for 'babies' or infants' but in reality are compelled to put 'not for use on children under the age of 6 months' on their labels.

Recommendations for Infant Sunblocks

  • use UPF clothing that covers up their body, arms and legs, plus a hat
  • use a full baby UPF swimsuit if at the beach or pool and wanting to get into the water with them
  • use an umbrella or solid shade of some sorts to protect them from any reflective surfaces
  • apply infant sunblock to any exposed skin areas, especially the typically forgotten ones like the back of the neck, the ears, the tops of the feet

Various experts now agree that, for babies under six months old, it's okay to put sunblock on ONLY if in small amounts on small areas of the child's body, as the benefits will outweigh the risks.

Dr Robert Steele explains the reasons for this:
"Infants and children have what is called a high body surface to volume ratio.

What this means is that proportionately babies have more skin for the size of body as compared to an adult.

Sunscreens are made of chemicals.

On the older child or adult, the chemical exposure is relatively minimal because the body surface ratio is smaller than a baby.

Therefore, babies get a higher 'dose' of sunscreen than do those that are older. While this exposure would most likely not cause any problems, the likelihood of an adverse reaction is much greater."

Also, babies do not necessarily have a more sensitive skin. Instead, they have a thinner skin.

This means that they absorb more of the chemicals in the sunscreen and because their organs aren't capable of processing the same amount of chemicals as an adult. This means it can be a whole lot more damaging to them. 

Most people don't realize how much we absorb of everything that we put on our skin.

So the big message here is not to cover your child from head to toe with an infant sunblock, but to supplement where required on small parts of exposed skin.

Best Choice: Zinc oxide infant sunblock   

sunscreen active ingredients

New research from the skin cancer foundation is proving that it isn't necessarily the amount of time a person spends outside that increases their risk of skin cancer but instead it's the age that they started being in the sun.

The younger the age the higher the risk of skin cancer.

It's better to keep your baby out of the sun altogether if you can.

But when that's not possible, I recommend choosing a "physical" or "chemical-free" infant sunblock made with zinc oxide ONLY and free from any toxic chemical ingredients.

Unlike chemical sunscreens, which may cause irritation or allergic reactions because the skin absorbs the active ingredients, zinc oxide sits on top of the skin, forming a barrier against the sun's rays.

Another important factor is that sunscreens with zinc oxide start protecting as soon as you put them on.

The following sunblocks may claim to be "specially formulated for babies" but I have an issue with some of the ingredients:

BANANA BOAT Infant & Newborn: 

The following ingredients are contained in this infant sunblock:

  • Homosalate
    Research indicates it is a hormone disruptor, forms toxic metabolites, and can enhance the penetration of some toxic herbicides.
  • Octinoxate (Octyl methoxycinnamate)
    Estrogenic effects were noted in laboratory animals at concentrations close to those experienced by sunscreen users and were also shown in test tube experiments.
    A study published in 2011 explored the effects of pre- and post-natal exposure to high doses of octyl methoxycinnamate in rats and showed, for example, that the testes weight and testoserone levels were significantly reduced in male rats
  • Octisalate
    This typically undergoes some degradation when exposed to sunlight and although the safety record seems to be fairly good, it has been linked to contact dermititus.
  • PEG
    A carcinogen containing dioxane, which is one of the most potent toxins known to man.
  • Olefin/Isopropyl Maleate/MA Copolymer
    All polymers are essentially plastics
  • C30-38
    another polymer
  • Phenoxyethanol 
    According to a warning by the FDA of 2008 "Phenoxyethanol is a preservative that is primarily used in cosmetics and medications. It also can depress the central nervous system and may cause vomiting and diarrhea, which can lead to dehydration in infants".
  • Methoylparaben, Butylparaben, Ethylparaben, Propylparaben, Isobutylparaben
    These 'endocrine disruptors' are gender-bending chemicals which mimic estrogen, upset hormonal balance, and can cause various reproductive cancers in both men and women.

Avalon Infant & newborn Natural Mineral Sunscreen:

  • PEG 100 Stearate (Polyethylene Glycol 100 Stearate)
    This is a carcinogen containing dioxane, which is one of the most potent toxins known to man.
  • Phenoxyethanol (Natural Preservative)
    According to a warning by the FDA of 2008 "Phenoxyethanol is a preservative that is primarily used in cosmetics and medications. It also can depress the central nervous system and may cause vomiting and diarrhea, which can lead to dehydration in infants".

Aubrey Organics Green Tea Sunblock for children

  • Padimate O (PABA Ester)
    A derivative of the once-popular PABA sunscreen ingredient, research shows this chemical releases free radicals, damages DNA, has estrogenic activity, and causes allergic reactions in some people.
    Also causes genetic mutation when exposed to sunlight.
