Best sun cream and advice for children developing new moles

[MumToBe1980]

I have noticed that my 2 children (age 6 and 10) seem to be developing quite a lot of moles particularly on their face and neck despite me applying sunscreen. We don't spend lots of time in the sun, wear hats and I always apply suncream. Despite this they have gained at least 6 new moles each this summer so far. Dad is very 'moley" so possibly genetic.
Im pretty wortied about this as my mum has stage 4 melanoma and is very poorly now so want to try to reduce their chances of getting melanoma in the future much as possible whilst I can.
Can anyone recommend any sun creams for mole prone skins please? Or any other advice appreciated.

You are right, it’s genetic.

I use Aldi factor 50. Or Tesco. Fair with red hair. Wear normal swimwear on the beach. Never burn.We spend a lot of time outside.

Moles are rarely apparent at birth. They appear later.

Good hats. Rash t shirts for swimming or any other outdoor activity. Good quality sunscreen lavishly used.

Growing up, we had to stay indoors between 11 and 3.
