How do I make the player invisible in a way that it won't glitch if other parts are added to player?

A youtube video I checked out on how to turn the player transparent said that I should loop through the character like so:

for i,v in pairs(character:GetChildren()) do
	if v:IsA("Part") or v:IsA("MeshPart") then
		v.Transparency = 1
	end
end

And I thought to myself, is this a secure way doing it? Because if any other parts are added to the player then won't it turn that invisible as well? I that something I should even be concerned about and is this even a good way to go about it?
