Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Containers of Study Sunscreen and Control Sunscreen will be in unmarked tubs i.e. ingredients not marked.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
As this is an intra-patient trial with each participant serving as treatment arm and placebo, this will be simple randomisation by coin-toss
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
