Yeah, I understand your thinking, big pharmacy can influence many things. But in this specific situation, it is the opposite. Many “green” companies such as the EWG have created myths surrounding sunscreen filters and their “deadly” consequences. It is all horseshit, completely fabricated to promote their alternative products. Sunscreen filters are some of the most rigorously tested (by the government and independently) ingredients that can be applied topically to the skin, and still, every single sunscreen on market must pass massive efficacy testing before it can be sold. I would check who was writing these articles and are qualified to give any sort of professional advice about your skin (dermatologist, esthetician, etc). Because if it is not at least written in collaboration with a qualified professional I would disregard it.
Many things contribute to us needing more sun protection now, as the world split into continents and not everyone required the same amount of natural sun protection our skin got paler and more successively to the suns rays. Also, the ozone layer has decreased dramatically due to climate change causing an increase in the number and strength of the UV rays that reach the ears surface.
Most people are vitamin D deficient, but this is because of the previous factors I originally mentioned not because of the invention of sunscreen filters. The suns damage has also been studied more in the last 100 years, so the pros and cons have been weighed and as vitamin d can be completely synthesised there is no requirement for excessive sun exposure.
Also, our ancestors did not have the same long lifespan as we do now, so it is likely that the sun did not have the time to actually show it damage or they did develop skin cancers that went unnoticed (obviously their was no medicine to diagnose) causing them to die. The environment is completely different now, so we’re unable to draw effective comparisons between them.
Also coconut oil, and oil by nature, is not hydrating despite what they are often marketed at. What oils do to the skin it really in any water and hydration that is already there (after showering I moisturise then use an oil over my body to lock it in). But because oils are only occlusive they cannot add any water to the skin (they also have no water content). Body oils can be great, on top of moisturisers and then after 15 mins underneath sunscreen.
