SHORT DIVE: THE SUNSCREEN GUIDE NOBODY GAVE YOU (PART 2)

Chapters 4–8: How much to actually use, the vitamin D balance, what to do for your specific skin, the hormonal pigmentation connection, and the complete practical guide.

This is Part 2 of The Sunscreen Guide Nobody Gave You. If you haven’t read Part 1 yet, start there, it covers what UV radiation actually does to your skin, the myths costing you the most, and the current, honest picture on mineral versus chemical filters. This part is where it becomes a routine you can actually use.

Part 2 is about the things that matter just as much and get almost no attention: how much you’re actually applying, whether your protection routine is quietly making you vitamin D deficient, what to do if your skin doesn’t tolerate standard formulas well, and the hormonal layer of pigmentation that no amount of perfect SPF technique alone will fully solve.
