What if this simple ritual could hydrate your skin, ease joint aches, and even promote restful slumber—all after you hit 30, when life’s wear starts showing?

Ever noticed fine lines creeping in or mornings feeling stiffer? Let’s uncover six compelling reasons to make castor oil your bedtime ally. But first, why does your body feel the grind past 30?

The Subtle Strains of Aging After 30
Turning 30 often brings a shift—skin loses its glow, joints creak from desk hours or workouts, and sleep gets elusive.

You’ve likely tried creams or pain relievers, but they’re costly or temporary. What if a natural elixir, tucked in your cabinet, could ease these woes overnight? Castor oil, often overlooked, may deliver relief with a dab or drizzle. Ready to explore its magic? The first benefit soothes your skin’s nightly repair.
