'Natural' ek marketing descriptor hai, na ki properly defined cosmetic ingredient. Yeh basically plant, mineral ya animal sources se aane wala matlab deta hai, synthetic processes se nahi. Iska koi fixed regulatory standard nahi hai zyada tar regions mein aur inherent benefits ka guarantee nahi deta. Sab natural ingredients zaruri nahi hote safe ya effective - yeh depend karta hai ingredient type par aur kaise use kiya ja raha hai skincare routine mein.
