I always see these two words used on products for skin and hair, yet despite looking for a solid answer I can’t seem to understand what the difference is or really what each does.
In: Chemistry
One difference could be in oils vs water. Most oils don’t mix with water, and “hydrating” means or heavily implies the addition of water or a gel that features water-like properties. Moisturizing could honestly be a word to mean anything. But for conditioners or most soaps, it’s gonna mean it leaves oil behind for positive benefit.
