What is the primary function of Natural Moisturizing Factors in the skin?

Explanation:
Natural Moisturizing Factors are a group of water-attracting compounds (such as amino acids, lactic acid, urea, minerals) located in the outer skin layer. Their main job is to pull in and hold onto water within the stratum corneum, keeping the epidermis hydrated, flexible, and able to maintain its barrier function. This is why the primary function is to lock in moisture within the epidermis. They don’t provide color, don’t specifically protect against UV, and aren’t directly responsible for keratinization, which relates to the formation and maturation of skin cells rather than moisture retention.
