No, not all men use skin care products, but the number of men using skin care products is increasing. Traditionally, skin care has been marketed towards women, but in recent years, there has been a growing trend of men taking more interest in their skin health and using skin care products.
Men's skin has unique needs and concerns, and there are now many products specifically formulated for men's skin, such as cleansers, moisturizers, and anti-aging products. Men's skin tends to be thicker, oilier, and more prone to acne than women's skin, and can also be more susceptible to damage from shaving.
Many men now incorporate skin care into their daily routine, either for practical reasons such as shaving, or for aesthetic reasons such as improving the appearance of fine lines and wrinkles. However, the use of skin care products is a personal choice, and not all men may choose to use them.
