Glycerin soap offers several benefits, primarily due to its moisturizing and gentle properties. It attracts and retains moisture, making it ideal for dry and sensitive skin. It also helps maintain the skin's natural moisture barrier, prevents over-drying, and can be gentle enough for those with sensitive skin or conditions like eczema and psoriasis. 
 
Here's a more detailed look at the benefits:
Gentle on Sensitive Skin:
Glycerin soap is less likely to cause irritation than traditional soaps, making it suitable for sensitive skin, eczema, psoriasis, and allergies, according to some skin care sources. 
Maintains Skin's Moisture Barrier:
Unlike many soaps that strip the skin of its natural oils, glycerin soap helps preserve the skin's protective barrier, promoting overall skin health. 
Versatile Use:
It can be used on the face, hands, and body, and even for shaving and makeup removal, say some beauty blogs. 
May Help with Certain Skin Conditions:
Some people find that glycerin soap helps to soothe and improve conditions like acne, dermatitis, and rosacea. 
Natural and Biodegradable:
Many glycerin soaps are made with natural ingredients and are biodegradable, making them an environmentally friendly option. 
Deep Hydration:
Glycerin is a humectant, meaning it draws moisture from the air and into the skin, keeping it hydrated without feeling greasy.
