1. Gentle cleanser
Most commercially made soaps contain harsh surfactants that can strip your skin of natural moisture and oils, leaving it feeling dry and tight. To maintain your skin’s natural moisture, it’s best to use products that don’t remove the natural fats in the skin barrier. Goat milk soap boasts high amounts of fats, particularly caprylic acid, allowing for gentle removal of dirt and debris without removing the skin’s natural fatty acids.
2. Rich in nutrients
Goat milk is rich in fatty acids and cholesterol, which make up a large portion of the skin membrane.  A lack of these components in your skin can lead to dryness and irritation.  Furthermore, the milk is a good source of vitamin A, a fat-soluble vitamin shown to have anti-aging properties.  Finally, it’s a good source of selenium, a mineral shown to support a healthy skin membrane. It may even improve psoriasis symptoms like dry skin.  However, nutrient levels in goat milk soap largely depend on the amount of milk added during production, which is usually proprietary information. Moreover, it’s difficult to know how effective these nutrients are due to a lack of research.
3. Natural exfoliant
Goat milk soap contains compounds that may exfoliate your skin.  Alpha-hydroxy acids (AHAs) are used to treat a variety of skin conditions, such as scars, age spots, and hyperpigmentation, due to their natural ability to exfoliate.  Lactic acid, a naturally occurring AHA found in goat milk soap, has been shown to gently remove the top layer of dead skin cells, allowing for a more youthful complexion.  What’s more, lactic acid is known as one of the gentlest AHAs, making it a suitable option for those with sensitive skin.  However, the amount of AHAs in goat milk soap remains unknown, making it difficult to know how effective it is at exfoliating the skin. Therefore, more research is needed.
