Health Benefits
1. Skin Health
Aloe vera is perhaps best known for its skincare benefits. It is commonly used to soothe burns, cuts, and other skin irritations. The gel has anti-inflammatory properties that help reduce redness and swelling. It also promotes the healing of wounds and can improve skin hydration.
