GABA
Bioactive Ingredients
GABA, which stands for gamma-aminobutyric acid, is a naturally occurring amino acid and neurotransmitter in the human body. While primarily known for its role in regulating brain activity and promoting relaxation, GABA has also gained attention in the skincare industry for its potential benefits when used as a skincare ingredient.
Relaxing and Anti-Aging Effects
In skincare, GABA is believed to have relaxing effects on facial muscles, similar to how it functions in the brain. When applied topically, GABA is thought to help reduce the appearance of fine lines and wrinkles by temporarily relaxing facial muscles, leading to a smoother and more youthful appearance. However, the extent of its effectiveness in this regard is a topic of ongoing research and debate.
Antioxidant Properties
GABA is known to have antioxidant activity, helping to neutralize free radicals that can cause oxidative stress and damage to the skin cells. As an antioxidant, GABA can contribute to protecting the skin from environmental aggressors and premature aging.
Anti-Inflammatory and Soothing
GABA may have anti-inflammatory properties, making it beneficial for calming and soothing sensitive or irritated skin. It can help reduce redness and inflammation caused by various environmental factors and skin conditions.
Skin Barrier Support
GABA is believed to assist in supporting the skin's natural barrier function, which is crucial for maintaining optimal hydration and protecting against external stressors.
Enhancing Skin Firmness
Some studies suggest that GABA may enhance skin firmness by stimulating the production of collagen and elastin, proteins responsible for maintaining the skin's structure and elasticity.
