How Natural Ingredients Tighten Skin: The Science
Skin loses firmness when collagen and elastin break down due to:
- Aging (collagen drops 1-2% yearly after 30).
- Rapid weight loss (link to weight loss surgery guide).
- Sun damage and dehydration.
These ingredients work by:
🔬 Stimulating collagen (e.g., vitamin C).
💧 Deeply hydrating (e.g., hyaluronic acid).
🛡️ Protecting from further damage (e.g., antioxidants).
