Episode notes
Environmental Impact of Collagen Boom
- The collagen boom drives deforestation and displaces indigenous people in the Amazon rainforest.
- Collagen supplements have weak evidence, while retinoids effectively boost skin collagen production.
How Much Sunscreen to Apply
- Apply about a quarter teaspoon of sunscreen for your face and about a teaspoon for head, neck, limbs, front and back body parts.
- Use the right amount to achieve the SPF protection listed on the bottle for effective sun protection.
Mineral vs Chemical Sunscreens
- Mineral sunscreens reflect only a small fraction of UV rays; most UV is absorbed and turned into heat.
- Chemical sunscreens absorb UV and convert it to heat; both types provide effective protection.
