Spending time outside is a natural way to boost mood and overall longevity, but without proper protection, you can end up with sun spots. Sun spots are a form of hyperpigmentation and are among the most common signs of skin aging. Also referred to as age spots, liver spots, or solar lentigo, sun spots are characterized by discolored and darkened patches on the skin, and are usually a result of sun damage.

Harmful Ingredients in Sunscreens: What You Need to Know
The two types of sunscreens are based on their active ingredients, and include chemical sunscreens and physical (or mineral) sunscreens. Chemical sunscreens work by absorbing high energy UV rays and emitting them at low energy levels as heat. Mineral sunscreens work by forming a physical barrier that blocks UV rays from penetrating skin cells.

Key Takeaways:
- Sunscreen, along with other key products like peptide moisturizer and peptide eye cream, is an essential part of any skin care routine as it protects the skin from harmful UV rays from the sun.
- If sunscreen is worn at the recommended frequency, it will be one of the most common products that your skin is exposed to, therefore it’s especially important to ensure your daily sunscreen doesn’t contain harmful ingredients.
- There are two types of sunscreen, chemical and physical. Physical, or mineral sunscreens are much less likely to cause adverse reactions such as contact dermatitis when applied.
- There are 12 ingredients the FDA has declared as unsafe or unsafe in high concentrations when used in sunscreen, most of which are contained in chemical sunscreens.
- Other additives such as fragrances are often added to sunscreen and can potentially cause allergic reactions.

How do you view aging and longevity?
“Aging is a mixture of increasing wisdom as well as decreasing vitality. I think as a doctor you have a really good view of the natural aging process and how hard it is. Because of that, I have a lot of motivation to stay as physically active and healthy as I can. To enjoy my time and not have so much discomfort as I age.”
