Sun Safety in San Diego: Dermatologists Share Essential Skincare Tips

Sunshine in San Diego is often seen as more than a weather phenomenon; it is treated almost like a sacred ritual.

The sun captivates residents as they chase its warmth, occasionally feeling deprived when June gloom clouds the coast.

However, as a longevity doctor advocating for healthy living, I’ve come to realize that extending this adoration poses skin risks, including wrinkles, sunburns, and the potential for skin cancer.

Fortunately, local dermatologists are leading the way in sharing secrets to keep skin safe and glowing, even with the sun’s relentless rays.

### The Critical Role of Sunscreen

Dermatologists unanimously agree that sunscreen is a must-have for every San Diegan.

Dr. Swati Kannan, a double board-certified dermatologist and assistant professor at UC San Diego Health, stresses the importance of broad-spectrum sunscreen.

She recommends using SPF 30 or higher each morning, applied at least 30 minutes before sun exposure.

A nickel-sized amount is ideal for the face and neck, and reapplication every two hours is crucial for those spending extended time outdoors.

When it comes to sunscreen options, mineral formulations—featuring zinc oxide or titanium dioxide—are preferred.

These sunscreens not only provide superior protection but are also reef-safe, which is particularly advantageous for people who love ocean activities.

Dr. Saami Khalifian, another double board-certified dermatologist, favors these formulas for sensitive or post-procedure skin, reminding us that the best sunscreen is one we’ll use routinely.

It’s also important to note that SPF in cosmetics, such as foundation, generally does not offer sufficient defense against UV rays as most people don’t apply enough to achieve the labeled SPF protection.

For effective sun defense, dermatologists advise layering sunscreen under makeup.

### Enhancing Protection with Antioxidants

The conversation about skincare often turns to antioxidants.

Dr. Solomiya Grushchak, a double board-certified dermatologist and Mohs surgeon at La Jolla Cosmetic Laser Clinic, describes potent topical antioxidants like vitamin C and niacinamide as valuable allies.

They bolster the skin’s defenses against UV damage but should never replace sunscreen.

On an internal level, supplements like Polypodium leucotomos are hailed for their benefits, especially for individuals with heightened photosensitivity or previous skin cancer.

Dr. Kannan recommends taking 240 milligrams of this supplement twice daily for those frequently engaging in outdoor activities or vacationing in sunny regions, emphasizing that it acts as a useful supplement but not a replacement for topical sunscreen.

### The Power of UPF Clothing

In addition to lotions and serums, clothing serves as an effective barrier against sun exposure.

Dermatologists advocate for wearing garments with a high UPF (ultraviolet protection factor) rating for optimum defense.

According to Dr. Kannan, clothing offers dependable protection.

Unlike regular sunscreen, the efficacy of fabric doesn’t diminish over time, making UPF wear her top choice for outdoor sports and beach visits.

Dr. Grushchak echoes this sentiment, declaring UPF clothing to be one of the most efficient and low-maintenance means of minimizing UV exposure.

Another simple yet essential item is sunglasses with UV-blocking lenses, which protect the eyes from damage and prevent squinting-induced wrinkles around the eyes.

### Innovative UV-Blocking Laundry Detergents

A surprising yet ingenious addition to sun protection is UV-blocking laundry detergent.

Dr. Kannan endorses UPF-boosting additives, explaining how these products can enhance clothing’s sun defense significantly over around 20 washes.

This offers an affordable means to improve everyday garments’ sun protection.

### Timing and Consistency: Key to UV Protection

Being mindful of when to enjoy the outdoors is equally important in a sun safety plan.

Khalifian cautions that UV rays peak between 10 a.m. and 4 p.m., suggesting that outdoor activities be scheduled for early mornings or late afternoons.

He explains that fine lines and skin pigmentation issues arise more from UV exposure than just aging alone.

Don’t be led astray by San Diego’s frequent marine layer hiding the sun; cloudy skies do not equate to UV safety.

Many sunburns occur during overcast conditions when UV exposure remains high.

Dr. Grushchak advises treating cloudy days just like sunny ones, urging people to set reminders for applying sunscreen regularly every two hours.

### Putting the San Diego Sun-Proof Protocol into Practice

So, how can you implement this dermatologist-approved sunproofing routine into your life?

Start your morning by applying an antioxidant serum containing vitamin C and niacinamide, followed promptly by a broad-spectrum SPF 50 mineral sunscreen, regardless of weather.

Before heading outside, consider taking UV-protective supplements like Polypodium leucotomos, add a wide-brim hat, wear UPF clothing, and don polarized sunglasses, along with applying mineral sunscreen generously.

During midday hours, don’t forget to reapply sunscreen frequently, especially if swimming or sweating; keep a travel-sized product handy.

While in the car, be sure to use a sunscreen stick on any exposed skin, as UVA rays can penetrate windows.

Keep enhancing your sun defense in the laundry with UV-protective detergent for swimwear and everyday garments.

Lastly, after sun exposure, take the time to hydrate and moisturize your skin, skipping active ingredients if your skin is irritated or sunburned.

Living in San Diego means embracing the sun responsibly, and with these straightforward habits and useful products, protecting your skin becomes an effortless part of your daily routine.

### Insights from Dermatologists on Skincare

Curious about how dermatologists take care of their skin in sunny San Diego?

Their regimens are refreshingly straightforward and consistently adhered to.

Grushchak starts her day with a vitamin C serum underneath broad-spectrum SPF 30, often opting for tinted mineral formulas for added protection.

She keeps a sunscreen stick at hand while driving for quick reapplications on hands and arms, and she avoids peak UV hours as much as possible.

When outdoors, she opts for a hat and UPF jacket for added protection.

Khalifian’s regimen is minimalist yet effective: vitamin C serum, tinted mineral sunscreen, a wide-brimmed hat, and water-resistant SPF 50 lotion for his body.

He chooses lotions over sprays or powders for precision and employs UPF clothing on long outdoor excursions.

For melasma management, he also incorporates Sciton laser treatments into his skincare routine.

Kannan follows a dual approach, applying two layers of sunscreen (regular followed by tinted) during the morning while wearing sun-smart clothing.

Her nighttime routine includes a thorough double cleanse to remove all traces of sunscreen, coupled with tretinoin and pigment-fading serums to aid skin repair.
