Physical vs. Chemical Sunscreen: What Reef-Safe Sunscreen Should I Use at the Beach?

Sun protection is a vital part of any routine, regardless of the weather. However, now that the weather is getting warmer and we’re beginning to make plans for spring break, there’s another factor to consider when it comes to your sun protection selection: is your sunscreen reef-safe? Recent research suggests that certain chemical sunscreen agents, such as oxybenzone and octinoxate, are harmful to coral reefs. The ocean’s ecosystem is delicate, and while coral may only cover approximately 1% of the ocean’s floor, it is responsible for housing a multitude of fish, invertebrates and algae that are essential to all kinds of marine life. Read on to discover some of our favorite reef-safe sunscreen ingredients and formulas.

What are Oxybenzone and Octinoxate?

Oxybenzone and octinoxate are chemical sunscreen ingredients found in many sunscreens due to their ability to absorb UV rays and protect skin from sun damage. These ingredients are very effective at preventing skin cancer and burning, but have also been shown to cause what is known as coral bleaching. Coral bleaching occurs when ocean water becomes too warm or when reefs come in contact with chemicals that are toxic to their makeup. When this occurs, coral expels the algae that gives them their characteristic green, brown and orange colors. This causes drastic changes in the makeup of the reefs and causes them to be more vulnerable to threats, which can lead to coral death. We checked in with Dr. Joel Schlessinger, board-certified dermatologist and LovelySkin CEO, for his opinion on which sunscreens to wear at the beach:

“While the black and white way to protect yourself and your skin may be to look for sunscreens without oxybenzone and octinoxate, it’s not necessarily that simple. There are several very effective and elegant sunscreens that still contain oxybenzone and octinoxate, and these ingredients work very well to keep skin protected in the sun! The best way to keep skin and reefs protected is to opt for a reef-safe sunscreen when visiting the beach and saving sunscreens that contain oxybenzone and octinoxate for daily use.”

What is a reef-safe sunscreen?

The jury is still out on what constitutes a reef-safe sunscreen, but research suggests that mineral sunscreen ingredients are safest. Another rule of thumb is to avoid parabens and PABA (para-aminobenzoic acid) when around ocean life as well, as they are also known to cause damage to coral.

Mineral sunscreen, or physical sunscreen, works by blocking and deflecting harmful UV rays. These types of sunscreens are typically gentler and can be used by a wider variety of skin types. Physical sunscreens are made up of zinc oxide and titanium dioxide—two ingredients that provide effective broad-spectrum protection. There are a multitude of mineral sunscreens on the market today for all skin types and tones, so finding a formula that works for you is simple!

Bonus: To boost the power of your sunscreen while you're at the beach, try HELIOCARE Advanced Antioxidant Supplements with Nicotinamide. These dermatologist-approved supplements help boost the body's tolerance to UV rays and the power of your sunscreen without damaging coral. HELIOCARE's exclusive Fernblock Polypodium Leucotomos Extract Technology provides potent antioxidant protection while nicotinamide promotes better skin health.
