The Sunscreen Dilemma - A Dermatologist's Perspective
PatientPoint Launch • July 30, 2019
Before we delve into the current problems surrounding sunscreen, I want to begin by saying that I believe in the importance of sunscreen. I use sunscreen when I go outside (admittedly not always as often as I should), I use sunscreen on my two-year-old son, and my pregnant wife uses sunscreen as well. You can also reference our previous blog post on the subject by clicking here. Recently, several reports have cast doubt on the safety of sunscreen for both humans and the environment as whole. I believe it is important that we address these concerns and put them into perspective.
The most recent concern was raised by a recent study published in JAMA (The Journal of the American Medical Association). This study pertained to what we call chemical sunscreens and it demonstrated that when people applied these chemical sunscreens in the recommend amounts and at the recommend intervals, significant amounts of the active chemical agents found in the sunscreen were detectable in the blood. The chemicals in question include avobenzone, oxybenzone, octocrylene, and ecamsule and do not include zinc oxide or titanium dioxide. Zinc and titanium are ingredients commonly found in physical sunscreens.
The other new issue that raised concerns over sunscreen revolved around the new regulations in Hawaii, and Key West banning the use of oxybenzone and octinoxate (chemical sunscreen ingredients) as of January 1, 2021 and discussion of bans in other areas. These actions were taken in response to concerns that sunscreen may be affecting the aquatic environments in these areas, particularly the coral reef ecosystems. In addition, there is consideration to ban titanium dioxde and any products containing mineral oil or petrolatum (Vaseline). Hawaii.com discourages the use of titanium dioxide and recommends certain sunscreens that they deem safe. Some of the sunscreens they recommend are not typically thought of as quality sunscreens and as such, I do not recommend many of them to my patients. There are a few on their list that I would consider using such as Reef Safe Oxybenzone Free Biodegradable SPF 50 Sunscreen and Banana Boat Simply Protect SPF 50+ Sunscreen. While these are not my first choices and I have never used them, I do feel that they could be effective.
So what does all of this mean for us? I believe that the study published in JAMA raises a good question. Are these ingredients safe for humans and in particular are they safe for children and safe for use during a pregnancy? It also pushes the medical community, and the companies that make products with these ingredients, to answer this question and do so in a timely manner. Until we have the answers, if you are concerned, my recommendation is to use a physical sunscreen that contains either zinc oxide or titanium dioxide and if you are concerned about the oceans just go with old-fashioned zinc oxide. Zinc oxide has been around for quite some time and has a great track record with regard to safety. There are many over the counter sunscreens that contain zinc oxide and we sell several types in our office. Also remember that if you have specific questions that need to be answered, ask your health care provider. We are happy to answer these questions, address your concerns and make recommendations based on the best available information.
At Pine Belt Dermatology & Skin Cancer Center, we believe education is key to protecting and maintaining healthy skin. July is significant for skin health, featuring both UV Safety Awareness Month and World Skin Health Day on July 8 . These occasions highlight the importance of sun protection and raise awareness of common concerns, such as hyperpigmentation and melasma . Understanding how ultraviolet (UV) exposure affects your skin helps prevent long-term damage and supports a healthier, more even complexion. Why UV Protection Matters The sun emits ultraviolet rays that can damage skin even on cloudy days. While many associate UV exposure with sunburn, its effects are broader. Repeated UV exposure accelerates skin aging, increases skin cancer risk, and contributes to pigmentation disorders. Common effects of excessive UV exposure include: • Sunburn and skin irritation • Premature aging, including fine lines and wrinkles • Dark spots and uneven skin tone • Increased risk of skin cancer • Worsening of hyperpigmentation and melasma Daily sun protection is one of the most effective ways to maintain healthy skin and reduce preventable damage. What Is Hyperpigmentation? Hyperpigmentation is a common condition where areas of skin become darker than the surrounding tissue due to excess melanin production. Multiple factors can contribute to hyperpigmentation, including: • Sun exposure • Acne scars and inflammation • Hormonal changes • Skin injuries or irritation • Certain medications While hyperpigmentation is mostly harmless, many seek treatment to improve skin tone as well as restore confidence. Understanding Melasma Melasma is a type of hyperpigmentation that shows up as brown or gray-brown patches, typically on the cheeks, forehead, nose, and upper lip. Melasma is frequently associated with: • Hormone changes during pregnancy • Birth control medications • Hormone replacement therapy • Genetic predisposition • Sun exposure Although melasma is not dangerous, it can be difficult to treat because UV exposure frequently triggers or worsens it. Even minimal sun exposure can increase pigment production and make discoloration more noticeable. Protecting Your Skin from UV Damage Whether you are concerned about skin cancer, hyperpigmentation, or melasma, daily sun protection is essential. Dermatologists suggest: • Using sun lotion with SPF 30 or higher every day • Reapplying sunscreen every two hours when outdoors • Wearing wide-brimmed hats and protective clothing • Seeking shade during peak sunlight hours • Wearing UV-protective sunglasses • Avoiding tanning beds Consistent sun protection helps prevent new pigmentation issues. World Skin Health Day: A Reminder to Prioritize Skin Care Observed annually on July 8, World Skin Health Day encourages preventive steps to maintain healthy skin. This is a reminder to perform regular self-exams, schedule dermatology visits, and address concerns early. If you notice persistent dark spots, changes in pigmentation, or new skin lesions, seek an expert assessment to determine the cause and identify treatment options. Supporting Healthy Skin Year-Round UV Safety Awareness Month and World Skin Health Day remind us that protecting your skin is an investment in long-term health. Practicing sun safety and understanding conditions like hyperpigmentation and melasma help preserve your skin’s health, appearance, and function.

When a ‘Rash’ Might Be Something More Serious At Pine Belt Dermatology & Skin Cancer Center, we recognize that rashes are common and frequently resolve quickly with minimal treatment. However, some rashes may signify underlying conditions that require prompt medical attention. Identifying when a rash is more than a minor irritation is key to protecting your health. Comprehending Common vs. Concerning Rashes Most everyday rashes result from irritants, allergies, heat, or minor infections and typically improve within a few days with over-the-counter treatments. However, if a rash lasts longer, worsens, or appears with other symptoms, it may signal a more serious issue. Identifying the difference between a routine rash and one that requires medical evaluation helps avoid complications and ensure appropriate care. Warning Signs to Watch For Certain features may indicate a rash requires clinical assessment, including: Rapidly spreading or worsening rash Severe pain, swelling, or blistering Signs of infection such as pus, warmth, or red streaks Fever or flu-like symptoms accompanying the rash A rash that does not improve after several days of treatment Dark, purple, or bruised-looking areas on the skin For example, a rash with fever may indicate a viral or bacterial infection, whereas painful blistering can suggest conditions such as shingles. In rare cases, rashes may signal autoimmune disorders or severe allergic reactions. Rashes That May Point to Underlying Conditions Some rashes may be linked to broader health concerns, including conditions that cause inflammation in the skin and other organs: Allergic reactions that may escalate into further severe responses Infections that spread beyond the skin if untreated Medication reactions that require immediate adjustment Persistent or unusual skin changes may be early signs of skin cancer or precancerous conditions, especially if they do not heal or continue to change over time. Why Early Evaluation Matters Delaying care for a worrisome rash may allow the underlying condition to progress. Early diagnosis improves treatment outcomes and helps prevent discomfort and complications. A dermatology specialist can assess the rash’s appearance, location, and progression, and may recommend diagnostic tests if needed. This approach assures treatment addresses the underlying cause, not just the visible symptoms. When to See a Dermatology Specialist If you are unsure about your rash, it is best to err on the side of caution. Consider seeking care if: The rash is persistent, painful, or unusual in appearance Over-the-counter treatments are not effective You experience additional symptoms such as fever or fatigue The rash interferes with your daily comfort or quality of life At Pine Belt Dermatology & Skin Cancer Center, our experienced providers supply comprehensive skin evaluations and customized treatment plans.
