FDA Proposes New Sunscreen Regulations; Experts React
The FDA is updating its position on OTC sunscreens, and according to the new proposal, several popular ingredients require more data. Guidelines do, however, note that zinc oxide and titanium oxide are safe to use. The FDA evaluated 16 sunscreen ingredients and determined that 12 of them should be required to submit additional safety data. Two ingredients—PABA and trolamine salicylate—are considered unsafe for sunscreen.
“Since the initial evaluation of these products, we know much more about the effects of the sun and about sunscreen’s absorption through the skin,” FDA Commissioner Dr. Scott Gottlieb says in a statement.
While largely supportive of the FDA’s new proposal and efforts to educate consumers about sunscreen use, top dermatologists worry it does not go far enough and fails to make it easier for new ingredients to be approved.
The FDA also proposed updates on sunscreen safety, sun protection factor (SPF) requirements, and the effectiveness of insect repellent/sunscreen combinations.
Among the highlights:
• The maximum sun protection factor on sunscreen labels would be raised from SPF 50+ to SPF 60+.
• Sunscreens with SPF values of 15 and higher will be required to be broad-spectrum, and broad-spectrum protection against ultraviolet A radiation must also increase as SPF increases.
• New sunscreen label requirements will include a list of active ingredients on the front of the bottle.
• Products that combine sunscreens with insect repellents are not generally considered safe and effective.
• Sunscreen lotions, sprays, oils, creams, gels, butters, pastes, ointments, and sticks offer proven protection. Wipes, towelettes, washes, shampoos, and other forms of sunscreen must now be categorized as new drugs because the FDA has not seen data showing efficacy.
• Powder sunscreens may be effective, but more safety and efficacy data is needed.
The new proposal may not go far enough, says Heidi A. Waldorf, MD, a dermatologist in private practice in Nanuet, NY and an Associate Clinical Professor of Dermatology at Mount Sinai Hospital in New York City.
“The increase of top SPF rating from 50 to 60 won’t be a huge change,” she says. “To me, the biggest change was taking away the SPF 100 [in 2011] and all-day protection labeling.”
A second-generation dermatologist, Dr. Waldorf grew up with SPF 15 as the maximum, and used it to effectively protect against sunburns and tans, but she has seen patients who used an SPF 100 who weren’t effectively protected. “The very high numbers often give people a false sense of safety. They think they don’t need to apply it as heavily or as frequently.”
In addition to the two ingredients considered unsafe, there will be 12 additional chemicals listed as having unknown safety, including some that are very commonly used. “It won’t keep any from being used. It just suggests more investigation,” she notes. The FDA has asked the sunscreen industry to conduct additional testing on products with these ingredients.
Moreover, there is nothing in the proposal that allows for new sunscreen ingredients to get approved more expeditiously, Dr. Waldorf says. “While I am happy using titanium dioxide and zinc oxide sunscreens and the newest formulations work for many skin types, they can appear ‘ashy’ or white on the darkest skin making them unusable, and there are patients who just won’t use them because of the feel,” she says. “From a practical standpoint, we need chemical sunscreens to have a range of sunscreen options acceptable to a broad heterogeneous population.”
Calling the FDA recommendations “a positive step forward,” Ilana DeLuca MD, PhD, FAAD, an Assistant Clinical Professor in the Department of Dermatology at the George Washington School of Medicine and Health Sciences in Washington, DC, says it’s important to understand that the 12 organic filters that the FDA is asking for more data on are not necessarily unsafe, and patients shouldn’t be discouraged from applying sunscreens containing these ingredients. “At the same time, absorption data on these ingredients is needed, especially since we’re asking patients to apply sunscreen every single day to the face at a minimum in order to prevent skin cancer. We should be able to comfortably make that recommendation for all active filters, not just zinc and titanium.”
Jeanine Downie, MD, Director of image Dermatology, in Montclair, NJ, largely agrees with the FDA proposal. “I think it is excellent that they are no longer allowing sunscreen and insect repellent to coexist together, as having them both together decreases the effectiveness of the sunscreen by at least 30 percent, if not higher, depending on what study you look at.”
She is glad that the FDA will be reviewing sunscreen wipes, towelettes, and shampoos. “I am suspicious about these forms of sunscreen,” she says. “Overall, I…agree with what the FDA is doing to help patients put sunblock on, reapply sunblock, and protect from themselves from skin cancer. I think the next step should be discouraging sunblocks less than an SPF 15 being on the market.”
The new legislation will help give consumers better information on the sunscreens that they are using, adds Joshua Zeichner, MD, Director of Cosmetic and Clinical Research, Department of Dermatology at The Mount Sinai Hospital in New York City. “Proper use of sunscreen is one of the most important ways that we can protect ourselves against the development of skin cancers, so I support any new FDA actions that help educate consumers on their use,” he says.
FDA is seeking public comment on the proposal. Those familiar with the agency’s action say feedback from dermatologists will be valuable. To comment: bit.ly/SPFcomment
FDA Approves Janssen’s Tremfya One-Press
The FDA has approved Tremfya One-Press, a single-dose, patient-controlled injector for adults with moderate to severe plaque psoriasis. Tremfya (guselkumab) from the Janssen Pharmaceutical Companies of Johnson & Johnson is the first medication of its kind to offer the One-Press patient-controlled injector. It fits comfortably in the hand and offers a controlled injection that hides the needle. Tremfya is administered as a 100mg subcutaneous injection once every eight weeks, after starter doses at weeks 0 and 4. Tremfya is intended for use under the supervision of a physician, and patients may self-inject with Tremfya One-Press after physician approval and proper training.
The design of One-Press allows patients to control the rate and pressure of their injection. A soft click indicates when administration is complete, resulting in nearly 99 percent of patients reporting a successful first injection. One-Press also includes a safety system that protects the needle after use.

Altreno Launch: Focus on Education
As part of the launch of Altreno (tretinoin) Lotion, 0.05% from Ortho Dermatologics, dermatologists Doris Day, MD and Joshua Zeichner, MD and colleagues spoke at the Harvard Club in New York City earlier this year. Altreno is indicated for the treatment of acne, and its formulation may be especially appealing to adults. Estimates suggest that nearly four times as many women suffer from acne as men. Altreno Lotion is the first and only tretinoin lotion, and it was designed with women in mind, because it provides efficacy, tolerability, and once-daily dosing in an elegant lotion formulation to help achieve beautiful skin by working to treat their acne.
Some readers noted that a statement in the Clinical Connections series article, “Highlighting the Role of the NP and PA: Insights from the Dermatology Education Foundation,” could be unclear (February 2019). The authors state, “A key challenge in providing collaborative care with dermatologists is proper training with access to the dermatologist. Proper training of an NP or PA by a dermatologist over the first few years can be similar to a medical residency for a dermatologist. Patients are initially seen by the dermatologist, and then over time, the NP and PA may perform evaluation and treatment plans that are reviewed with the dermatologist. Eventually, the NP and PA may independently see patients and maintain their own schedule. These first few years of training are essential and necessary for the NP/PA to function competently and autonomously within dermatology practices.”
In keeping with the theme of the piece, which is focused on collaboration between PAs or NPs and dermatologists, the statement that, “the NP and PA may independently see patients and maintain their own schedule,” was intended to indicate that the established PA or NP likely will not need to see each patient side-by-side with the supervising dermatologist. It was not intended to suggest that these individuals will establish individual practices.
It is essential that all parties be aware of and adhere to scope of practice and supervision requirements, which are established at the state level.
It’s been about a decade since any new neuromodulators came to market in the US, which is why enthusiasm about Evolus’ Jeuveau is so palpable. The 900kDA neurotoxin scored the coveted FDA nod in early 2019 for smoothing glabellar lines and is expected to be available in physicians’ offices this spring. David Moatazedi, Evolus Chief Executive Officer, and Michael Jafar, Evolus Chief Marketing Officer, spoke with Practical Dermatology® about what we can expect from Evolus and the company’s plan to build a portfolio of products designed specifically for aesthetics.
1. Disruptive Launch
David Moatazedi and Michael Jafar: Evolus is the first company in nearly a decade to enter the fast-growing US aesthetic neurotoxin market. We are excited to launch a new chapter in aesthetics with the recent FDA approval of Jeuveau. It is the first-known FDA approved 900kDA neurotoxin in the US since Botox Cosmetic and the first neurotoxin dedicated exclusively to aesthetics. Jeuveau was designed specifically to go head-to-head with Botox. Jeuveau will be available at physician offices in Spring 2019. We are planning for a high-impact, disruptive launch of Jeuveau powered by our technology platform designed to eliminate the friction points that exist for customers today.
2. Tapping into the Millennial Market
Mr. Moatazedi and Mr. Jafar: Jeuveau will be introduced as a new toxin with a fresh new look, and Evolus is strategically focused on tapping into the millennial mindset, which will be reflected in the company’s approachable communication style, campaign assets, and core brand DNA.
3. Working Together
Mr. Moatazedi and Mr. Jafar: Our manufacturing partner is Daewoong Pharmaceuticals, which is one of the largest pharmaceutical companies in South Korea. We have a great, long-standing relationship with Daewoong. Working with our partners in South Korea has been a collaborative experience. We built a modern, state-of-the-art, Good Manufacturing Practice (GMP)-compliant manufacturing facility that has allowed us control and oversight of the quality and safety standards in which Jeuveau is manufactured.
4. Bright Future
Mr. Moatazedi and Mr. Jafar: We are committed to providing physicians and their patients with expanded choices in medical aesthetic treatments and procedures. Jeuveau is our first product launch that anchors us in this mission. Our goal is to not only grow the aesthetics market, but to also raise the bar for both physicians and their patients. We look forward to continuing to build a portfolio of products designed specifically for aesthetics.
5. The Comeback Kid
Mr. Moatazedi and Mr. Jafar: In May of 2018, a complete response letter (CRL) was issued with deficiencies isolated to chemistry, Manufacturing, and Controls (CMC) processes. (Editor’s note: at that time, the FDA rejected Evolus’ application.) No clinical, safety, or efficacy deficiencies were cited. We were able to address the questions quickly and resubmit ahead of our self-imposed timeline of 90 days, ultimately allowing us to move forward as planned. We completed our FDA re-submission in August 2018 and in the same month our Biologics License Application was accepted by the FDA and we were granted a six-month review.
With Adam Friedman, MD, FAAD
Everyone is talking about or using cannabidiol (CBD) oil to treat a laundry list of diseases, conditions and symptoms including dermatologic concerns such as psoriasis, atopic dermatitis, and wound healing, but little was known about dermatologists’ awareness of cannabinoids as therapeutics until know. Adam Friedman, MD, FAAD, Professor and Interim Chair of Dermatology and Director of the Residency Program and Translational Research at the George Washington University School of Medicine & Health Sciences in Washington, DC, and colleagues surveyed 531 dermatologists to get a better idea about their attitude and awareness on cannabinoids as therapeutics, and it turns out there’s a lot they need to learn.
Why is this topic important to study?
Dr. Friedman: Cannabinoids represent a broad class of plant, human, and synthetic bioactive agents which have tremendous reactivity in the living system, yet due to the negative social stigma and federal roadblocks, both our understanding and even more so, our translation to bedside has been undermined and therefore limited. We have a lot of catch up to do—work which will require more time and energy to even begin to keep pace with the exponentially increasing number of state approvals for both medical and recreational cannabis. Consumers and patients alike are interested and have questions. Physicians need to provide guidance and answers and therefore we wanted to assess dermatologists’ and dermatology providers’ comfort with and fund of knowledge on medical cannabinoids.
Describe the research and your findings.
Dr. Friedman: Our survey study revealed several key messages. First, dermatologists are being approached by their patients with questions on this subject matter, and this is more likely to occur in states where medical cannabis is legalized. Second, while more than 90 percent of respondents agreed that this is an important area for R&D and 85 percent thought medical cannabinoids should be legal, more than 80 percent were not comfortable with their understanding or knowledge on this subject matter, which is not surprising given 65 percent of respondents incorrectly responded that CBD has psychoactive effects.
What is next step?
Dr. Friedman: First things first, let’s educate our colleagues on the current state of the science and practice. This is already starting to manifest. We need sessions at both local and national conferences as well as those who are ingrained in this field to publish, publish and publish. Next, we need industry to take interest, support investigators, and collaborate to bring new cannabinoid-based drugs to the market. This is a great opportunity for the broader dermatology community as a whole to unite under a common and novel goal. Wouldn’t it be great to have something new in the tool chest?
