Tinosorb S Sunscreen

New Sunscreen Ingredient Tinsorb S

Living in sunny Miami, sunscreen isn’t just a seasonal accessory—it’s a daily necessity. As a dermatologist, I’ve seen firsthand how the relentless sun can affect skin health. That’s why the potential U.S. approval of Bemotrizinol (Tinosorb S), a new sunscreen ingredient long used in Europe, is exciting news for anyone seeking broad-spectrum UV protection.

What is Tinosorb S?

Tinosorb S, or Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, is a cutting-edge chemical sunscreen ingredient that may soon be found in sunscreens in the US. It’s not just any sunscreen; it’s a safe broad-spectrum SPF that efficiently absorbs both UVA and UVB rays, helping prevent sunburn and long-term skin damage. This new sunblock reflects some UV rays away from the skin while converting the rest into harmless heat.

Safety

Bemotrizinol has been used since 2000 in Europe and is considered very safe. It is rated as a “1” by the EWG. In In 1999, SCCS confirmed that there was no evidence that this compound was toxic or very allergenic. (6)

Safety to Humans

There are no concerns about hormone disruption or skin irritation. In fact, studies show it causes less contact dermatitis compared to other similar ingredients.

Safety to Marine Life and Reefs

Besides being safe for human use, Tinosorb S is also environmentally friendly. It is considered reef-safe, which means it does not contribute to the degradation of coral reefs, a significant issue with some other chemical sunscreens.

Benefits

The reason there is so much excitement about the new sunscreen bemotrizinol is that it has many benefits and few downsides. The benefits are:

Broad spectrum

Photostable

Minimal system absorption

Minimal allergy risk

Tinosorb S provides broad-spectrum protection, covering both UVA and UVB rays effectively. Its photostability ensures that it doesn’t break down in the sun, providing reliable protection throughout the day. Moreover, it does not penetrate the bloodstream, adding an extra layer of safety. It is one of the most popular sunblocks used for children in Poland.

Characteristics

This section addresses the concerns and downsides to many sunscreens. Tinosorb S has these characteristics:

Opacity : Tinosorb S is not inherently opaque on the skin. It is sheer and blends well into sunscreen formulations without leaving the white cast typically associated with physical sunscreens like zinc oxide or titanium dioxide.

Formulation Challenges : Tinosorb S is considered relatively easy to formulate compared to some other UV filters. Its solubility and compatibility with other sunscreen agents allow it to be incorporated into a wide range of sunscreen products, including lotions, creams, and sprays. It is also used to stabilize other sensitive ingredients, enhancing the overall formulation.

Comedogenicity : This new sunscreen ingredient does not typically clog pores, making it suitable for use in sunscreens designed for all skin types, including those prone to acne. It is considered a noncomedogenic sunscreen.

Stinging and Irritation : Tinosorb S does not commonly cause stinging or burning sensations when applied to the skin. Unlike some chemical sunscreens, it does not bind to TRP (transient receptor potential) receptors, which are responsible for mediating sensations such as pain, warmth, or itch. This lack of interaction reduces the risk of sensory irritation that can occur with other sunscreens.

Downsides and Side Effects

Tinosorb S has a few side effects:

Eye irritation: Many sunscreens can cause eye irritation and this has been reported with Tinosorb S so do not use a spray near your face. Instead, choose creams, lotions and sticks for your face.

Allergic reactions are not common but have been reported.

How it Works

Tinosorb S has a dual-action mechanism, distinguishing it from traditional organic sunscreens. Its molecular structure enables it to function both as a UV absorber and a UV reflector, thus providing comprehensive protection against the spectrum of ultraviolet radiation. As a UV absorber, Tinosorb S efficiently converts UV radiation into harmless heat through a process of photo-induced electron release and re-capture, which prevents the radiation from penetrating deeper skin layers and initiating cellular damage. Concurrently, its molecular configuration allows it to scatter and reflect UV rays, a characteristic more commonly associated with physical sunblocking agents like zinc oxide or titanium dioxide. This hybrid functionality not only enhances the broad-spectrum protection against both UVA and UVB rays but also contributes to the photostability of the compound, ensuring that it maintains its protective capabilities even after prolonged exposure to solar radiation. Moreover, Tinosorb S exhibits a high degree of photostability, resisting degradation and thereby maintaining its efficacy over time. This stability is particularly significant as it allows Tinosorb S to protect against photoaging and photocarcinogenesis, which are long-term risks of UV exposure. Additionally, its capability to stabilize other sunscreen ingredients enhances the overall formulation effectiveness, making Tinosorb S a valuable component in broad-spectrum sunscreen products.

Which Wavelengths Does it Block?

Tinosorb S effectively blocks a wide range of ultraviolet light wavelengths, offering broad-spectrum protection. Here are the specifics in bullet points:

UVA Protection:

Tinosorb S covers the entire UVA range from 320 nm to 400 nm.

It has peak absorption at around 340 nm, providing robust protection against deep-penetrating UVA rays that contribute to skin aging and long-term damage.

UVB Protection:

Tinosorb S also offers comprehensive coverage in the UVB range from 280 nm to 320 nm.

It features a significant absorption peak at 310 nm, which is crucial for protecting against UVB rays that cause sunburn and direct DNA damage.

This broad-spectrum coverage is beneficial for preventing both immediate effects, like sunburn, and long-term issues such as photoaging and skin cancer.

Is Tinosorb S Good for Your Skin Type?

Understanding your specific skin type is crucial for selecting the right sunscreen. I encourage you to take the Baumann Skin Type Quiz to determine the best skincare products for your unique profile. This will ensure that you use a sunscreen that complements your skin’s needs while offering optimal protection against the sun’s harmful rays.

Tinsorb Sunscreen Comparison

Both Tinosorb M and Tinosorb A2B represent advancements in sunscreen technology, offering strong, broad-spectrum protection with safety profiles suitable for sensitive skin and during pregnancy. They differ slightly in their specific UV range focus and formulation characteristics but share common benefits in photostability, hypoallergenic properties, and environmental safety.

Tinsorb M

Tinosorb M, scientifically known as Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (MBBT), is a sophisticated UV filter notable for its dual-action protection, combining organic and inorganic properties. It functions both by absorbing and reflecting UV radiation, offering broad-spectrum coverage against both UVA and UVB rays. Its unique attribute is its microfine structure, which allows it to remain on the skin’s surface, enhancing its photostability and efficacy. Tinosorb M is recognized for its minimal skin penetration, reducing concerns about systemic exposure and making it safe for use during pregnancy. It does not exhibit endocrine-disrupting effects, further affirming its safety profile. In sunscreen formulations, it is often paired with Avobenzone to stabilize the latter, thereby preventing Avobenzone’s rapid degradation in sunlight. This synergistic combination results in enhanced photostability. Despite being hypoallergenic and suitable for sensitive skin, Tinosorb M is not inherently waterproof and may require specific formulation adjustments, such as the addition of film-forming agents, to improve its water resistance. Regarding environmental impact, Tinosorb M is considered to be marine and reef safe, aligning with increasing regulatory and consumer demand for environmentally friendly sunscreen ingredients.

It is approved in Europe but as of May 2024, was not yet approved in the USA.

Tinsorb A2B

Tinosorb A2B, another advanced sunscreen ingredient, further expands the range of UV protection by specifically addressing the UVB and short UVA range. Like Tinosorb M, Tinosorb A2B is also photostable and designed to be safe for sensitive skin, including during pregnancy. It does not absorb into the skin, minimizing systemic exposure and associated risks. Additionally, Tinosorb A2B does not show any evidence of endocrine disruption. Its formulation is designed to complement other UV filters, enhancing the overall stability and effectiveness of sunscreens. Tinosorb A2B’s inclusion in sunscreens helps achieve comprehensive protection across a broader spectrum of UV light, making it a valuable component in full-spectrum sunscreens. Its efficacy and safety profile also make it a preferred choice for formulations aimed at protecting sensitive and vulnerable populations. Similar to Tinosorb M, it is considered marine and reef safe, adhering to environmental guidelines and consumer preferences for sunscreens that do not harm aquatic ecosystems.

Comparison Summary of Tinsorb Types

When comparing the different types of Tinsorb, these are the differences inthe available forms:

UV Protection Range : Tinosorb A2B offers the broadest coverage, targeting both UVB and short UVA rays effectively.

Formulation Characteristics : Tinosorb M can be formulated to improve water resistance, though it is not inherently the most water-resistant. It forms a microfine layer that helps it remain on the skin surface, but due to its larger particle size, it tends to be more opaque compared to the others.

Cosmetic Elegance : Tinosorb S is known for its excellent cosmetic elegance, being the sheerest of the three. This makes it preferred in formulations seeking minimal visibility on the skin.

Hypoallergenic Properties : All Tinosorbs are generally hypoallergenic, but Tinosorb M, staying mostly on the skin’s surface, might be considered the least likely to cause allergic reactions due to minimal skin penetration.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
