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 Can I use salicylic acid first and then vitamin C? It’s easy to create a skincare routine, but knowing how to use it is another thing entirely. In most cases, if you’re not getting the desired skin results, it could be due to the layering of conflicting ingredients. So, is it possible that salicylic acid and vitamin C are such ingredients? Or are these active ingredients the duo that’s been missing from your skincare routine? If you want answers, stick around because today we are going to explain the benefits of salicylic acid and vitamin C and how they can be used in your daily life. What are the benefits of salicylic acid for skin? Salicylic acid is one of the most commonly used beta hydroxy acids and is favored by many people with oily, acne-prone skin. This acid is derived from willow bark, and unlike its water-soluble relatives (called alpha-hydroxy acids), salicylic acid is oil-soluble, which means it can penetrate deeper into the lower layers of the skin. Once it reaches the lower layers, it can help unclog pores of excess sebum, dirt, bacteria, debris, and impurities. This results in clearer skin tones and greater definition. Not only does salicylic acid benefit the underlying layers, but the outer surface of the skin benefits as well. When applied to the skin, salicylic acid removes the buildup of dead skin cells. This is accomplished by breaking the bonds that hold dead cells to the surface. Over time, this can cause the complexion to look dull and prone to acne, blackheads, and other blemishes. If you’d like to learn more about salicylic acid and how it can improve your skin, check out this dedicated blog post from a beauty insider. What are the benefits of vitamin C for skin? Vitamin C is considered one of the most powerful antioxidants, which means it is very effective at fighting free radicals and preventing them from causing further skin damage. Examples of free radicals include pollution, central heating, UV rays and harsh climate. They attack proteins, fats and cell membranes as soon as they come into contact with the skin, causing signs of premature aging such as fine lines and wrinkles as well as hyperpigmentation, flaky patches of skin and loss of elasticity. Many people usually prefer to use vitamin C in their morning routine as this ingredient gives the complexion a radiant glow. You’ll also find that vitamin C can target areas of hyperpigmentation, plumping the skin and reducing the appearance of fine lines and wrinkles. The thing about vitamin C is that there are a lot of outdated studies going back to the 1950s that describe vitamin C as an unstable skin component. Thanks to improvements in modern technology, this is no longer the case as all products now contain a stable form of vitamin C. Visit The Beauty Insider to learn more about vitamin C. So please check out our blog post. Can I use salicylic acid first and then vitamin C? Yes, you absolutely can. In fact, it’s thought that using salicylic acid before using vitamin C ensures it penetrates faster and works faster. This is an efficient way to utilize two power sources, and the reason has to do with pH. For example, the skin’s natural pH is about 4.7, making it slightly acidic. Salicylic acid and vitamin C are also both acidic, and you’ll find that vitamin C is absorbed quickly into the skin. Therefore, using salicylic acid beforehand can increase the acidity of the skin and allow vitamin C to penetrate into the skin faster. While this is considered an effective way to combine two powerful ingredients, you need to be aware of your skin type and how it reacts to certain active ingredients. Even people with perfect, normal skin can experience skin sensitivity and irritation. Therefore, always consult a doctor or dermatologist before using any new products on your skin. It’s also important to follow skin application rules. In this case, you need to use the product correctly to ensure you get the best results for your skin. If you’re not sure what I mean, the basic rule for skin is to start with the thinnest consistency and work your way up to the thickest consistency. This prevents a barrier from forming on the surface, preventing other active ingredients from penetrating the skin. Can I use salicylic acid at night and vitamin C in the morning? Yes, absolutely, this is considered the most effective way to get returns without any adverse side effects. This is because there is enough time between applications to ensure that the skin’s pH levels return to balance. You’ll also find that Vitamin C is rich in antioxidants and is perfect for use in the morning to ensure your skin is protected and looking its healthiest. Due to the small size of salicylic acid molecules, it is an acid that is able to reach the deepest parts of the skin. While this is effective at keeping skin clear, it also increases the risk of irritation and photosensitivity. Therefore, many people prefer to use powerful BHAs in their evening routine without exposure to UV rays, pollution, or harsh weather. Warning: If you avoid using sunscreen every day, none of these ingredients will do what your skin needs. The combination of chemical peels and powerful ingredients increases the risk of further damage to the skin’s surface. Use SPF 50 every day to keep your skin protected and your lipid barrier healthy, even on cloudy days, keeping your skin in top condition.
