Key Benefits of Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion

 
These are the key benefits you can expect from using Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion:
 

🔵🔵 Perfect Moisturizer for Normal to Dry Skin with a Balanced Texture, Neither Too Light nor Too Heavy

According to CreamScan analysis, Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion is highly moisturizing, with a moisturizing rating of 7.5 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Aluminum Hydroxide (est. ≈10.0%), and a moderate occlusivity of 5.0 out of 10, solely because of the high content of Stearic Acid (est. ≈9.9%).

This type of moisturizer is ideal for people with normal skin who want maximum hydration in a formula with a balanced texture - neither too light nor too heavy. It combines a very high concentration of humectants with a moderate amount of occlusive ingredients to deliver effective dual-action moisturizing for normal skin.

This product may also be a good choice for people with normal to dry skin for daily hydration.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion is rich (> 3%) in antioxidants, specifically Tocopheryl Acetate (est. ≈1.9%) and Ascorbyl Palmitate (est. ≈1.5%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

☀️☀️☀️ High Sun Protection for Extended Outdoor Activities and Exposure

With an SPF of 45, Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion provides high sun protection, making it ideal for prolonged outdoor activities such as hiking, gardening, sports, or spending time at the beach.

This level of SPF blocks up to 98% of UVB rays, significantly reducing the risk of sunburn. When formulated as broad-spectrum, it also protects against UVA rays, which penetrate deeper into the skin and contribute to premature aging, hyperpigmentation, and long-term damage.

This level of SPF is recommended for most skin types, including those with moderate sun sensitivity. For individuals with fair or very sensitive skin, or under intense sun exposure, a higher SPF of 50+ is advised.

📌 For optimal protection, choose products labeled broad-spectrum to ensure defense against both UVA rays, which contribute to skin aging and pigmentation, and UVB rays that cause sunburn.

It's important to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion

 
CreamScan AI identified a few things to consider before adding Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Peter Thomas Roth Max Mineral Naked Broad Spectrum SPF 45 UVA/UVB Protective Lotion is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Retinyl Palmitate and Ascorbyl Palmitate, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

Therefore, these ingredients do not generate the anti-wrinkle rating.

📌 Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Ingredients explained

Silica
Est. %65
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Aluminum Hydroxide
Est. %10
Function
Origin
Aluminum HydroxideA white mineral powder, also known as alumina, that is derived from aluminum metal. It is frequently used as an abrasive in exfoliating products and as a thickener. Aluminum oxide is also a great opacifier.
Stearic Acid
Est. %9.9
Function
Origin
Stearic AcidA saturated fatty acid found in vegetable butter and animal fats. It is an occlusive moisturizing and emollient ingredient and also helps to maintain the barrier function of the skin.
Polymethylsilsesquioxane
Est. %6
Function
Origin
PolymethylsilsesquioxaneA type of spherical powder that functions on a ball-bearing effect in which the tiny microspheres roll around on the skin and create lubricity. Polymethylsilsesquioxane offers extra slip to skincare products and makes the skin feel soft and smooth.
Triethoxycaprylylsilane
Est. %3
Function
Origin
TriethoxycaprylylsilaneA binding and coating ingredient that allows pigments like iron oxides and mica to disperse better in oily environments. This leads to more vibrant colors.
Retinyl Palmitate
Est. %2
Function
Origin
Retinyl PalmitateAn esterified form of retinol – it combines retinol and palmitic acid into one molecule. Retinyl palmitate is less irritating than retinol but also much less effective in its anti-aging and acne-reducing effects.
Tocopheryl Acetate
Est. %1.9
Function
Origin
Tocopheryl Acetate

An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.

Ascorbyl Palmitate
Est. %1.5
Function
Origin
Ascorbyl PalmitateA form of vitamin C derived from ascorbic acid and palmitic acid. It is more stable and less irritating than ascorbic acid. Unfortunately, Ascorbyl Palmitate lacks the studies to prove its anti-wrinkle efficacy.
Salix Alba (Willow) Bark Extract
Est. %1
Function
Origin
Salix Alba (Willow) Bark ExtractA potent, soothing extract from the bark of the white willow. It has potent anti-inflammatory effects due to its salicin content. Tannins from the willow bark extract have astringent effects and can aid in the skin’s healing process.
Water
Est. %0.3
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Butylene Glycol
Est. %0.3
Function
Origin
Butylene Glycol

A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.

Chlorphenesin
Est. %0.3
Function
Origin
ChlorphenesinA preservative and broad-spectrum antimicrobial agent that protects products from a wide range of bacteria and fungi.
Potassium Sorbate
Est. %0.3
Function
Origin
Potassium SorbateA preservative widely used in food and personal care products, available from natural sources or synthetically produced. Potassium sorbate works by inhibiting the growth of yeasts, molds, and some bacteria.
Tetrasodium EDTA
Est. %0.3
Function
Origin
Tetrasodium EDTAOne of the most common synthetic chelators. It can reduce the 'hardness' of water and so is often used in rinse-off products.
