Does Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion:

  • A bit of moisturizing. It has a moisturizing rating of 1.8 out of 10.
  • Little anti-wrinkle effect: Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion has an anti-wrinkle rating of 0.1 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.
  • Moderate to high sun protection for daily outdoor activities

Slight Moisturizing When Used Alone

According to CreamScan analysis, Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion is slightly moisturizing, with a moisturizing rating of 1.8 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of Humectancy and Occlusivity: a low Humectancy of 2.7 out of 10 and a low Occlusivity of 0.8 out of 10.

This type of product provides relatively light moisturizing on its own but can contribute to overall moisturizing efficacy when used as part of a skincare routine, alongside another moisturizer.

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

Little anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion has a minimal anti-wrinkle rating of 0.1 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%), 
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion also contains Retinyl Palmitate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Retinyl Palmitate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to 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.

Moderate to high sun protection for daily outdoor activities

With an SPF of 30, Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion SPF 30 Sunscreen Lotion provides moderate to high sun protection, making it suitable for daily use during moderate sun exposure, such as commuting or light outdoor activities.

This level of SPF offers excellent defense against UVB rays, blocking up to 97% of harmful radiation. When labeled as broad-spectrum, these products also protect against UVA rays, which are responsible for skin aging and hyperpigmentation.

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.

This level of SPF works well for skin types mildly prone to sunburn. It is particularly suitable for low-to-moderate UV index environments and non-tropical climates. However, it is not recommended for prolonged outdoor exposure or intense UV conditions. Reapplication every two hours is essential to maintain effectiveness.

Ingredients explained

Water
Est. %55
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.
Homosalate
