Results you may expect from using Paula's Choice Resist Youth-Extending Daily Hydrating Fluid SPF 50:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using Paula's Choice Resist Youth-Extending Daily Hydrating Fluid SPF 50:

  • Light moisturizing. It has a moisturizing rating of 3.2 out of 10.
  • Antioxidant protection.
  • Very high sun protection for prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports.

How moisturizing is it?

Lightly moisturizing: Paula's Choice Resist Youth-Extending Daily Hydrating Fluid SPF 50 has a moisturizing rating of 3.2 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 1.9 out of 10 and a moderate humectancy of 4.6 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%).

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

Anti-wrinkle efficacy

According to CreamScan analysis, Paula's Choice Resist Youth-Extending Daily Hydrating Fluid SPF 50 has a zero anti-wrinkle rating.

It contains Camellia Sinensis Leaf Extract, an ingredient marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Camellia Sinensis Leaf Extract provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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, could deliver some anti-wrinkle effects through its moisturizing action.

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

Antioxidant benefits

We estimate that Paula's Choice Resist Youth-Extending Daily Hydrating Fluid SPF 50 is rich (> 3%) in antioxidants, specifically Tocopherol (est. ≈1.3%), Chamomilla Recutita (Matricaria) Flower Extract (est. ≈1.0%), Vitis Vinifera (Grape) Seed Extract (est. ≈0.3%), and others.

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.

Sun protection

Paula's Choice Resist Youth-Extending Daily Hydrating Fluid SPF 50 has an SPF of 50 and provides very high sun protection. This level of protection is ideal for activities involving intense or prolonged sun exposure, such as spending the day at the beach, hiking, or outdoor sports. It is particularly recommended for individuals with fair skin, those at high risk of skin cancer, or in environments with intense sun exposure. Remember to apply sunscreen generously and reapply every two hours or after swimming or sweating to maintain effectiveness.

Ingredients explained

Water
Est. %65
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.
Octinoxate
Est. %7.5
Function
Origin
OctinoxateA chemical sunscreen also known as ethylhexyl methoxycinnamate. It protects against UVB, which causes the skin to burn and tan and can lead to certain types of skin cancers. For broad-spectrum protection claims, octinoxate should be paired with a UVA sunscreen.
Octisalate
Est. %5
Function
Origin
OctisalateA UVB sunscreen also known as ethylhexyl salicylate. It is normally paired with UVA sunscreens to provide broad-spectrum protection. Octisalate also protects other ingredients, like colorants and antioxidants, from deterioration due to exposure to UV light.
Glycerin
Est. %4
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Silica
Est. %3
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.
Dimethicone
Est. %2.5
Function
Origin
DimethiconeThe most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Avobenzone
Est. %2
Function
Origin
AvobenzoneA popular sunscreen that protects against UVA rays, which cause premature aging and skin cancer. Avobenzone degrades after about 30 minutes of sun exposure and becomes ineffective. It is therefore often paired with UV-filter stabilizers such as octocrylene.
Octocrylene
Est. %2
Function
Origin
OctocryleneA synthetic compound that protects skin against harmful ultraviolet light.
Tocopherol
Est. %1.3
Function
