Does Paula's Choice 5% Vitamin C Sheer Facial Moisturizer SPF 50 work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Paula's Choice 5% Vitamin C Sheer Facial Moisturizer 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.

Basic moisturizer for oily skin

According to CreamScan analysis, Paula's Choice 5% Vitamin C Sheer Facial Moisturizer SPF 50 is lightly moisturizing, with a moisturizing rating of 3.2 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a low occlusivity of 0.8 out of 10 and a moderate humectancy of 5.6 out of 10, primarily due to the high content of Glycerin (est. ≈5.0%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula with a minimal amount of occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

Since it contains a moderate amount of humectants, it can also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Paula's Choice 5% Vitamin C Sheer Facial Moisturizer SPF 50 has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically 3-O-Ethyl Ascorbic Acid, Ascorbyl Glucoside, and Tetrahexyldecyl Ascorbate. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. 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.

Rich in skin-protecting antioxidants

We estimate that Paula's Choice 5% Vitamin C Sheer Facial Moisturizer SPF 50 is rich (> 3%) in antioxidants, specifically 3-O-Ethyl Ascorbic Acid (est. ≈5.0%).

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.

Very high sun protection for prolonged sun exposure, all skin types, and high-risk conditions

With an SPF of 50, Paula's Choice 5% Vitamin C Sheer Facial Moisturizer SPF 50 provides very high sun protection, suitable for intense sun exposure in tropical climates, beach vacations, or high-altitude environments.

This level of SPF blocks 98% or more of UVB rays, offering the highest level of defense against sunburn. Broad-spectrum formulations also provide strong protection against UVA rays, which are responsible for skin aging, pigmentation, and DNA damage.

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 is ideal for all skin types, particularly fair, sensitive, or post-treatment skin (e.g., after laser or chemical procedures). It is also highly recommended for individuals at greater risk of skin cancer.

For extended outdoor activities or water exposure, choose a water-resistant formula and reapply every two hours for maximum effectiveness.

Ingredients explained

Water
Est. %60
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. %5
Function
Origin
Glycerin

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

Silica
Est. %5
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.
3-O-Ethyl Ascorbic Acid
Est. %5
Function
Origin
3-O-Ethyl Ascorbic AcidA derivative of vitamin C. Its stability in skincare formulations is better than ascorbic acid’s, although clinical studies are yet to indicate whether it has the same collagen-boosting benefits.
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.
Ascorbyl Glucoside
Est. %1.3
Function
Origin
Ascorbyl GlucosideA derivative of vitamin C. It is more stable and less irritating than ascorbic acid. There are unfortunately no clinical studies on ascorbyl glucoside’s anti-pigment or anti-acne efficacy alone.
Dimethicone
Est. %1
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.
Propanediol
Est. %0.3
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Tetrahexyldecyl Ascorbate
Est. %0.3
Function
Origin
Tetrahexyldecyl AscorbateA lipid-soluble form of vitamin C that is more stable and less irritating than ascorbic acid. According to a recent clinical study, THDA has all the capabilities of regular vitamin C, including anti-wrinkle and anti-pigment activity.
Acetyl Zingerone
Est. %0.3
Function
Origin
