Key Benefits of La Roche-Posay Rosaliac UV Legere

 
These are the key benefits you can expect from using La Roche-Posay Rosaliac UV Legere:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, La Roche-Posay Rosaliac UV Legere is quite moisturizing, with a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.8 out of 10 and a very high humectancy of 9.3 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and Niacinamide (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

Considerable Anti-Wrinkle Efficacy

According to CreamScan analysis, La Roche-Posay Rosaliac UV Legere has a moderate anti-wrinkle rating of 4.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, La Roche-Posay Rosaliac UV Legere also contains contains Ascorbyl Glucoside and Caffeine, 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. Therefore, these ingredients do 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.

Rich in Skin-Protecting Antioxidants

We estimate that La Roche-Posay Rosaliac UV Legere is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

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.

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.

Isononyl Isononanoate
Est. %9
Function
Origin
Isononyl IsononanoateAn ester of a branched fatty acid with a branched fatty alcohol. It is an easily spreadable emollient that has a silky, dry, non-greasy feel on the skin.
Glycerin

Function
Origin
Glycerin

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

Octocrylene
Est. %4
Function
Origin
OctocryleneA synthetic compound that protects skin against harmful ultraviolet light.
Niacinamide
Est. %3
Function
Origin

Also known as vitamin B3, this ingredient is a true superstar with confirmed moisturizing, anti-acne, hyperpigmentation, and antioxidant benefits. Two studies confirm its significant anti-wrinkle efficacy.

Octisalate
Est. %2.5
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.
Diisopropyl Sebacate
Est. %2
Function
Origin
Diisopropyl Sebacate
Dimethicone
Est. %1.5
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.
Sucrose Tristearate
Est. %1.3
Function
Origin
Sucrose Tristearate
Avobenzone
Est. %1
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.
Cyclohexasiloxane
Est. %0.3
Function
Origin
CyclohexasiloxaneA clear silicone fluid with very low viscosity that is commonly used as a solvent and emollient. It has excellent spreadability, rubs in quickly, and leaves a silky smooth after-feel on the skin.
Ammonium Polyacryloyldimethyl Taurate
Est. %0.3
Function
Origin
Ammonium Polyacryloyldimethyl TaurateAn emulsion stabilizer and thickener with gelling properties. The products containing this ingredient frequently feature lightweight and refreshing aesthetics upon application to the skin.

Caffeine
Est. %0.3
Function
Origin
CaffeineAn antioxidant compound that is obtained from coffee and tea leaves. It increases the microcirculation of blood in the skin and is claimed to be able to reduce the appearance of orange peel skin (although the research is lacking).
Sodium Citrate

Xanthan Gum
Est. %0.3
Function
Origin
Xanthan GumA natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
