Key Benefits of Sisley Paris Sunleya SPF 50+

 
These are the key benefits you can expect from using Sisley Paris Sunleya SPF 50+:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Sisley Paris Sunleya SPF 50+ is quite moisturizing, with a moisturizing rating of 5.5 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.0 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈9.0%).

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.

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

With an SPF of 50, Sisley Paris Sunleya 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.

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.

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.
Glycerin
Est. %9
Function
Origin
Glycerin

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

Octinoxate
Est. %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.
Oxybenzone
Est. %4
Function
Origin
OxybenzoneA chemical sunscreen that protects against burning caused by UVB radiation.
Avobenzone
Est. %3
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.
Butyrospermum Parkii (Shea) Oil
Est. %2
Function
Origin
Butyrospermum Parkii (Shea) OilButyrospermum parkii oil is a liquid fraction from the more commonly used shea butter. It consists mainly of oleic acid and is used in skincare as an occlusive moisturizing and emollient ingredient. Read more on shea butter here: Butyrospermum Parkii (Shea) Butter.
Glyceryl Stearate
Est. %1.5
Function
Origin
Glyceryl StearateAn emollient and emulsifier typically derived from vegetable sources through a chemical reaction with glycerin. It provides stability, texture, and consistency to formulations. Its main function is to allow oil and water to mix.
PEG-100 Stearate
Est. %1.3
Function
Origin
PEG-100 StearateThis surfactant is more specifically classified as an emulsifier that produces oil-in-water emulsions. PEG-100 stearate can also be used as a cleansing agent.
Butylene Glycol
Est. %1
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.

Potassium Cetyl Phosphate
Est. %0.3
Function
Origin
Potassium Cetyl PhosphateA powerful emulsifier that can even mix particularly problematic water and oil blends. It is also a surfactant perfect for cleansing products that effectively rinse off oil and dirt particles from the surface of the skin.
Silica
Est. %0.3
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.
Stearyl Alcohol
Est. %0.3
Function
Origin
Stearyl AlcoholA natural fatty alcohol that thickens, stabilizes, and keeps emulsions a bright white color. It has many uses, the main one being as an emulsifier. It also acts as an opacifying agent and emollient.
Tocopheryl Acetate
Est. %0.3
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.

Allantoin
Est. %0.3
Function
Origin
AllantoinA fluffy, white powder that acts as a humectant due to its water-loving chemistry and as an exfoliant that helps to remove dead skin cells. It has also been shown to be very soothing to irritated and inflamed skin.
