Key Benefits of St. Ives Renewing Collagen Elastin Moisturizer

 
These are the key benefits you can expect from using St. Ives Renewing Collagen Elastin Moisturizer:
 

🔵🔵 Well-Suited Moisturizer for Normal to Dry Skin

According to CreamScan analysis, St. Ives Renewing Collagen Elastin Moisturizer is highly moisturizing, with a moisturizing rating of 6.6 out of 10.

Is it more humectant or occlusive? This product has relatively comparable levels of humectancy and occlusivity: a high humectancy of 6.9 out of 10, primarily due to the substantial concentration of Propylene Glycol (est. ≈6.0%), and a high occlusivity of 6.4 out of 10, mainly due to the significant content of Mineral Oil (est. ≈9.0%) and Stearic Acid (est. ≈2.5%).

This type of moisturizer is well-suited for people with normal skin who want significant hydration in a rich yet not overly thick formula. It combines a significant amount of humectants and occlusive ingredients to provide effective dual-action moisturizing.

The product’s occlusive profile suggests a texture that is rich and creamy but not overly thick, offering the potential to absorb into the skin without leaving a greasy afterfeel in most cases.

This product may also be a good choice for people with dry (but not very dry) skin for daily hydration, as it strikes a balance between significant moisturizing potential and a texture that is not too thick.

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

Ingredients explained

Water
Est. %70
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.
Mineral Oil
Est. %9
Function
Origin
Mineral OilAlso known as liquid paraffin, it is an amazing moisturizer (the second most occlusive one after Petrolatum). It is also an excellent emollient that fills the micro-cracks on the surface of the skin, making it appear smoother. Mineral oil is considered safe.
Propylene Glycol
Est. %6
Function
Origin
Propylene GlycolA clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.
PEG-100 Stearate
Est. %4
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.
Glyceryl Stearate
Est. %3
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.
Stearic Acid
Est. %2.5
Function
Origin
Stearic AcidA saturated fatty acid found in vegetable butter and animal fats. It is an occlusive moisturizing and emollient ingredient and also helps to maintain the barrier function of the skin.
Phenoxyethanol
Est. %1
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Carthamus Tinctorius (Safflower) Seed Oil
Est. %1
Function
Origin
Carthamus Tinctorius (Safflower) Seed OilA fatty oil pressed from safflower seeds that is used as an occlusive moisturizer and emollient. It contains unusually high amounts of linoleic acid (up to 70%), as well as antioxidant compounds such as vitamin E, phytosterols, and phenolics.
Triethanolamine
Est. %1
Function
Origin
TriethanolamineA clear, colorless, and highly viscous liquid, this ingredient is an excellent pH adjuster. When it is necessary to neutralize an acidic solution or to generally increase the pH of a product, triethanolamine is a common choice.
Carbomer
Est. %1
Function
Origin
CarbomerA synthetic ingredient with the ability to gel water. When used in emulsions, such as lotions and creams, carbomer can also act as an emulsion stabilizer.
Dimethicone
Est. %0.3
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.
Cetyl Alcohol
Est. %0.3
Function
Origin
Cetyl AlcoholA waxy solid fatty alcohol derived from palm oil. It is most commonly used as a co-emulsifier and affects the final aesthetic of the product, leaving a soft and silky feeling on the skin. Cetyl alcohol is also used as a viscosity controlling agent.
Disodium EDTA
Est. %0.3
Function
Origin
Disodium EDTAA synthetic chelator that helps to maintain the look and smell of a product by 'locking up' troublesome metal ions.
Fragrance
Est. %0.3
Function
Origin
FragranceUnder trade secret law, manufacturers have the right not to disclose what exactly went into the fragrance and use the unspecific word Fragrance or Parfum instead. Many fragrances are highly allergenic.
Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
Linalool
Est. %0.3
Function
Origin
LinaloolA fragrant, volatile compound naturally present in many essential oils. It has a pleasant scent and is often used in skincare products as a fragrance. People with sensitive skin should try to avoid it, or at least do a patch test before using it.
Hexyl Cinnamal
Est. %0.3
Function
Origin
Hexyl Cinnamal

A synthetic scent ingredient that produces a jasmine-like fragrance. According to the International Fragrance Association (IFRA), hexyl cinnamal is a skin sensitizer and allergen and so its use in skincare should be limited.

Hydrolyzed Elastin
Est. %0.3
