Does No7 Stay Perfect Foundation SPF 30 work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using No7 Stay Perfect Foundation SPF 30:

  • Strong occlusive moisturizing. This exceptionally occlusive moisturizer, ideal for dry and very dry skin, has a moderate moisturizing rating of 5.8 out of 10, impaired by the lack of humectants.
  • Moderate to high sun protection for daily outdoor activities

Moisturizer with the right occlusivity for dry to very dry skin, ideally to be used with extra humectants

According to CreamScan analysis, No7 Stay Perfect Foundation SPF 30 is quite moisturizing, with a moisturizing rating of 5.8 out of 10.

Is it more humectant or occlusive? Significantly more occlusive. It has a low Humectancy of 1.5 out of 10 and a maximum Occlusivity of 10 out of 10, due to the high content of Caprylyl Methicone (est. ≈9.0%), Dimethicone (est. ≈6.0%) and Phenyl Trimethicone (est. ≈4.0%).

This type of product, when used as a standalone moisturizer, can deliver an exceptional level of occlusive hydration that is adequate for dry to very skin. The occlusive profile of No7 Stay Perfect Foundation SPF 30 suggests a rich, thick texture, making it perfectly suited for dry skin.

However, it contains a low level of humectants, and people with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

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

Moderate to high sun protection for daily outdoor activities

With an SPF of 30, No7 Stay Perfect Foundation SPF 30 provides moderate to high sun protection, making it suitable for daily use during moderate sun exposure, such as commuting or light outdoor activities.

This level of SPF offers excellent defense against UVB rays, blocking up to 97% of harmful radiation. When labeled as broad-spectrum, these products also protect against UVA rays, which are responsible for skin aging and hyperpigmentation.

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 works well for skin types mildly prone to sunburn. It is particularly suitable for low-to-moderate UV index environments and non-tropical climates. However, it is not recommended for prolonged outdoor exposure or intense UV conditions. Reapplication every two hours is essential 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.
Caprylyl Methicone
Est. %9
Function
Origin
Caprylyl MethiconeA liquid silicone with occlusive moisturizing properties. Being compatible with natural oils is a challenge for most silicones, but caprylyl methicone plays well with all types of oils.
Dimethicone
Est. %6
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.
Phenyl Trimethicone
Est. %4
Function
Origin
Phenyl TrimethiconeA silicone fluid that is used as an occlusive moisturizer. It applies smoothly to the skin and reduces the tack associated with organic oils.
Octinoxate
Est. %3
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.
Trimethylsiloxysilicate
Est. %2.5
Function
Origin
TrimethylsiloxysilicateAn occlusive moisturizing and emollient silicone resin that smoothes and softens the appearance of the skin. It also protects a product from rinsing away too easily with water, sweat, or friction.
Mica
Est. %2
Function
Origin
MicaA mineral powder made up of silicates with several functions (the main one being as a colorant). It has a shimmery appearance, making it highly desirable in certain cosmetic products. Mica also helps the product to apply more smoothly.
Silica
Est. %1.5
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.
PEG-9 Dimethicone
Est. %1.3
Function
Origin
PEG-9 Dimethicone
Titanium Dioxide (CI 77891)
Est. %1
Function
Origin
Titanium Dioxide (CI 77891)One of two the most commonly used mineral sunscreens. It can absorb UV light, including UVB – which causes burning, tanning, and even skin cancer. Also used as a colorant, titanium dioxide gives a product a bright white color.
Bis-Isobutyl PEG/PPG-10/7/Dimethicone Copolymer
Est. %0.3
Function
Origin
Bis-Isobutyl PEG/PPG-10/7/Dimethicone Copolymer
Butylene Glycol
Est. %0.3
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.

Disteardimonium Hectorite
Est. %0.3
Function
Origin
Disteardimonium HectoriteA clay ingredient that functions primarily as a viscosity controlling agent that thickens all types of formulas. Disteardimonium hectorite imparts a smooth, velvety feel, making it a luxurious addition to any formula.
Magnesium Sulfate
Est. %0.3
Function
Origin
Magnesium SulfateA naturally occurring mineral that is commonly used in skincare products as a bulking agent. It helps to control the viscosity of products by making them thicker.
Phenoxyethanol
Est. %0.3
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.
Triethyl Citrate
Est. %0.3
Function
Origin
Triethyl Citrate
Panthenol
Est. %0.3
Function
Origin
PanthenolA popular soothing and moisturizing derivative of vitamin B5. Panthenol is particularly beneficial for dry, flaking, burned, or damaged skin. It is used to alleviate the symptoms of a rash, dermatitis, eczema, chapped lips, and sunburn.
Triethoxycaprylylsilane
Est. %0.3
Function
Origin
TriethoxycaprylylsilaneA binding and coating ingredient that allows pigments like iron oxides and mica to disperse better in oily environments. This leads to more vibrant colors.
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.

Caprylyl Glycol
Est. %0.3
Function
Origin

Ethylhexylglycerin
Est. %0.3
Function
Origin

Tetrasodium EDTA
Est. %0.3
Function
Origin
Tetrasodium EDTAOne of the most common synthetic chelators. It can reduce the 'hardness' of water and so is often used in rinse-off products.
BHT
