It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen~3.6–4.4%

OctinoxateEthylhexyl MethoxycinnamateUVBOctinoxate. When used in higher concentrations, works as a sunscreen protecting the skin from UVB rays. When used in lower concentration, helps to preserve the product formulation. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can be irritating~3.2–3.9%

Titanium Dioxide Mineral UVBUVA2 Photo-stable Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products.

What the product description says

“Reduces pigmentation, brightens skin, and improves the skin’s health and quality”

Source: SpaceNK EU

This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).

Ethyl linoleateEffect: LowHelps reduce acne and blemishes. Helps to soften the upper layer of the skin and reduce inflammation. Might be helpful in reducing hyperpigmentation and evening out the skin tone, but evidence of effectiveness in skin are lacking~0.25–0.5%

NiacinamideUnder-dosedEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone.

What the product description says

“As well as these skin-boosting benefits, the cream features optical blurring technology, adaptive tints and light-scattering powder, so your complexion will be left looking bright, youthful and even – as well as protected.”

Source: Cultbeauty

This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.

These ingredients in the product might also be helpful for reducing and preventing fine lines, wrinkles, and skin elasticity, even though there is no conclusive evidence for their effectiveness: cyclotetrapeptide-24 aminocyclohexane carboxylate, nonapeptide-1.

It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.25–0.45%

Moisturizing

Not advertised by the brand · Nonapeptide-1, Cyclotetrapeptide-24 aminocyclohexane carboxylate + 22 more

Strong evidence

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: dextran, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, dimethiconol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: cyclotetrapeptide-24 aminocyclohexane carboxylate, nonapeptide-1

A stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C

Product summary

Based on the ingredient list, we assess that "Sarah Chapman - Skin Insurance SPF30" can provide reliable sun protection. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

Its formula is also hydrating, so you might not need an additional moistruizer during the day. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

Sunscreen filters

This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. The organic filters in the product are: avobenzone, octinoxate, octisalate, homosalate and octocrylene. As for the mineral filters, this sunscreen uses titanium dioxide.

Irritation risk

It contains a bunch of common irritants, including ingredients that do not provide any known benefit for the skin. It might not be the best choice if your skin is sensitive. We assess the overall irritancy of this product to be high. For a detailed overview of all potential irritants: click here
