This product offers a good level of protection against both UVB and UVA rays.

This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

OctocryleneUVB Photo-stable A weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen~4.4–5.4%

What the product description says

“An alternative approach to sun protection, this light textured, moisturising SPF45 serum is built to protect against UVA/UVB and Infrared rays.”

Source: Boots

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: carnosine, 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, jojoba esters.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

Jojoba estersKey active· EmollientEffect: HighAn emollient made of jojoba oil. Helps soften the skin and support its barrier function~0.55–0.85%

PantolactoneKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.1–0.15%

Polyglycerin-3Key active· HumectantEffect: HighHelps to attract water to the upper layer of the skin~0.1–0.2%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.2–0.35%

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.65–0.95%

CarnosineKey active· HumectantEffect: HighA type of peptide. It attracts water to the upper layer of the skin. It can help neutralize free radicals in skin combatting the sun damage~0.25–0.4%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2.1–2.5%

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.5–1.8%

Dicaprylyl carbonate· EmollientEffect: LowHelps products spread more easily and works as an emollient to soften skin~0.95–1.15%

Aloe barbadensis leaf juice powderEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.15–0.3%

GluconolactoneUnder-dosedEffect: HighA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.2–0.4%

AllantoinUnder-dosedEffect: HighHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.25–0.5%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.25–0.45%

Anti-oxidation

Not advertised by the brand · 4 ingredients credited for this claim

Strong support

This product contains antioxidants (carnosine) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Sodium ascorbyl phosphateUnder-dosedEffect: MediumA 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~0.2–0.35%

GluconolactoneUnder-dosedEffect: MediumA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs.

Strong support

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).

Anti-aging

Not advertised by the brand · 4 ingredients credited for this claim

Strong support

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: carnosine.

CarnosineKey activeEffect: MediumA type of peptide. It attracts water to the upper layer of the skin. It can help neutralize free radicals in skin combatting the sun damage~0.25–0.4%

Product summary

Based on the ingredient list, we assess that "Hello Sunday - The One That's A Serum Face Sunscreen SPF 45" 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).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. Here are the exact UV filters in this sunscreen: tinosorb s 3.00% - 3.70%, avobenzone 3.50% - 4.30%, butyloctyl salicylate 6.80% - 8.30%, uvinul t 2.10% - 2.60%, octocrylene 4.40% - 5.40% and ensulizole 1.70% - 2.00%.

Irritation risk

This product does not contain known common irritants and is suitable for sensitive skin. We assess the overall irritancy of this product to be low. For a detailed overview of all potential irritants: click here
