Product Summary
Based on the ingredient list, we assess that "Bliss - Block Star Sheer spf 50" can provide reliable sun protection. We love that it can protect from both UVA and UVB rays (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 product is a mineral sunscreen. It uses zinc oxide for sun protection. Zinc oxide almost never irritates the skin or stings eyes, but it can leave a white cast.
Irritation risk
This product does not contain known common irritants and is suitable for sensitive skin. We assess the overall irritancy of this sunscreen to be low. For a detailed overview of all potential irritants: click here

Anti-aging
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.
A 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
Evens skin tone
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).

Sun protection
This product offers a good level of protection against both UVB and UVA rays.
It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.
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.
A broad spectrum sunblock (protects from both UVA and UVB rays). Is suitable for most sensitive skins. In small concentrations, can be used as a colorant
Moisturizing
What does the product description say?
This potent, yet lightweight moisturizer absorbs instantly to replenish and deliver lasting hydration for healthy, soft skin with a vibrant glow.

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:
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: caprylic/capric triglyceride, dimethicone.
A great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function

A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
