These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Zinc Oxide is a mineral broad-spectrum UV filter; it is the broadest UVA and UVB reflector approved by the FDA. While it is most commonly man-made for cosmetics, it can naturally occur in zincite, a rare mineral.
Today, traditional and nano-sized zinc oxide can be found in beauty products. Nano-sized zinc oxide can enhance a product's UV protection. While it is not believed to have a negative effect on skin, nano-zinc oxide may be harmful to coral reefs - though the verdict is not entirely out on this one.
Zinc Oxide also has antibacterial and calming properties. It is not water soluble.
Zinc has been used throughout history as an ingredient in paint and medicine. An Indian text from 500BC is believed to list zinc oxide as a salve for open wound. The Ancient Greek physician Dioscorides has also mentioned the use of zinc as an ointment in 1AD.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.

This ingredient is an emollient and emulsifier. As an emollient, it helps soften skin by trapping moisture within. As an emulsifier, it prevents oil and water ingredients from separating.

The absolute best sunscreen I've ever tried!!! Works amazing for my crazy sensitive dry skin. However, packaging is horrible which spills easily. Would still repurchase because it works so well but I really wish the brand would improve the packaging.
this is literally the best facial sunscreen i have ever used. it applies so smooth & leaves a gorgeous glow on the skin. i know the bottle is really small but it somehow lasts forever?? i just wish it wasn’t so damn expensive otherwise i have zero complaints.
Kopari Bright As Day Sheer Mineral Sunscreen SPF 50 36 ingredients
Pros: nice tone for my skin (slightly peach/ yellow colour), blends in very well and leaves slight glow, has niacinamide and astaxanthin.
Cons: feels slightly gritty when applying (feels smooth after rubbing), has slightly glittery finish, contains chemical spf booster so wrongly marketed at 100% mineral, has silicone.
Overall a great option if I want some extra coverage or even out my skin Show more
