Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Some studies have shown this ingredient can promote wound healing with higher concentrations.
Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.

Aloe is one of the most well-known natural soothing ingredients, and for good reason. It’s full of water and has a cooling, calming effect on the skin, especially when it’s sunburned, itchy, or irritated. Aloe also helps your skin stay hydrated and smooth by mimicking what healthy skin naturally produces. On top of that, it contains vitamins and nutrients that support skin recovery.Â
It doesn’t protect you from the sun, but it can help your skin bounce back after too much time in it.
Let’s get into the details:
Aloe contains antioxidant Vitamins A, C, and E, which help fight off free radicals (unstable molecules from things like pollution that can damage your skin).
It’s also rich in polysaccharides, which are natural sugars that help hydrate the skin by acting like the skin’s own moisturizing agents. These, along with other sugars like monosaccharides, help form a protective barrier that locks in moisture.
Aloe works as both a humectant and an emollient. That means it draws water into the skin (humectant) and helps trap it there (emollient), making it an effective natural moisturizer.
You’ll also find a mix of other skin-supporting ingredients in aloe, including folic acid, choline, calcium, amino acids, fatty acids, and even Vitamin B12.
Out of the 420+ species of aloe, Aloe barbadensis is the most widely used in skincare products thanks to its gentle yet effective properties.
There are over 420 species of aloe but Aloe Barbadensis is the most commonly used for topical products.
