Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
You may know this ingredient as argan oil. Argan Oil has antioxidant, hydrating, and soothing properties.
Studies have shown argan oil can help fight again radical damage from the sun. This makes it effective at preventing hyperpigmentation.
Large amounts of vitamin E found in argan oil helps the skin retain water. Argan oil also contains fatty acids such as linoleic acid, oleic acid, and palmitic acid. It is also a good source of lipids.
Another benefit of argan oil is skin-soothing. It can help reduce inflammation-related skin symptoms.
Argan Oil is effective at regulating sebum production in pores. This can make it effective at treating hormonal acne.
Traditionally, argan oil was used for its antibacterial and antifungal properties. However, argan oil contains fatty acids that may make it not fungal-acne safe.
Argan Trees are native to Morocco.

Our bodies use biotin in the metabolism process. It also helps our bodies use enzymes and move nutrients around. A biotin deficiency can lead to brittle hair and nails.
More research is needed on applying biotin topically. However, taking biotin orally has been shown to help nourish the skin, hair, and nails. They play a role in forming skin-hydrating fatty acids.
Biotin is water-soluble. It can be found in foods such as fish, eggs, dairy, nuts, and meat. Vitamin H stands for "haar" and "haut". These are the German words for hair and skin.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.
The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.

Castor Oil helps moisturize the skin. It is rich in a fatty acid called ricinoleic acid. This fatty acid helps prevent moisture loss on the skin. This helps keep your skin soft and hydrated. Ricinoleic acid also has anti-inflammatory and pain reducing properties.
Besides hydrating the skin, castor oil is also used to hydrate hair. By keeping the hair shaft moisturized, breakage is decreased. More studies are needed to show castor oil's effective on stimulating hair growth.
Castor oil is created by cold-pressing castor seeds and then purifying the oil with heat. It was used in Ancient Egypt as fuel in lamps and to help treat eye irritation.
The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.
