Ever wondered what gives your favorite skincare products their luxurious feel? Dive into our latest article, "Shark Lipids: An In-Depth Look at Its Role in Cosmetics," and discover the fascinating journey of shark lipids from ocean depths to beauty shelves, along with their benefits and potential side effects.

What Is Shark Lipids?

Shark Lipids, derived from the tissue of the blue shark (Prionace glauca), are a unique ingredient in the world of cosmetics. This ingredient is primarily known for its skin conditioning properties. Chemically, these lipids are rich in squalene, a natural organic compound that is also found in human sebum, making it highly compatible with our skin.

The use of shark lipids in cosmetics has an interesting history. Traditionally, squalene was sourced from shark liver oil and has been used for centuries in various cultures for its purported health benefits. However, it wasn’t until the early 20th century that the cosmetic industry began to recognize its potential. The moisturizing and emollient properties of squalene made it a sought-after ingredient in skincare formulations, leading to its incorporation in a variety of products, from creams to serums.

The production of shark lipids involves extracting the oil from the liver of the blue shark. This oil is then refined and purified to isolate the squalene, which is subsequently hydrogenated to produce squalane, a more stable form that is less prone to oxidation. This process ensures that the final product is both effective and safe for use in cosmetics.

The Benefits/Uses of Shark Lipids

In this section, we will delve into the officially recognized cosmetic benefits and uses of Shark Lipids:

Skin Conditioning

Shark Lipids are primarily known for their skin conditioning properties. This means that when applied to the skin, they help to maintain the skin’s softness, suppleness, and overall health. The lipids work by forming a barrier on the skin’s surface, which helps to lock in moisture and prevent dryness. This can be particularly beneficial for individuals with dry or sensitive skin, as it helps to keep the skin hydrated and comfortable.

Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Shark Lipids, like many cosmetic ingredients, come with their own set of considerations regarding safety, suitability, and allergenic potential. While generally considered safe for topical application, there are potential side effects that users should be aware of:

  • Skin irritation
  • Redness
  • Allergic reactions
  • Contact dermatitis

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Shark Lipids during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.

Adverse reactions to Shark Lipids are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to perform a patch test before widespread usage.

On the comedogenicity scale, Shark Lipids are generally rated around a 2, meaning they have a low to moderate potential to clog pores. This is an important consideration for individuals who are prone to acne, blemishes, or breakouts, as using products with a higher comedogenic rating can exacerbate these conditions.
