Squalane Vs. Squalene: What’s The Difference And Why Should You Care?

Written by Ramona Sinha

Given the significant role hydration plays in skin care, it is not surprising that we come to learn of new hydrating ingredients regularly. If you love to delve deep into emerging skin care practices, you might have heard of these two similar-sounding ingredients making the rounds as super skin hydrators: squalene and squalane.

What exactly are these, how are they different, and how to use them in skin care? Let us find out.

Squalane Vs. Squalene: What Is The Difference?

Both squalene and squalane are naturally occurring substances found in certain animal fats and plant oils. They are similar from a chemical perspective and are known for their highly effective emollient properties.

While both are known to have antioxidant properties and are used as moisturizers, here are a few differences between the two:

1. What Are They?

Squalene is a polyunsaturated hydrocarbon and a colorless liquid with a faint odor. It is naturally found in fish oils, especially shark liver oil, and in high amounts in some plant fats.  Our body naturally produces squalene. The human sebum contains 13% squalene and is ubiquitously distributed in human tissue to keep our skin hydrated and maintain the natural barrier.

Squalene is not stable in its natural form. That is why it is saturated to create squalane. In other words, squalane is the saturated and stable form of squalene.

As we age, the natural squalene production in our body declines, and our skin becomes dry, rough, and dehydrated. That is when we need squalane added to skin care products and serums.

2. How Squalene Is Derived?

The greatest concentration of squalene is found in shark liver that dwells at a depth of 400 m. The liver of Centrophorus squamosus or the leafscale gulper shark is composed of 77.2% oil, and the squalene concentration of this oil is 79.6%. Other organs of sharks also contain some amount of squalene.

Hence, the squalane in all skin care products is (unfortunately) derived from squalene obtained from sharks.

3. Shelf Life

Squalene is not stable in its natural form. It is saturated to form squalane, which is stable and has a longer shelf life.

4. Best Suited For

Products with squalene or squalane are better suited for dry and mature skin, though it can benefits all skin types, including sensitive skin. Since squalane hydrates the skin and prevents transepidermal water loss (TEWL), people with problematic skin and issues like eczema, acne, and rosacea may also benefit from the ingredient.

What exactly do these ingredients do that makes them so popular in skin care?

What Does Squalene Or Squalane Do To Your Skin?

Both squalene and squalane work great as moisturizers and emollients. They help repair damaged skin and rejuvenate skin by preventing transepidermal water loss and trap moisture to hydrate your skin. They also prevent free radical damage and oxidative stress, which are primary reasons for premature aging and wrinkles. With regular usage, they can smooth out fine lines, fade scars, and minimize UV damage.

Other than hydration and emollient benefits, squalane (or squalene) can keep your skin healthy in multiple ways.

How Does Your Skin Benefit From Squalene Or Squalane?

1. Antioxidant Effects

Both squalane and squalene are potent antioxidants. They can combat free radical damage, minimize signs of aging and photodamage and help maintain overall skin health. They can also alleviate skin irritation.

2. Anti-Inflammatory Benefits

Squalene (derived from virgin olive oil) has anti-inflammatory properties and can help reduce redness and swelling associated with skin inflammation and promote wound healing.

Using products with squalane can offer some great benefits to your skin. However, if you have problematic skin, it is better to consult a doctor before using any product. This is because the product may contain a mix of ingredients other than squalane and may trigger allergic reactions.

Who Should Use Squalane?

Anyone who wants soft, supple, hydrated, and glowing skin should consider using squalane or squalene. It is gentle enough for those with sensitive or acne-prone skin due to its anti-inflammatory properties. It is non-comedogenic and good for those struggling with skin issues, such as psoriasis or eczema.

Squalane is found in multiple skin care products. Here are a few ways to incorporate it into your daily skin care routine.

What Is The Best Way To Use Squalane?

1. As A Serum

Squalane oil can be used as a serum in your regular beauty routine. Just dab on a few drops of squalane-enriched face oil in place of your regular serum.

2. For Makeup Removal

You may find squalane in cleansing oils and balms and use them to remove makeup and dirt from your face without stripping the natural oils.

3. Add A Few Drops To Your Moisturizer

Make your regular moisturizer more efficient by adding a few drops of squalane oil to it.

4. Use Products Enriched With Squalane

You can buy eye creams, serums, moisturizers, lotions, and facial oils enriched with squalane.

While squalane can indeed give your skin a dewy, smooth, and youthful look, you have to ensure you are using it in the optimal way.

How To Get The Best Results With Squalane?

If you are a beginner, use squalane regularly. Make it an inherent part of both your morning and evening routines. Always apply squalane to freshly cleansed skin for the best results.

If you have dry skin, you can pair squalane with hyaluronic acid for intense hydration.

While squalane is a useful and versatile ingredient, is it suitable for everyone?

Who Should Avoid Using Squalane?

Squalane is safe for all skin types as it mimics the natural oils. However, if you are allergic to it, squalane may cause:

  • Redness
  • Irritation
  • Itching
  • Swelling

Always do a patch test to avoid allergic reactions.

Moreover, harvesting squalane is not an environmentally safe and sustainable practice as it is mainly derived from sharks. Therefore, you can check for products that contain plant-derived squalane.

In Closing

Squalane is a natural ingredient that hydrates your skin, repairs damage, and soothes redness and irritation. If you have dry and mature skin and are looking for an ingredient for hydration, you can rely on squalane. However, if you are concerned about its environmental impact, buy pure plant-based squalane oils or products that contain plant-derived squalane.
