What is Glutathione & What Are its Beauty Benefits?

Before we get started, let’s quickly discuss exactly what glutathione is, along with its main skincare benefits.

Glutathione is a strong antioxidant that’s naturally produced by our bodies.

It’s made up of three amino acids and is used for a number of biological processes, to the point where several diseases, including metabolic disorders, asthma, and cancer, have been associated with low glutathione levels [1].

This is why glutathione therapy is commonly utilized in the medical field.

When it comes to the skin, glutathione is a powerful skin lightening agent. It works by inhibiting the tyrosinase enzyme.

This enzyme triggers melanin production, which is the pigment that gives your skin its color, as well as its discoloration. Due to its tyrosinase inhibition, glutathione is able to bring about a lighter skin tone.

However, that’s not all. Being an antioxidant means that glutathione also offers up important anti-aging benefits. By increasing the levels of glutathione in your body, you’ll also be stimulating collagen and elastin production.

The result? A big improvement in skin elasticity, meaning smoother, firmer, and tighter skin.

There are a number of studies out there that have confirmed the general skin lightening effect that glutathione has [2]. This research also backs up the ingredient’s anti-aging benefits.

The before & after photos that we viewed completely support this – everything from acne marks to melasma becomes less noticeable after regular use of glutathione. You’ll see some amazing testimonials on social media!

That said, the research also shows that dosage greatly influences how effective glutathione is, making it important to get this right if you want to see solid results.

The oral administration of glutathione pills is one of the most popular ways to take the ingredient. The recommended dosage is 20-40mg of glutathione per kg of body weight. This should be taken daily, either in one go or split into two doses.

How long you take glutathione for depends on your skin colour. Those with light-medium brown skin will see results after 1-3 months. If you have dark brown skin, you’ll need to take it for 3-6 months.

Those of you with very dark skin/ black skin may need to take it for up to 12 months before the skin lightening works.

Combining glutathione supplementation with other oral antioxidants, particularly vitamin C, has been proven to help the ingredient work to a greater extent.

Topical Glutathione & Vitamin C Products to Reduce Melanin Production and Clear Hyperpigmentation

A topical glutathione solution, either in the form of a serum or a cream, is often the best way to treat your skin. With this method, the antioxidant is directly absorbed into the skin, rather than having to first deal with the harsh conditions of your digestive system.

Dosage is easy – simply look for a product that lists glutathione near the top of its ingredient list. Again, combining it with ascorbic acid, as well as vitamin E, will bring you better results.

A glutathione injection usually provides a higher dose than oral glutathione supplements. This could range between 600-1200mg, depending on what your doctor advises.

You’ll need to take 1-3 injections a week.

Is Glutathione Safe? Information on Safety Levels & Side Effects

When it comes to intravenous glutathione, there have been a few significant adverse effects reported. However, these have all been related to issues with other ingredients in the injection. When pure glutathione is used, side effects are very rare.

In terms of oral supplements, there isn’t much information out there related to side effects. Long-term usage has been linked to lowered zinc levels, which is why you should only take glutathione for a few months at a time. If you’re concerned, speak to your doctor before taking oral glutathione.
