Hydroquinone for Dark Inner Thighs- How to Use & Risks

The gold standard for the treatment of stubborn hyperpigmentation is hydroquinone. So, it can be safely used to treat dark inner thighs as well. 

Of course, there are some initial steps I would recommend and some caution when using this treatment. But it is quite effective when used correctly. 

What Is Hydroquinone

Hydroquinone is a skin-bleaching agent that is usually used for Melasma, Chloasma, Solar lentigines, Freckles, and Post-inflammatory hyperpigmentation.

Post-inflammatory hyperpigmentation is the most common kind of hyperpigmentation and the one usually found on the inner thighs.

How Does It Work

According to science, hydroquinone works by directly inhibiting the production of melanin (pigment) in the skin. 

Specifically, it inhibits the enzymatic conversion of tyrosine to DOPA (dihydroxyphenylalanine). This results in the desired chemical reduction of melanin. Constant inhibition leads to a decrease in the number of melanocytes and decreased transfer of melanin leading to lighter skin eventually.

Side Effects Of Hydroquinone

Before we get into how to use hydroquinone, it is important to understand the possible side effects of using it. These may or may not occur, depending on how you use it and your skin’s reaction. 

The side effects may include:

  • Irritation (most common)
  • Allergic contact dermatitis
  • Redness
  • Inflammation
  • Dry skin
  • Stinging
  • Rarely ochronosis – This is a blue-black or grey-blue discoloration; it is rare and more commonly seen in people who use a high concentration of hydroquinone for a long period on large areas of the body.

Always do patch tests first. 

If you notice any of these side effects and they do not get better after 2 weeks, then you should see your doctor. You may need to change the way you use this treatment or consider alternatives.

The first step to take before using hydroquinone is to consult your dermatologist or skincare professional. 

This is the best way to determine if it is right for your skin and to develop a regimen that will work best for you. That is, by maximizing the effectiveness while minimizing the side effects. 

After or during that consult, you will be advised on how to apply it and what concentration is best for your skin.

Concentration & Formula

Hydroquinone is not approved by the FDA for OTC sale. It should only be prescribed by a doctor and the only FDA-approved Hydroquinone treatment is Tri-Luma. 

Tri-Luma cream is usually available in 0.01%, 0.05% and 4% concentrations. 

Most people generally start with the lowest concentration, but even that needs to be used cautiously. 

About 35% to 45% of hydroquinone is absorbed systemically after topical use so keep this in mind if you have super sensitive skin.

Your doctor will look at your skin and decide what concentration you should start with. 

Always patch-test your skin first.

How To Apply

  1. Hydroquinone is to be applied on your skin only (topically). 
  1. A thin layer is applied onto clean skin. If you have sensitive skin, you can apply it over a simple moisturizer or hyaluronic acid serum. But avoid moisturizers that have acids, active, or irritating ingredients. These can cause irritation when used with hydroquinone.  Click here to read all about How to Moisturize with Hydroquinone & The Best Ones To Use
  1. To see results, you will need to apply it 1 to 2 times a day for 3 to 6 months. If you do not see results in 6 months, then you should stop using hydroquinone and consider different alternatives.
  1. Many studies show that using hydroquinone as a combination therapy with a retinoid and corticosteroid can have better results. Many experts also advise their patients to use these combinations. However, this needs to be guided by a professional and used on a prescription basis.
  1. When using hydroquinone, you will also need to use a good, broad-spectrum SPF. You will need to protect your skin from the sun at all times. This is especially important if you are wearing shorts or going to the beach or out of the house a lot. 

How long will hydroquinone take to work?

You should start seeing results within two weeks of consistent Hydroquinone use. However, this can take up to 4-6 weeks depending on how bad your hyperpigmentation is. 

If you do not see any results at all within 3-6 months, then you should not continue the treatment. 

Results will vary for every individual.
