Dark Spots Got Darker? The Truth About Hydroquinone Misuse
Hydroquinone is a widely used topical treatment for pigmentation issues, but it doesn’t come without risks. In fact, hydroquinone misuse is more common than most realise — especially when used for too long or layered with unsuitable skincare. This can cause irritation, damage to your skin barrier, and even worsen pigmentation.
In this article, we’ll walk you through everything you need to know about hydroquinone and the potential causes for worsening pigmentation. We’ll also cover alternative pigmentation removal treatments available in Singapore.
What Is Hydroquinone and How Does It Work?
Hydroquinone is an organic compound often classified as a topical depigmenting agent to treat various pigmentary disorders. Hydroquinone is lipophilic, which means it can penetrate the skin efficiently and has effects on a cellular level, where melanin production occurs.
It helps lighten pigmentation by inhibiting tyrosinase, an enzyme involved in the production of melanin (pigment responsible for skin colour). By blocking the activity of tyrosinase, melanin synthesis is disrupted, which, in turn, results in reduced pigment formation and fading dark spots.
Hydroquinone comes in various formulations and strengths, and can be prescribed by your doctor for the following conditions:
- Melasma
- Post-inflammatory hyperpigmentation (PIH)
- Age spots or liver spots
- Freckles
- Uneven skin tones
- Patchy pigmentation
The Dangers of Using Hydroquinone Without Professional Guidance
Although hydroquinone can be a highly effective solution for hyperpigmentation, when used for too long, can lead to serious skin complications. Hydroquinone use can also go wrong when applied in inappropriate concentrations, application methods, and even with the wrong skincare products.
Risk of Overuse and Prolonged Application
Generally, the recommended guideline for hydroquinone use is between 3 – 6 months, followed by a “rest period” to give your skin time to recover and to prevent resistance to the treatment.
When used for prolonged periods, you may experience unintended skin damage, with the skin becoming sensitive, dry and inflamed. It can also destroy the skin barrier, increasing risk of irritation, infection and rebound hyperpigmentation.
Ochronosis – A Serious Side Effect
Ochronosis is a permanent skin condition that refers to bluish-black or grey discolouration that occurs from hydroquinone overuse. It occurs deep within the dermis and is very difficult to treat or reverse, causing long-lasting and even permanent discolouration to affected areas of the skin.
Increased Sensitivity and Skin Irritation
As hydroquinone can also disrupt the skin barrier, overuse or misuse can aggravate the skin and cause inflammation, increased skin sensitivity and skin irritation.
Photosensitivity and Worsened Pigmentation
Although melanin causes pigmentation issues, it is also the skin’s natural defense against sun damage. As hydroquinone disrupts melanin production, it also makes our skin more susceptible to sun damage as less melanin is present. This can trigger photosensitivity and even worsen pigmentation in the long run.
Why Your Dark Spots Might Have Gotten Worse
If your dark spots appear to have worsened after using hydroquinone, you’re not alone. This may be caused by a series of factors. Understanding these factors can help prevent you from unintentionally worsening your pigmentation.
Rebound pigmentation: Melanin overproduction triggered by irritated skin.
Rebound pigmentation occurs when irritated skin overproduction of melanin after excessive treatment. It’s important to remember that hydroquinone is a potent active ingredient and, when overused or applied in high concentrations, can cause skin irritation. This, in turn, triggers rebound pigmentation, making dark spots more prominent instead of lighter.
Improper layering with other harsh products (retinoids, acids).
Hydroquinone should not be layered with other harsh products, such as retinoids and exfoliating acids. This can destroy and irritate the skin barrier, causing inflammation, dryness and even worsen pigmentation.
Not using SPF — leading to UV-triggered melanin production.
Not using daily sun-protection can significantly worsen your pigmentation. Hydroquinone reduces melanin in the skin, which ultimately protects you from the sun’s UV rays and makes you more vulnerable to UV damage. Without proper sun protection, the UV rays can trigger excess melanin production, causing dark spots.
Using expired or poor-quality hydroquinone products from unregulated sources.
Using expired or unregulated hydroquinone products can pose serious health risks to your skin. Expired hydroquinone may degrade or oxidise, becoming less effective or even causing irritation or unwanted allergic reactions. Unregulated hydroquinone products may contain harsh additives or incorrect concentrations that can cause skin damage.
What You Should Do Instead
When it comes to using hydroquinone to treat your pigmentation, here are some things to take note of to achieve optimal results:
- Follow the recommended duration — Hydroquinone should never be used longer than advised, as this can increase your risk of skin irritation or rare side effects like ochronosis.
- Apply only to affected areas — Apply the topical treatment only on areas with visible pigmentation. Applying it on unaffected areas of the skin may cause uneven skin lightening.
- Use sun protection — Use a broad-spectrum sunscreen SPF30 or more every day, even when indoors. Remember to reapply this every 2 hours!
- Avoid expired or unregulated products — Only use hydroquinone products prescribed by your doctor or from trusted sources. This helps prevent any risk of skin irritation or further pigmentation.
Ultimately, it’s important to pay attention to your skin. Stop using hydroquinone products if you experience any burning, redness, or worsening pigmentation. Let your doctor know so that they can modify your treatment plan.
Seek Professional Diagnosis
When using something as powerful as hydroquinone, it’s important to have your doctor’s supervision before starting treatment. They’ll be able to advise you on various formulations and help monitor your skin’s response to the treatment to avoid complications.
Furthermore, what looks like sun damage may actually be other skin conditions altogether, and your doctor can help identify the root cause of your pigmentation and recommend the right treatment plan to help you achieve your desired results.
