Hyperpigmentation Treatment - How to Get Rid of Dark Spots | ellé derm

  

We all dream of having even, flawless skin but this is not always possible due to blotchy spots (aka hyperpigmentation) that occasionally seem to appear out of nowhere. 

 

What causes hyperpigmentation?

Hyperpigmentation can occur due to an overproduction of melanin (the pigment that gives our skin colour) in certain areas on our face (it can also occur on the body, although this is rare). Excessive sun exposure, acne and heat can cause inflammation to the skin, thus trigger our body to produce excess melanin. Post-inflammatory hyperpigmentation is extremely common amongst acne sufferers and unfortunately, people with skin of colour are most affected. 

Melasma is a type of hyperpigmentation and primarily affects the cheeks, forehead, chin and lips. This is mostly caused by changes to hormone levels and is commonly seen in pregnant women. 

 

How to Treat Hyperpigmentation

Let's talk prevention first! The #1 preventative product is sunscreen with a minimum SPF30+. Sunscreen prevents future blotchy patches from recurring so you're not undoing all the hard work you have put in to the treat the pigmentation. 

Hyperpigmentation treatment can range from hyperpigmentation creams, serums, chemical peels and laser therapy. 

 

Hydroquinone

The mainstay treatment for hyperpigmentation is Hydroquinone (HQ). Hydroquinone inhibits Tyrosinase activity and also inhibit the production of melanocytes. 

Hydroquinone is commonly used at concentrations from 2 to 4% but can be prescribed in strengths up to 10% and is available over the counter (OTC) at 2% in the United States. 

Hydroquinone monotherapy can be effective in treating post inflammatory hyperpigmentation, but more recently HQ has been formulated with other agents, such as retinoids, antioxidants, glycolic acid, sunscreens, and corticosteroids to increase it's efficacy.

Hydroquinone is an effective skin lightening ingredient but they have been known to cause ochronosis in those with darker skin during long term use and at higher concentrations. For this reason, we do recommend specialist advice if you are considering long term use.

A good over the counter product containing Hydroquinone is John Plunkett Superfade.

 

Retinoids

Retinoids exert multiple biological effects that result in skin lightening including the modulation of cell proliferation, differentiation, and cohesiveness; induction of apoptosis (cell death); and expression of anti-inflammatory properties. 

It is effective in treating hyperpigmentation, however, up to 50% of patients have reported retinoid dermatitis. 

Third-generation retinoids, adapalene and tazarotene, are synthetic topical agents that are also effective in the treatment of post-inflammatory hyperpigmentation

Isotretinoin is a naturally occurring, first-generation retinoid that is available in both oral and topical formulations. 

Retinoids are not recommended during pregnancy and a prescription is required. 

Retinol is a much weaker derivative of Retinoid and is available in many cosmetic formulations.

 

 

Niacinamide

Niacinamide has shown to be effective in the treatment of hyperpigmentation by reducing the transfer of melanin to the upper skin layers. When compared to Hydroquinone in a double-blind study, post-treatment biopsy showed Niacinamide 4% was as effective as Hydroquinone 4%, although results were seen at 8 weeks and 4 weeks respectively. 

However, Niacinamide was better tolerated and produced milder adverse effects compared to Hydroquinone. 

Examples include The Ordinary Niacinamide 10% + Zinc 1% Serum and ellé  derm Luminous Silk Brightening Serum

 

 

PW LS 9860 

This is a bioengineered complex, formulated using a synergistic blend of pea extract and sucrose dilaurate.  It is a gentle and effective alternative for patients who have reactions Hydroquinone and is also safe to use during pregnancy.

PW LS 960 lightens hyperpigmentation at the cellular level in two ways: 

  1. Inhibits the expression of gene PMEL-17 which is responsible for the maturation of melanosomes (where melanin production occurs) and 
  2. Deactivates tyrosinase activity required for melanin production.

Arbutin

Arbutin inhibits the activity of Tyrosinase to suppress melanogenesis. It acts specifically by regulating the conversion of L-tyrosine into L-dopa, and subsequent conversion of L-dopa to L-dopaquinone.

Kojic Acid

Kojic Acid blocks the production of Tyrosine which then prevents melanin from forming. Skinceuticals makes a great product with Kojic Acid and Tranexamic Acid.

L-Ascorbic Acid (Vitamin C)

Inhibits the activity of Tyrosinase and has been subject to numerous studies to demonstrate positive results for the treatment of hyperpigmentation.

The draw back with Vitamin C is that it can cause irritation in those with sensitive skin (Vitamin C requires an acidic pH to be effective) and is highly unstable when exposed to light and air (an issue when you are constantly opening and closing the bottle). A sure way to know if your Vitamin C has oxidised is when it goes from clear to brown.

Glycolic Acid & Lactic Acid

Glycolic Acid and Lactic Acid (AHAs) work as an exfoliant to remove the top layers of dead skin cells. They do this by reducing cellular cohesion between corneocytes. Over the counter topical AHAs can be used to treat hyperpigmentation but can take a long time to work, therefore we would recommend using this as maintenance therapy,  so perfect in a moisturiser. 

Higher concentrations of Glycolic Acid (40-60%) is commonly used by dermatologists and aestheticians as chemical peels for hyperpigmentation. 

At higher concentrations, Glycolic Acid has also been shown to increase collagen production.
