Glycolic acid is an alpha hydroxy acid (AHA) derived from natural sources. It’s prized in skincare for its ability to exfoliate the skin, promoting cell turnover and revealing a brighter complexion. Its small molecular size allows for deeper penetration compared to other AHAs.

Historically, this ingredient was first extracted from sugarcane. Today, it’s also commercially produced from sources like pineapple, unripe grapes, and beetroot. Regardless of the source, the resulting glycolic acid possesses the same potent exfoliating properties.

Glycolic acid offers a multitude of benefits, and is a key ingredient in how to get rid of hyperpigmentation:

• Exfoliates dead skin cells, revealing a brighter skin.

• Stimulates collagen production, improving skin firmness.

• Unclogs pores, reducing breakouts.

• Fades skin pigmentation, evening skin tone.

It’s a versatile ingredient suitable for a range of skin concerns. If your skin concerns persist or worsen, it’s always best to consult a dermatologist for personalized advice.

Hyperpigmentation isn’t a surface-level issue; it’s a response within the skin’s melanocytes – the cells responsible for producing melanin. When these cells are triggered by factors like UV exposure, inflammation, or hormonal shifts, they produce an excess of melanin. This surplus isn’t distributed evenly, resulting in concentrated areas of darker pigmentation.

The skin’s natural process of shedding dead cells usually regulates melanin levels, but when this process is disrupted, or melanin production is excessively stimulated, hyperpigmentation becomes visible. It’s a complex biological response, not simply a cosmetic flaw.

This ingredient's efficacy in addressing hyperpigmentation hinges on proper application. It’s not a one-size-fits-all solution; understanding your skin type and the specific type of hyperpigmentation is crucial.

The approach varies depending on the cause. Sunspots respond well to consistent, moderate-strength glycolic acid use, gradually fading their appearance. PIH often requires a gentler approach, as the skin is already sensitive. Melasma is notoriously stubborn and may require professional-strength peels under dermatological supervision. Post-inflammatory hyperpigmentation benefits from a cautious, gradual introduction of this AHA, allowing the skin to heal while minimizing further irritation.

When incorporating this ingredient into your routine, consider products with varying concentrations. A lower concentration, suitable for daily use, can help maintain a consistent level of exfoliation. Products with a higher concentration, intended for less frequent use, provide a more intensive treatment. For example, a daily glycolic acid essence allows for gentle, continuous exfoliation, while a peel mask to apply twice a week delivers a more potent dose.

Regardless of the chosen concentration, always follow with a broad-spectrum SPF 30 or higher, as glycolic acid increases sun sensitivity. Patience is paramount; visible results typically take several weeks of consistent use.

Glycolic acid is a key ingredient for treating hyperpigmentation, as it gently exfoliates the skin and promotes cell turnover. When combined with niacinamide for dark spot reduction, it helps fade discoloration more effectively and restores a brighter, more even complexion.
