Do Mikorogo Cause Body Odour? Dermatologist Explains the Truth Behind the Smell

Popular skin-lightening mixtures, known locally as mikorogo, carry severe chemical risks that go far beyond surface-level side effects or body odour concerns, a leading dermatologist has warned.

Dr Pauline Gacheri, a dermatologist at the Meru Teaching and Referral Hospital, cautioned that chemical damage caused by uncertified creams can permanently impair skin health, delay surgical recovery, and lead to systemic organ damage.

Her warning comes amid widespread public speculation linking skin bleaching directly to distinct body odours, particularly when users are exposed to sunlight.

Addressing the claims, Dr Gacheri clarified that skin bleaching itself does not scientifically cause body odour. Instead, the distinct smells reported by some users usually stem from the heavy added fragrances within the product mixtures themselves.

She added that these cosmetic fragrances often react with pre-existing body conditions. When mixed with natural sweat in individuals suffering from excessive sweating (hyperhidrosis) or strong body odour (bromhidrosis), the combination can create a noticeably altered smell.

She noted that while high concentrations of hydroquinone may potentially slow down the body's breakdown of trimethylamine, a compound that causes a fish-like odour when released through sweat or urine, this theoretical connection does not mean bleaching directly creates body odour.

Instead, Dr Gacheri urged the public to focus on the far more dangerous chemical ingredients hidden inside many over-the-counter preparations.

Many uncertified mixtures contain hazardous levels of hydroquinone, corticosteroids, and concealed mercury compounds. While hydroquinone is restricted to a maximum permissible concentration of 4 per cent, some unregulated preparations on the market contain dangerous levels ranging from 15 to 20 per cent, or higher.

Prolonged exposure to high doses of hydroquinone can trigger exogenous ochronosis, a permanent condition that causes blue-black discolouration of the skin. Patients often mistake this condition for melasma, leading them to apply even more bleaching creams and worsening the damage.

The inclusion of potent corticosteroids presents equally severe physical risks. Steroids inhibit skin cell proliferation, reducing both the outer and inner layers of the skin while breaking down essential collagen and dermal structures.

This structural breakdown leaves the skin thin, fragile, and prone to severe stretch marks on the thighs, breasts, and buttocks. It also creates major complications for routine cosmetic and medical procedures.

Women with bleached skin frequently suffer severe bleeding and skin tearing during basic hair removal procedures such as waxing on the underarms, legs, and bikini area.

"The effects can complicate recovery from injuries and medical procedures," Dr Gacheri explained, noting that steroids suppress the skin's natural immune response. "Even after surgery, recovery may take longer than it would for someone with healthy skin because the structure of the skin is already messed up."

Furthermore, toxic mercury compounds concealed in these mixtures pose silent systemic threats. Mercury exposure can cause severe damage to the kidneys and lungs. Medical professionals have even detected mercury in the placentas of women during childbirth, raising grave health concerns for pregnant women and those planning to conceive.

Dr Gacheri advised anyone experiencing adverse reactions to immediately stop using all uncertified lightening creams. She emphasised that medical specialists must focus on restoring basic skin integrity and treating underlying fungal infections, rashes, or extreme dryness before attempting any further dermatological treatments.
