This week, Anvisa announced the suspension of the sale and use of hormonal implants known as “beauty chips”. The decision affects products manufactured in pharmacies, prohibiting their sale, advertising and use.
These implants, which are applied under the skin and contain one or more hormones, are widely used for aesthetic purposes and to treat symptoms such as fatigue and menopause. However, Anvisa has warned that these products are not registered, and there are no guarantees of quality, safety and effectiveness. Associated risks include high cholesterol, hypertension, stroke and arrhythmias.
What are “beauty chips”?
So-called “beauty chips” are subcutaneous hormonal implants, similar to the size of a matchstick, that release hormones into the body continuously. They are often used to promote weight loss, muscle gain and control hormonal symptoms, such as those associated with menopause.
How do they work?
Hormonal implants work by releasing hormones into the bloodstream at a constant rate. These hormones, which include estradiol, progesterone, and testosterone, are commonly administered orally or transdermally.
According to Dr. Alexandre Silva e Silva, the hormonal delivery of manipulated implants differs from traditional methods:
“When we place a subcutaneous hormonal implant, the body identifies it as a foreign body and begins a defense process. The body creates new vascularization around the implant, allowing blood to come into direct contact with it, releasing small amounts of hormones into the bloodstream with each heartbeat,” he explains.
This continuous release is what ensures the prolonged effect of the implant, but it can also present challenges in terms of safety and efficacy.
What do experts say about implants?
Although there are benefits associated with hormone therapy, such as reduced cardiovascular risk and a lower likelihood of developing osteoporosis, not all women can use them.
“Patients with a history of breast cancer, for example, cannot undergo hormone replacement therapy due to the increased risk of disease recurrence. Furthermore, there are no robust scientific studies that prove the safety and efficacy of manipulated hormonal implants,” says Dr. Alexandre Silva e Silva.
He also warns against inappropriate use: “If used incorrectly, especially in overdoses, aiming for rapid aesthetic effects, implants can cause numerous side effects and harm users.”
Reflection and next steps
The suspension of hormonal implants by Anvisa highlights the need for more in-depth studies on this technology. “The moment calls for reflection and the conducting of scientific studies that can definitively answer questions about the safety and efficacy of this method. Medical practice must always be based on scientific evidence to ensure patient safety,” concludes Dr. Alexandre Silva e Silva.
