Are There Side Effects of Medical Aesthetic Applications? Safe Beauty Guide
Today, medical aesthetic applications have become an indispensable choice for millions of people who want to rejuvenate and beautify without the need for surgery. The "before-and-after" photos, smooth skin and perfect lips we see on social media can create the perception that these procedures are like a touch of a magic wand and carry no risk.
Are There Side Effects of Medical Aesthetic Applications?
"Is it necessary to take risks "for the sake of beauty"? Realistic Expectations
Medical aesthetic procedures are extremely safe when performed in the right hands, with the right products and under sterile conditions. However, saying “there are no side effects” is against medical ethics. Our body is a living organism and reacts to every external intervention (needle, heat, foreign substance). These reactions are usually temporary and a natural part of the healing process. It is important that this process is managed under the supervision of a physician.
The Critical Difference Between Side Effect and Complication
It is necessary to distinguish between two concepts that patients most often confuse:
- Side Effect (Expected Condition): These are conditions that may occur due to the nature of the procedure, are temporary and usually resolve spontaneously. For example; swelling after lip filling, redness at the injection site after botox. These are normal parts of the process.
- Complication (Undesirable Situation): A malpractice is an undesirable condition resulting from a product defect or a patient's physiological response that requires medical intervention. For example, infection, asymmetry or tissue loss.
Our aim is to minimize side effects and reduce the risk of complications to zero.
Possible Side Effects of Injectable Procedures (Botox and Fillers)
Botox and fillers, which are the most common procedures, have some common side effects because they are performed with a needle.
After Botox Headache and Temporary Asymmetry
Botox The most common side effects after the injections are small bruises at the injection points and mild headache. Headache usually occurs within the first 24-48 hours after the drug starts to relax the muscles and is relieved with simple painkillers. A rarer condition is “Ptosis” or droopy eyelid. This occurs as a result of the drug accidentally spreading to the neighboring muscle and is temporary. Even in preventive Botox applications, an unusual “feeling of heaviness” may be experienced in the first days as the muscle structure changes.
Dermal Fillers: Edema, Bruising and Rare Risks
Dermal fillers applications, volumizing procedures, the body's response may be more pronounced.
- Edema (swelling): Hyaluronic acid is a water retaining substance. In the first 3 days after the procedure, it is very normal for the area to look more swollen than it is.
- Clumping In the first weeks, the filling may feel hard in the hand, it improves with massage or over time.
- The Tyndall Effect: Superficial fillers under the eye appear bluish from the outside.
The Most Feared Scenario: Vascular Occlusion
This is not a side effect but a serious complication. It is the stoppage of blood flow as a result of the filler being accidentally introduced into the vein or pressing on the vein. It manifests itself with whitening of the skin and severe pain. However, the biggest advantage of hyaluronic acid fillers, Hyaluronidase enzyme to dissolve the filler. This enzyme dissolves the filling instantly, opening the vessel and saving the tissue. Therefore, filling procedures must be performed by physicians who can manage this complication.
Side Effects of Skin Resurfacing and Energy Based Devices
Lasers and radiofrequency devices work by causing controlled damage to the skin.
After Laser and Gold Needle: Redness and Crusting
Golden Needle (Scarlet X) or fractional lasers, a redness and heat sensation similar to sunburn occurs on the skin, followed by micro crusting. This is not a side effect but a sign that the healing mechanism has started. It usually passes within 3-5 days.
Post-Inflammatory Hyperpigmentation (Spot Formation)
Especially in dark-skinned people, redness after laser or peeling may turn into brown spots (PIH) if exposed to the sun. To prevent this risk, it is essential to use high-factor sunscreen after the procedure.
Reactions seen in Skin Care and Peeling Procedures
Procedures to clean and peel the skin may also cause a reaction, even if they seem innocent.
"Purging" (vomiting) Period: Increase in Acne
Hydrafacial or after chemical peels, some patients may experience a sudden increase in acne. This is called “purging”. It is when blockages under the skin quickly come to the surface. This is not a bad thing; on the contrary, it indicates that the skin has been deeply cleansed and is temporary.
Patient Responsibilities to Minimize Side Effects
A safe aesthetic process requires the cooperation of the patient and the doctor.
Pre-Procedure Preparation: Blood Thinners and Alcohol
İşlemden en az 3 gün önce Aspirin, E vitamini, Ginseng, Yeşil Çay ve alkol tüketimini kesmek, morluk ve kanama riskini %50 oranında azaltır. Morluk oluşursa da iyileşme süresini kısaltır.
Post Procedure Hygiene: Infection Prevention
Avoid touching the injection points with water, make-up and dirty hands for the first 24 hours to prevent the risk of infection. About the safety of cosmetic procedures American Food and Drug Administration (FDA) also emphasizes the importance of hygiene and the selection of competent practitioners.
