From recovery period to precautions

Intensive initial reactions within 48 hours
Average recovery 3-5 days
Side effect rate 8-12%

48 hours after the procedure, these symptoms are normal

The most frequently asked question in the clinic is 'Is this a side effect?' In reality, in most cases, it is a normal reaction.

Aquafilling is a polyacrylamide hydrogel (PAAG) type filler; when injected into the dermis, a temporary inflammatory response occurs during the tissue regeneration process. This is a normal immune response that stimulates collagen synthesis. **Edema** is observed in over 90% of injection sites between immediately after the procedure and 48 hours later. Based on an injection depth of 1.5–2 mm, it lasts for an average of 48–72 hours and is relieved by cold compresses. **Erythema** appears as capillaries dilate due to irritation from the injection needle and decreases by 80% within 24 hours. If redness persists for more than 3 days, the possibility of inflammation should be checked. **Ecchymosis** occurs in 10–15% of areas with high vascular density (around the eyes and cheeks) and typically disappears naturally within 5–7 days. The incidence rate doubles when taking aspirin or ginkgo leaf extract. Key Points Swelling, redness, and bruising normally peak within 48 hours and then decrease. If symptoms worsen or new ones appear after 3 days, consultation with a specialist is required.

Unlike normal reactions, the following symptoms may be a sign of tissue damage or infection.

**1. Asymmetrical Deformation**: If the area is symmetrical immediately after injection but one side swells more after 48 hours, suspect a difference in absorption rates or local inflammation. Re-correction may be necessary.

**2. Hard Nodule**: A hard lump palpable with a diameter of 3mm or more indicates over-injection or an aggregation reaction. Domestic reports indicate a nodule incidence rate of 2-4% after Aqua Peel procedures.

**3. Heat/Tenderness**: If the treatment site feels hot and causes severe pain upon pressing, there is a possibility of bacterial infection (cellulitis). Antibiotics must be administered within 72 hours.

**4. **Skin discoloration**: If the skin turns pale or dark red, it is a sign of vascular occlusion or necrosis. Immediate hyaluronidase dissolution or surgical intervention is required. **5. Migration**: If it deviates more than 1 cm from the injection site, it is caused by failure of injection into the fascial layer or an overdose. FDA-approved products (such as Aquamid) have a migration rate of less than 1%, while non-approved products are reported to have a rate of 5% or higher. **6. Persistent severe edema**: If swelling does not subside after 72 hours, check for lymphatic circulation disorders or allergic reactions. **7. Dyspnea/Hives**: Systemic allergic reactions (anaphylaxis) occur in less than 0.01% of cases, but if they occur, emergency administration of epinephrine is required. **Caution**: If any of the above symptoms apply, contact the hospital where the procedure was performed within 24 hours. Early intervention prevents permanent damage.

Recovery Stage Timeline: Day 0 - Week 4

Aqua Peel recovery is largely It is divided into three stages. Management methods differ for each stage. **0-3 days (Acute Inflammatory Phase)**: Tissue damage repair is concentrated immediately after injection. Swelling peaks 24-48 hours later and decreases by 20-30% per day thereafter. Cold compresses are recommended for 10 minutes per session, 4-6 times a day. Direct contact with ice poses a risk of frostbite, so it must be wrapped in gauze. **4-7 days (Recovery Phase)**: Epidermal regeneration begins, and more than 70% of the swelling subsides. Bruising turns yellow and disappears between days 5 and 7. Light cleansing and makeup are possible from this period, but direct rubbing of the injection site is prohibited. **8-28 days (Stabilization Phase)**: Collagen remodeling proceeds, and the final contour is established. The 2021 guidelines of the Korean Dermatological Association recommend re-evaluation after 3-4 weeks. If asymmetry is present at this point, consider a corrective procedure. Return to work is generally possible on days 3-5, but if you have a lot of face-to-face work, it is safer to allow 5-7 days. It takes an average of 10-14 days for the swelling to completely subside. Tip: Recovery speed varies depending on the individual's immune status and the dosage of the injection. Find a hospital with systematic recovery care at K-Dia.

Peak swelling 24-48 hours
70% swelling gone 4-7 days
Complete bruising gone 5-7 days
Final contour stabilization 3-4 weeks

5 Things You Absolutely Must Not Do

Failure to observe contraindications during the recovery period increases the incidence of side effects by more than 30%.

**1. Exposure to High Temperatures**: Saunas, steam rooms, and hot springs worsen swelling due to vasodilation. As a general rule, they should be avoided for 2 weeks after the procedure, and hot showers (above 40°C) should also be avoided for 7 days.

**2. Alcohol Consumption**: Alcohol promotes blood circulation, increasing bruising and swelling by 2-3 times. Abstinence from alcohol is recommended for at least 72 hours, and preferably for 1 week.

**3. Vigorous Exercise**: Exercise that increases heart rate by more than 30% compared to normal (running, weight training) raises blood pressure and increases the risk of bleeding. Light walks are possible after 48 hours, but full-scale exercise should be resumed after 7 days.

**4. Smoking**: Nicotine delays tissue recovery due to vasoconstriction. Smoking cessation is required for a total of 4 days, 48 hours before and after the procedure. **5. Compression and Massage at the Injection Site**: External pressure causes displacement until the Aqua Peel settles into the fascial layer. You should also avoid pressing your face with a pillow for 2 weeks after the procedure. **20s vs. 40s: Why Recovery Speeds Differ** **Tissue Regeneration Speed and Side Effect Patterns Differ by Age Group.** **20s**: Collagen synthesis is rapid and lymphatic circulation is active, so swelling decreases by more than 70% within 3-4 days. However, the inflammatory response is also strong, so initial erythema may appear more distinctly. **30s**: The average recovery period is 5-7 days, which is not significantly different from the 20s, but the duration of bruising is 1-2 days longer. From this period onwards, consuming antioxidants (Vitamin C 1000mg/day) helps with recovery. **40s and older**: Bruising may persist for 10 to 14 days due to reduced dermal thickness and decreased vascular elasticity. Domestic clinical studies report that the incidence of nodules in people in their 40s is 1.5 times higher than in those in their 20s. Taking vascular strengthening agents (rutin or hesperidin) before the procedure is recommended. Post-menopausal women experience slower wound healing due to decreased estrogen, extending the average recovery period to 7 to 10 days. In this case, supplementing with collagen peptides (5g/day) is helpful. Clinical Personalized management considering age-specific differences is key to reducing side effects.

3 Management Methods to Minimize Side Effects

Post-procedure home care determines 30% of the results.

**1. **2. Fluid Intake**: Applying a cold compress for 10 minutes every hour is effective from immediately after the procedure until 24 hours later. Since the effect diminishes rapidly after 24 hours, intensive attention during the initial period is crucial. Maintaining the cold compress pack temperature at 4-8°C is optimal. **2. Fluid Intake**: Consuming 2-2.5 liters of water per day promotes lymphatic circulation and helps drain edema. Caffeinated beverages should be limited as they cause dehydration due to their diuretic effect. **3. Upper Body Restraint Sleep**: Keeping the head 15-20 cm higher than the heart prevents edema from accumulating in the face due to gravity. Sleeping on your stomach or side can cause asymmetrical deformities. Additionally, an anti-inflammatory diet (Omega-3 and turmeric) and the application of Vitamin K cream accelerate bruise recovery. Among products approved by the Ministry of Food and Drug Safety, creams containing arnica extract shorten the duration of bruises by an average of 2 days.

Maximum cold compress effect within 24 hours
Recommended fluid intake: 2-2.5L/day
Upper body elevation: 15-20cm
Arnica cream shortens bruise duration by 2 days

Common misconceptions

Misconception Aqua Peel is safe because it naturally decomposes in the body

Truth The polyacrylamide component of Aqua Peel is not biodegradable. Although some manufacturers promote that the 'hydrogel decomposes into water,' in reality, the polymeric framework remains in the body, and only surrounding water is repeatedly absorbed and expelled. The FDA classifies Aqua Peel as a semi-permanent filler, and surgical excision is required for removal. In Korea, since cases of long-term side effects have been reported since the mid-2010s, the use of products approved by the Ministry of Food and Drug Safety is being emphasized.

Misconception Management ends once the swelling subsides

Truth Even after surface swelling disappears, dermal regeneration continues for 3-4 weeks. If you engage in strenuous activity due to an early return to work, internal tissues may become unevenly positioned, increasing the risk of nodules or asymmetry. In particular, the period up to 2 weeks after injection is when the filler is most likely to shift due to external pressure, as it is not fully fixed to the fascial layer.

Actions strictly prohibited for 2 weeks after the procedure

Exposure to high-temperature environments above 40°C, such as saunas, steam rooms, and hot springs
Alcohol consumption (minimum 72 hours, recommended 1 week)
Vigorous exercise (activities that increase heart rate by more than 30% compared to normal)
Direct pressure, massage, or scrubbing of the injection site
Sleeping on your stomach or leaning to one side
Concurrent treatment with other skin procedures, such as laser or radiofrequency
Taking blood circulation stimulants, such as aspirin or ginkgo leaf extract

Frequently Asked Questions

Can I shower on the day of the procedure?

You may shower with lukewarm water (35-37°C), but you should avoid directing the water stream onto the injection site or scrubbing. When washing your face, lather lightly and rinse, then pat dry with a towel. It is safe to shower with a waterproof bandage on for the first 24 hours.

When can I return to work?

If your workplace involves minimal face-to-face interaction, you can return on days 3 or 4. However, if you have frequent customer interactions or presentations, we recommend returning on days 5 to 7, when swelling has subsided by more than 70%. Bruising can be covered with makeup, but swelling may be noticeable depending on the lighting. I can feel a nodule; will it disappear on its own? Micro nodules smaller than 3mm may be naturally absorbed within 2-4 weeks, but larger ones require confirmation by a specialist. They can be removed via local steroid injection or ultrasound dissolution; however, if left untreated, they may calcify and require surgical excision. Early detection makes treatment much simpler. Is a drink okay? Even a small amount of alcohol (like one can of beer) has a vasodilating effect that worsens swelling. In particular, drinking within 48 hours of the procedure increases the risk of bleeding by more than double. For your safety, please refrain from drinking for at least 72 hours, and preferably for one week. How long do Aqua Peel side effects last? Acute side effects (swelling, bruising, and inflammation) mostly occur within 72 hours. However, delayed side effects such as nodules or migration may appear between 2 weeks and 3 months. Rarely, there have been reported cases of granulomatous reactions occurring after one year, so long-term follow-up is necessary. If you notice any abnormal symptoms, please contact the clinic where the procedure was performed immediately.

How is Aqua Peel removed?

Unlike hyaluronic acid fillers, Aqua Peel lacks degrading enzymes, so it must be removed via surgical excision or suction. Suction removal is possible within the first 3 months due to the high liquid content, but if adhesions to tissue develop over time, an incision may be required. Please make a careful decision considering the difficulty and cost of removal.
