Glutathione Injections: Important Precautions to Know Before Treatment

Glutathione is one of the body's natural antioxidant substances, often used in intravenous or oral form for skin-brightening purposes. However, since it is administered as an injection, skin condition can vary depending on prior consultation and post-treatment care, so it is recommended to carefully review the following information rather than approaching it simply as a trend.

Glutathione Injections: Why Caution Is Needed

Glutathione is a substance naturally produced in the body, but because this treatment involves injecting it directly into a vein at high concentrations, individual reactions may vary depending on one's health condition. In particular, those with allergic tendencies, those taking other medications, or those who are pregnant or breastfeeding should thoroughly consult with a medical professional before the procedure.

In addition, the injection site (such as the arm vein) may temporarily experience tingling, redness, or bruising, and in rare cases, systemic reactions such as hives or dizziness may occur, so it is safer to remain at the clinic for observation immediately after the procedure.

There is a lot of exaggerated information circulating claiming that skin tone becomes 'noticeably brighter in just one session,' but it is important to understand that the degree of perceived effect can vary depending on individual skin type and lifestyle habits.

Post-Treatment Progress — What to Watch for in the Following Days

On the day of the treatment, mild pressure or bruising may occur at the injection site, so it is helpful to avoid excessive use of the arm and to stay well hydrated.

In the 1 to 3 days following the procedure, redness or slight irritation may remain at the injection site. During this time, avoid rubbing or stimulating the area, and since the skin is in a sensitive state, it's best to focus on soothing care with mild formulations.

From day 4 onward, most irritation subsides and the skin begins to stabilize. From this point, it's natural to shift toward moisture-focused care that replenishes deep dryness and improves overall skin condition.

Glutathione injections themselves act internally within the body, but it's not uncommon for people to experience sensitive or dry skin before and after the procedure. During this period, it's best to pause exfoliating treatments or strong acidic products and thoroughly apply sun protection as basic care.

Step-by-Step Home Care — How to Manage Before and After the Procedure

① Before the procedure: Accurately inform your medical staff about any medications you're currently taking, allergy history, and pregnancy status. If you're fasting or not feeling well, it's safer to reschedule.

② Day of the procedure to Day 3: Keep the injection site clean and avoid activities that rapidly increase blood flow, such as intense exercise or saunas. If your skin feels sensitive, it's good to care for it with low-irritation, soothing formulations.

③ From Day 4 onward: Continue applying sunscreen consistently, and if you're hoping for brightening effects, maintaining sufficient hydration to keep the skin in good condition should go hand in hand. If deep dryness is left unaddressed, skin texture can become rough and tone may appear dull.

④ Ongoing care: Since procedures are often repeated at regular intervals, consistently maintaining moisture and barrier care in your everyday home routine between sessions helps sustain overall skin condition.

What Should You Replenish Your Skin With After the Procedure?

Glutathione itself is a treatment aimed at whole-body care, but if your skin feels sensitive or dry during this period, it's a good approach to minimize irritation with soothing care—whether at the injection site or on the face—followed by deep hydration care in stages.

ZXQMAGAZINETERM에이비쥬 Cream is designed as a 2-STEP routine that follows the recovery process after a procedure. In the early stage, when redness or irritation remains, the Ultra Cera-Rich Cream focuses on soothing and barrier care; once irritation subsides and tightness or dryness becomes noticeable, the Hydro Re-Boosting Cream focuses on deep hydration and texture care. This flow can be a helpful reference even when it's not the treated area but the facial skin overall that becomes sensitive.ZXQ

Post-Procedure Recovery Depends on Home Care

Aside from the effects of the procedure itself, it's good to pay attention to your skin during times when your body becomes more sensitive. In the early stage when irritation remains, we recommend the Ultra Cera-Rich Cream to help with soothing and barrier care, and in the later stable stage, the Hydro Re-Boosting Cream to help with deep hydration and texture care, used according to each stage.
