Post-Procedure Skincare: Ingredient Order Comes First

After a lifting treatment or a skin booster injection, I ask patients to reach first for ingredients that hold water and support the skin barrier, such as hyaluronic acid and panthenol, and to set aside active ingredients like vitamin C and retinol for a few days. The deciding factor is whether injection marks, micro-wounds, or lingering warmth are still present on the skin. When it is safe to restart actives depends on which procedure was done and how recovery is going, so I confirm that timing at a follow-up visit rather than fixing a date in advance.

Hello, I'm Dr. Kim Yeonjin, the director of UH CELL Clinic's Gangnam branch. One of the questions I hear most often as patients are leaving after a procedure is simple: what should I pick up at the pharmacy on the way home? I answer that by talking about ingredients and skin condition first, before I ever mention a product name.

What State Is the Skin Surface In Right Now?

Skin booster injections and microneedling-based treatments such as Potenza leave small, often invisible injection marks and micro-channels behind. Lifting treatments that deliver energy beneath the surface, like Ulthera or Thermage, usually do not break the skin, but they can leave warmth or redness right after the session. I treat both situations the same way: for a short window afterward, I assume the skin is more reactive to irritation than usual, and I guide product choices around that.

Ingredients I Recommend First

• Hyaluronic acid: a basic hydrating ingredient that holds water in the skin and reduces the feeling of dryness.
• Panthenol (dexpanthenol): a 2025 double-blind, randomized study in the Journal of Cosmetic Dermatology divided 60 patients who had undergone non-ablative fractional laser treatment into two groups. The group using a panthenol-containing mask showed significantly lower erythema index scores than the saline-dressing group at day 3, day 7, and day 14.
• A simple, low-fragrance recovery cream or lotion: one familiar moisturizer is easier to monitor for a reaction than several new products layered together.

Gao and colleagues, reporting on that same panthenol study, noted that it was funded by a cosmetics company and looked at only one type of laser. Given that, I present the finding to patients as a reasonable option for supporting barrier recovery rather than as settled proof.

Ingredients to Hold Off On

Vitamin C, retinol (vitamin A), and exfoliating acids are useful in an ordinary skincare routine. On skin with micro-wounds, though, they can increase stinging and redness, so I ask patients to pause them right after a procedure. I do not set one fixed date for restarting these actives for everyone. Once redness and stinging have settled, I decide the restart timing together with the patient at a follow-up visit.

What to Check on the Pharmacy Shelf

South Korea's Ministry of Government Legislation, through its Easy-to-Find Legal Information service, explains that under Article 2 of the Cosmetics Act, a cosmetic is defined as a product with a mild effect on the human body, and that pharmaceuticals under the Pharmaceutical Affairs Act are excluded from that definition. Products intended to treat, manage, or relieve symptoms of a disease are classified as pharmaceuticals instead. Pharmacies stock both categories side by side, so if a package carries a drug label, I recommend checking with a clinician or pharmacist before applying it to a treated area.

I covered the bruising and pain that can follow skin booster injections in a separate article, Rejuran Pain and Bruising: Safer Treatment Starts With Injection Depth.

When to Contact the Clinic

• Redness, warmth, or pain that does not ease after several days, or that keeps getting worse
• Stinging, itching, or a rash after applying a new product
• Any oozing or crusting at the treatment site

If you notice any of these signs, stop using the product and come in for an evaluation.

FAQ

When should I start using sunscreen again?

Sun protection is a basic part of aftercare. In the panthenol study above, participants were also asked to use physical sun protection along with a sunscreen above SPF 30. If a sunscreen stings when you apply it, ask at your consultation which formula would suit your skin better.

I only had a lifting treatment with no injection marks. Do I still need to be careful?

If warmth or redness is still present, I apply the same guidance. Even without visible marks, starting several new active products at once makes it hard to tell which one caused a reaction, so I recommend adding them one at a time.

Can I get aftercare guidance in Japanese or English?

Our Gangnam branch has interpreting staff on site for Japanese, Chinese, and English. If you would like to know which ingredients to use and when to restart them, feel free to ask in whichever language is easiest for you during your consultation.

Individual skin reactions and recovery timelines vary. Please consult a clinician for a diagnosis and treatment plan specific to you.
