After receiving Rejuran (commonly known as salmon injection), it is perfectly normal to experience small bumps on the face. This occurs because the main component of Rejuran is polynucleotide (PN), which has a high viscosity and is typically injected superficially into the dermis by hand. Skin absorption takes time. In the days following a Rejuran injection, the skin is essentially undergoing a "dermal marathon." Proper management leads to enhanced results, while inadequate care may lead to complications.
Here’s a guide to managing your recovery:
✅ Mental Preparation: Accept the "Imperfections" of the Next Few Days. Your face may appear bumpy immediately after a Rejuran injection. These bumps are a sign of the doctor's precise technique and adequate dosage.
Within 12 Hours: The injection sites are still closing; the skin may appear slightly red and warm.
24-48 Hours: The bumps are most prominent during this period. Do not worry; they are actively dispersing in the dermis.
Days 3-5: The bumps will disappear, and the skin will enter the "drying period," which tests your patience.
✅ Post-treatment 48 Hours: The Essential "Three No's" Principle. These 48 hours are critical for the skin barrier's self-repair; please avoid touching the area.
Do not rub: Even if your face feels bumpy or unusual, do not rub it. This can affect the distribution of the medication and may introduce bacteria into the injection sites.
Do not wash your face too early: Avoid contact with water for 6-8 hours post-procedure. After 24 hours, you may gently wipe your face with saline solution or cooled boiled water, but refrain from using facial cleansers temporarily.
Do not apply makeup: Cosmetics containing powders and pigments can enter the dermis through the unhealed injection sites, potentially causing granulomas or prolonged inflammation.
✅ Post-treatment One Week: Optimal Repair and "Anti-Dryness" Management. During the collagen regeneration process stimulated by Rejuran, a significant amount of skin moisture is consumed, which may lead to a feeling of increased dryness post-treatment. Medical-grade face masks are essential: For the first 3 days after the procedure, apply one medical-grade cooling mask (Class II medical device) morning and evening. Remember to refrigerate them before use; they are highly effective in reducing redness.
Physical sun protection is preferable to chemical: During this period, your skin is highly sensitive,
