1550nm Erbium Laser Treatment Protocol Thiab Cov Lus Qhia Txog Kev Nyab Xeeb
Dec 15, 2025
Cov1550nm Erbium Laser tej tshuabyog ib qho uas tsis yog -ablative fractional laser dav siv nyob rau hauv dermatology thiab aesthetic tshuaj. Kev ua haujlwm kom raug thiab tom qab- kev tswj xyuas kev kho mob yog qhov tseem ceeb los xyuas kom meej qhov ua tau zoo ntawm kev kho mob thaum txo qis qhov tsis zoo. Kab lus no muab cov ntsiab lus dav dav ntawm lubkev kho mob, kev qhia, cov txheej txheem kev khiav hauj lwm, kev xav txog kev nyab xeeb, thiab tom qab- kev kho mob.
1. Txoj Cai Kev Kho Mob thiab Cov Lus Qhia
Cov1550nm Erbium laser txiavyog atsis yog -ablative fractional lasernws lub zog yog selectively absorbed los ntawm dej nyob rau hauv lub dermal txheej. Qhov kev sib cuam tshuam no tsim kev tswj hwmMicrothermal Treatment Zones (MTZs)nrog rau qhov tob tob txog li2 hli.
Cov kev raug mob microthermal no txhawb kev ua kom fibroblast, txhawbHom I thiab Hom III kho collagen, thiab txhim khu elastic fiber regeneration. Los ntawm ib tug naturalraug mob-kho-regeneration voj voog, daim tawv nqaij ua tiav gradual kev txhim kho yam tsis muaj epidermal ablation.
Clinical Indications
- Daim tawv nqaij rejuvenation: enlarged pores, me me daim tawv nqaij laxity, nplua kab
- Pigment-txog tej yam kev mob: melasma, post-inflammatory hyperpigmentation (PIH), pigmented tsaus voj voog
- Stretch marks: cev xeeb tub-txog lossis nthuav dav-txog striae (dawb lossis liab doog-liab)
- Atrophic pob txuv nti: collagen rearrangement nyob rau hauv caws pliav nqaij kom txhim kho kev nyuaj siab nto
2. Tus txheej txheem ua haujlwm
2.1 Pre-Kev Npaj Kho Mob
Kev ntsuas tus neeg mob
- Contraindication tshuaj ntsuam:
- Active herpes kab mob
- Cov kab mob ntawm daim tawv nqaij
- Keloid- tawv nqaij
- Kev xeeb tub
- Keeb kwm ntawm cov tshuaj photosensitizing (piv txwv li, isotretinoin)
- Kev ntsuam xyuas ntawm daim tawv nqaij (Fitzpatrick scale):
- Cov tawv nqaij ntau dua yuav tsum tau txo lub zog kom txo qis tom qab - inflammatory pigmentation.
-
Cov kauj ruam ua ntej
- Ntxuav thaj chaw kho kom zoo.
- Thovcompound lidocaine creamnyob rau hauv occlusion rau30-40 feebkom txo qhov tsis xis nyob.
- Nqa cov duab kho mob raws li tus qauv thiab cim siab - thaj chaw muaj kev pheej hmoo (xws li, zygomatic prominences).
2.2 Hauv -Kev Kho Mob
Ntaus Parameters
- Lub wavelength1550nm (Erbium iav / doped fiber ntau)
- Fractional ceev: 0.7–1.0
- Ntau dua rau cov caws pliav
- Tsawg ntom rau daim tawv nqaij rejuvenation
- Luam theej duab: 2-4 kis rau ib cheeb tsam kho mob
Tsis Muaj Contraindicated Cheeb Tsam
- Upper daim tawv muag mucosa
- Areola
- Qhov chaw mos mucosa
Pom zoo Parameter los ntawm Chaw Kho Mob
| Thaj chaw | Zog | Qhov Loj | Hla | Ntsiab Lus |
|---|---|---|---|---|
| Periorbital | 2–3 W | 10 mm | 2 | Khaws ntau dua lossis sib npaug li 1 mm ntawm daim tawv muag |
| Cheeks (rejuvenation) | 4–7 W | 20 mm | 3 | Txo lub zog los ntawm 20% dhau zygoma |
| Hauv pliaj / Nasolabial folds | 7–10 W | 15 hli | 3 | Scan perpendicular rau wrinkle kev taw qhia |
| Nos | 5–8 W | 10 mm | 3 | Qhov muag tiv thaiv yuav tsum tau |
| caj dab | 3–4 W | 20 mm | 2 | Vertical scanning |
| Pob txuv nti | 9–12 W | 20 mm | 3–4 | Qhov chaw me me + txhawb nqa kev nyuaj siab |
| Stretch marks | 9–12 W | 20 mm | 3 | Luam theej duab raws lub axis ntev, tsis txhob hla |
2.3 Txoj Kev Kho Mob
- Khaws lub tes tshoperpendicular thiab nyob rau hauv tag nrho kev sib cuagnrog daim tawv nqaij.
- Khaws cia10% qhov sib tshooj:
- Tshaj dhau → thermal raug mob
- Kev sib tshooj tsis txaus → tsis kho qhov khoob
- Tsau -cov txheej txheem taw tes lossis zawv zawg yog qhov lees txais.
- Beginners raug qhia kom sivtsau -point mode.
Kev nrawm nrawmNtev: 1-2 cm / s
- qeeb dhau → kub hnyiab
- Ceev heev → tsis txaus
Clinical Endpoints
- Uniform erythema
- Me edema los yog wheal -zoo li o
- Feem ntau daws nyob rau hauv1-3 hnub
Ua kom lub tshuab ua kom txias (cua txias lossis tiv tauj cua txias) ib txhij kom txo cov thermal tsub zuj zuj.
Cov cim ceeb toom (yuav tsum tau kho tam sim)
- Grey-dawb discoloration → epidermal necrosis
- Purpura → vascular raug mob
- Blistering → ntau zog
Kev hloov kho:
- Cov tawv nqaij tawv tawv: txo qis zog thiab txo ib qho dhau
- Cov tawv nqaij rhiab heev / rosacea: lub zog tsawg dua lossis sib npaug ntawm 3 W + kev pab cua txias
2.4 Kev Tswj Tsis Txaus Siab
| Kev Tsis Pom Zoo | Kev tswj hwm |
|---|---|
| Cov pob khaus | Sterile kua + mupirocin + hlawv tshuaj pleev + hydrocolloid hnav khaub ncaws |
| Persisent erythema | 595nm pulsed dye laser + tacrolimus ointment |
| Hyperpigmentation | Hydroquinone + qis-zog loj-spot Q- hloov 1064nm |
3. Tshaj tawm -Kev Kho Mob raws tu qauv
3.1 Kev Kho Mob Tam Sim No (0–24 Teev)
- Txias thiab tiv thaiv - kev kho mob:
Thov cov tub yees kho mob collagen qhov ncauj qhov ntswg rau30 feeb.
- Kev kho qhov barrier:
Siv cov gels uas muajEGFlos yogbFGF ualos txhawb kev tsim kho epithelial.
3.2 Theem Rov Qab (1–7 Hnub)
Kev huv huv
- Ntxuav nrogib txwm saline los yog sterile distilled dej xwb.
- Tsis txhob siv tshuaj ntxuav tes thiab tshuaj pleev ib ce.
Kev Tiv Thaiv Kab Mob thiab Dej
- Cov tshuaj pleev tshuaj tua kab mob feem ntau tsis tsim nyog rau kev kho tsis yog-ablative.
- Yog tias exudation tshwm sim: siv mupirocin thinlyob zaug ib hnub twg.
- Siv kev kho mob- qib moisturizing hnav khaub ncaws (piv txwv li, recombinant collagen) txhua hnub.
Kev Tiv Thaiv Hnub Ci
- Ua ntejtiv thaiv lub hnub lub cev: wide-cov kaus mom brim, UV qhov ncauj qhov ntswg, looj tsom iav dub.
- Sunscreen:SPF 30+ / PA+++ lossis siab dua, rov thov dua txhua 2 teev
Pom zoo npaum li cas: Ntau dua lossis sib npaug li 1 g rau lub ntsej muag puv
3.3 Ntev-Tsev Kho (1–6 Lub Hlis)
- Pibtyrosinase inhibitorstom qab 1 lub hlis:
- 0.3% yog arbutin
- 15% vitamin C derivatives
- Hydroquinone
- Tranexamic acid (tshuaj pleev)
- Tsis txhob siab - qhov chaw sov (saunas, qoj ib ce) tsawg kawg yog 1 lub lis piam.
- Tsis txhob noj cov zaub mov photosensitizing (celery, coriander) thiab tshuaj (tetracyclines).
Cov Tswv Yim Txhim Kho Kev Ua Tau Zoo
- Pob txuv nti1550nm laser + microneedle RF
- Refractory melasma1550nm laser + qhov ncauj tranexamic acid
- Cov koob tshuaj pom zoo: 250 mg, ob zaug ib hnub (hauv kev saib xyuas kev kho mob)
4. Kev pom zoo rau kev kho lub sijhawm
- Yam tsawg kawg ntawm kev sib ntsib:4 lis
- Lub sijhawm pom zoo:txhua 4-6 lub lis piam
- Ib chav kawm puv feem ntau suav nrog2–4 ntu, kho raws li daim tawv nqaij mob thiab kho cov hom phiaj.
Cov ntaub ntawv muab nyob rau hauv tsab xov xwm no yog npaj rau kev tshaj lij hauv kev kho mob zoo nkauj nkaus xwb thiab tsis suav nrog kev kuaj mob lossis cov lus qhia txog kev kho tus kheej. 1550nm Erbium laser kev kho mob yuav tsum tau ua los ntawm cov kws kho mob uas tsim nyog, nrog rau kev kho mob tsis kho raws li tus neeg mob tus mob ntawm daim tawv nqaij, keeb kwm kev kho mob, thiab kev soj ntsuam kev pheej hmoo. Cov txheej txheem kev kho mob tshwj xeeb thiab kev siv tshuaj yuav tsum ua raws li kev txiav txim siab kho mob thiab ua raws li cov cai hauv zos. Cov chaw tsim khoom yuav tsis muaj lub luag haujlwm rau qhov tshwm sim tsis zoo uas tshwm sim los ntawm kev ua haujlwm tsis raug lossis tsis ua raws li cov txheej txheem txheej txheem.
