research Optothermal response and Tissue Damage analysis during Laser Hair Removal
This study found that laser hair removal is optimal for light to moderate skin tones using 10-15 J/cm² at 755 nm and for dark skin with 4.5-10 J/cm² at 755-1064 nm.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.
research The Effects of Multiple Power Densities of Carbon Dioxide Laser on Photothermal Damage in Rat Skin Tissue
In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.
research Cell and Tissue Damage after Skin Exposure to Ionizing Radiation: Short- and Long-Term Effects after a Single and Fractional Doses
This study found that single high-dose irradiation in mice induced more severe acute skin injury and hair depigmentation, while fractional doses led to longer-term damage in the dermis and subcutis.
research Mdm2-p53 Signaling in Tissue Homeostasis and the DNA Damage Response: A Dissertation
This study found that Mdm2 is critical for limiting p53 activity to maintain normal stem cell function in mouse skin, with impacts on tissue homeostasis and aging.

5 / 761 resultscommunity Could microneedling for the next 5 years cause any permanent damage?
Microneedling for hair loss and its potential long-term effects. Some users believe it can cause fibrosis and scar tissue if done too frequently or deeply, while others claim it has improved their hair loss when done correctly. There is limited scientific research on the topic.
community Injured temple with derma rolling
OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.
community I need some guidance...
A user experienced hair thinning due to traction alopecia from using Murray's Beeswax and is considering treatments like minoxidil and finasteride to reverse the damage. Another user suggests consulting a hair specialist, as the hair may not regrow if scar tissue has formed.
community Does microneedling damage scalp?
Microneedling does not prevent future hair transplants, but some surgeons report the skin becomes "harder" in treated areas. There is no clear evidence to confirm this effect.
community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
