Do chemical peels shorten telomeres?

Chemical peels are now a standard practice in many skin care facilities. Glycolic acid, salicylic acid and retinol are commonly used to stimulate cellular turnover. However, if improperly applied, they can initiate premature aging of the skin and, through inflammation, lead to shortening of the telomere.

What causes shortening of telomeres?

Telomere length shortens with age. Rate of telomere shortening may indicate the pace of aging. Lifestyle factors such as smoking, lack of physical activity, obesity, stress, exposure to pollution, etc. can potentially increase the rate of telomere shortening, cancer risk, and pace of aging.

What are telomeres and what happens to cells when they get too short?

When the telomere becomes too short, the chromosome reaches a ‘critical length’ and can no longer be replicated. This ‘critical length’ triggers the cell to die by a process called apoptosis?, also known as programmed cell death.

Does anything counteract telomeres shortening?

Telomerase is a ribonucleoprotein that counteracts telomere shortening and can immortalise human cells.

Do chemical peels cause long term damage?

These problems are more common in people with skin of color and can sometimes be permanent. Infection. A chemical peel can lead to a bacterial, fungal or viral infection, such as a flare-up of the herpes virus — the virus that causes cold sores. Heart, kidney or liver damage.

Does Retinol shorten telomeres?

This is because each time a cell undergoes mitosis, the telomeres on the ends of each chromosome shorten. This is why some experts believe that retinol can actually speed up aging, by shortening the cell renewal cycle.

What causes premature telomere shortening?

Telomeres are short in many patients with inherited or apparently acquired aplastic anemia, and mutations affecting telomerase have been identified in these forms of aplastic anemia; telomerase mutations also have been associated with fibrosis of the lungs and the liver.

What causes telomeres to lengthen?

A small pilot study shows for the first time that changes in diet, exercise, stress management and social support may result in longer telomeres, the parts of chromosomes that affect aging. It is the first controlled trial to show that any intervention might lengthen telomeres over time.

Do skin cells have telomeres?

Telomerase is also active in certain somatic cells such as those in the epidermis but is almost undetectable in the dermis. Telomeres in skin cells may be particularly susceptible to accelerated shortening because of both proliferation and DNA-damaging agents such as reactive oxygen species.

What are two things that happen to telomeres as cells undergo cell divisions?

In addition, with each cell division the non-coding ends of chromosomes (telomeres) get shorter and shorter. Eventually, these telomeres (junk DNA) will get so short that important information will no longer be copied leading to cell death. This, in part, placed a limit on the life of a cell.

Is telomere shortening reversible?

18, 2020 /PRNewswire/ — Tel Aviv University and The Sagol Center for Hyperbaric Medicine and Research at Shamir Medical Center announced today that, for the first time in humans, two key biological hallmarks of aging, telomere length shortening and accumulation of senescent cells, can be reversed, according to a new …
