Summary
Red LED photobiomodulation effectively reverses skin aging signs, improving skin quality and reducing wrinkles. Results are progressive and last up to a month after treatment cessation, indicating lasting rejuvenation.
Area of Science:
- Dermatology
- Biotechnology
- Aesthetics
Background:
- Photobiomodulation utilizes red light to enhance cellular processes like ATP production and reduce oxidative stress.
- Light Emitting Diode (LED) photobiomodulation is a popular non-invasive therapy for skin aging reversal.
Purpose of the Study:
- To assess the efficacy of red LED photobiomodulation for facial skin rejuvenation over 3 months.
- To evaluate the anti-aging effects of the Skin Light Dior x Lucibel LED mask.
Main Methods:
- A 3-month clinical study on 20 Caucasian women using a red LED mask (630 nm) twice weekly.
- Measurements included wrinkle depth, facial oval relaxation, skin firmness/elasticity, dermal density, roughness, complexion homogeneity, pore size, and sebum regulation.
- Volunteer satisfaction was assessed via self-questionnaire.
Main Results:
- Progressive improvements in skin quality and visible signs of aging were observed over 1, 2, and 3 months.
- All participants reported an overall enhancement in skin quality.
- The treatment demonstrated effectiveness in reducing crow's feet wrinkles and improving skin firmness.
Conclusions:
- Red LED photobiomodulation is effective in reversing visible signs of skin aging.
- The observed rejuvenating effects are lasting, persisting up to one month post-treatment.
- The therapy promotes lasting structural and functional skin rejuvenation.

01:12Renewal of Skin Epidermal Stem Cells
2.5K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:23Tissue Renewal without Stem Cells
1.7K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.

01:14Changes in Skin Color: Clinical Perspectives
2.0K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:15Reticular Dermis
2.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:19Pigmentation
2.5K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
