Helium Ion Microscopy of collagen (Photo credit: ZEISS Microscopy) Skin rejuvenation peptides are cosmetic dermatology’s answer to retinoids. Retinoids stimulate collagen production at the transcriptional level by directly interacting with nuclear receptors. The skin rejuvenation peptides trick the body into synthesizing more collagen. Collagen production and its ultimate destruction by […]

Peptide design for skin rejuvenation

Have you been hurting your patients with lasers, derma rollers or mesotherapy to initiate a wound healing response that promotes collagen synthesis and anti-ageing? I have blogged about a new laser technology from Philips before. But soon you may be able to initiate the same response without causing any injury […]

Hurting the fly

Selective photothermolysis is or rather used to be dogmatic in cutaneous laser systems. Basically laser of a particular wavelength is selectively absorbed by a ‘chromophore‘ that gets heated up. Melanin is the chromophore for hair removal and hemoglobin for blood vessels. What is the chromophore for skin rejuvenation? For non-specific tissue heating […]

Future of Laser Skin Rejuvenation

All cosmetic dermatologists use chemical peels as an anti-ageing service. Chemical peel removes superficial dead cells which will be replaced by younger cells from below. But did you know that the same principle can be applied to internal tissues as well?! Darren J. Baker, PhD, from the Mayo Clinic in […]

Without them, I’m fat and 60.Jack Nicholson A recent study ( ) demonstrated that UVA irradiation of the eyes increased the level of a-MSH and the expression MC1R receptor. Both are involved in pigment regulation and photoageing. The effect was more […]
