TélomèresUn télomère est une région hautement répétitive, donc non codante, d'ADN à l'extrémité d'un chromosome. À chaque fois qu'un chromosome en bâtonnet d'un eucaryote est dupliqué, lors de la réplication, qui précède la mitose (division cellulaire), le complexe enzymatique de l'ADN polymérase s'avère incapable de copier les derniers nucléotides : l'absence de télomère signifierait la perte rapide d'informations génétiques nécessaires au fonctionnement cellulaire.
Les télomères raccourcissent avec l’âge, l’inflammation et le stress. Des études ont montré que des télomères courts sont associés à un risque plus élevé de maladies liées à l’âge.

| Résumé : |
There remain challenges and opportunities to improve the ageing skin as I hope this article has emphasised. I would summarise the achievable goals for non-prescription products as wrinkle reduction, reduction of sebaceous pore diameter, skin smoothing, skin textural improvement of dyspigmentation.
Daily use of effective photoprotective products have been clearly shown to reduce accelerated skin ageing as well as skin cancers and pre-skin cancers.
There are goals that I consider unrealistic and include claims for nonprescription products being able to lift faces, lift and enlarge busts, firm and lift buttocks, cure cellulite, and get rid of enlarged veins and telangiectasia.
At present the technology is not available in my opnion to achieve these goals.
I remain enthusiastic that ongoing collaborative research between dermatologists, dermatologic scientists, skin formulators, cosmetic chemists and marketing specialists will continue to yield benefits for protection, prevention and treatment of ageing skin. |
