MD Prescriptives DNA protection and why this application has an advantage when used under your Sun Protection.


Sun exposure is one of the leading factors contributing to the acceleration of skin ageing. In order to protect and prevent the skin from the damaging UVA/UVB rays one needs to consider the daily application of sun protection in combination with an active formulation preventing and repairing the skin from the inside out. This ensures that the skin DNA is protected and healthy cell longevity is prolonged.


Ageing is categorised according to the following causes;

  • Intrinsic Ageing– this is largely linked to genetics, evidence suggests that the telomeres(protective ends of the DNA Strands) associated with each cell’s DNA will get slightly shorter with each new cell division until they shorten to a critical length leading to cellular senescence, a state of which the cell no longer functions to capacity. We use the term ‘Hay flick limit’ when referring to the number of times a cell is able to successfully divide (40 to 60 times) until cell division stops. Hormones can further impact the way in which we age at a cellular level.
  • Extrinsic Ageing– this is related to environmental and lifestyle factors, the biggest contributor being sun exposure to damaging UVA/UVB rays. Excessive exposure to UV radiation triggers the action of the enzymes Collagenase and Elastase to start actively breaking down Collagen and Elastin. This in turn leads to wrinkle formation and skin sagging. Other contributors can include diet, free radical exposure and smoking.


When choosing a sun protection product you should be sure to select a product that provides UVA and UVB High Protection. The MD Prescriptives SPF50 provides essential protection against UVA/UVB rays and is approved by South African National Standards 1557:2013 as well as ISO 24444, ISO 24443. This sun protection provides water-resistant properties, protecting you for up to 40 minutes in water. Both UVA and UVB rays in excess are detrimental to the skin as it may cause photo-ageing.


Whilst sun protection best protects against extrinsic skin ageing, we need to adapt product protocols to assist with the protection of DNA in the fight against intrinsic ageing. Within the MD Prescriptives Product Range is the MD Prescriptives DNA Protection based on Bio-functional Telomere Science which makes it possible to introduce the enzyme telomerase. MD Prescriptives DNA Protection protects the healthy dermal fibroblasts (the cells that produce collagen and elastin), providing our skin with protection against ageing at a cellular level. Telomerase further prevents the breakdown of the Telomere associated with cellular senescence. By delaying cellular senescence we improve cell longevity and overall skin health.


Using the MD Prescriptives DNA Protection in combination with MD Prescriptives SPF50 ensures that the skin is protected from external factors, in addition the reparation of cellular DNA is maintained and skin ageing is combated. Prevention is always better than cure making these two products in the MD Prescriptives product range the perfect anti-ageing duo.
