Recalibrating Skin Back to a Youthful, Acidic pH
Healthy skin is always acidic - this is what keeps it thriving and glowing with radiant vitality.
With the introduction of our new Catalyst Milk Concentrate, RATIONALE’s National Education Manager, Katie Matten, explains the essential role pH plays in maintaining optimal skin health.
THE IMPORTANCE OF AN OPTIMAL PH
pH is a measure of how acidic or alkaline a substance is, with all substances ranging from 0 (very acidic) to 14 (very alkaline) on the pH scale. Healthy skin is reliant on an acidic pH to protect itself from external aggressors such as pathogens, allergens, pollution and environmental stress.
When the outermost layer of the skin - the stratum corneum - is acidic, the skin is able to conserve moisture most efficiently, ensuring a smooth, hydrated, strong barrier. Acidic skin appears clear and luminous. The reverse is the case with alkaline pH - moisture loss is accelerated, enzyme metabolism is compromised and the skin becomes increasingly reactive and sensitive, appearing dry, tired and lacklustre.
While every skin is different, a healthy skin pH should ideally sit between the levels of 4.5 - 5.5. When we’re born, our skin naturally sits within this acidic range - a pH responsible for giving babies their plump, healthy skin. As we age, however, our skin becomes more alkaline. This ageing process can be accelerated by exposure to cosmetic products, where consistent use can unleash a multitude of issues as our skin responds to this assault by constantly trying to rebalance itself - a process that can take up to 72 hours to repair.
THE SOLAR CONSTANT AND SKIN PH
Ongoing exposure to The Solar Constant (comprising Ultraviolet, Visible Light and Infrared Radiation) causes our skin’s pH to become alkaline. Comprehensive environmental skin protection must include Immune Boosters, Antioxidants, and Solar Constant protection, in addition to nightly barrier restoration, pH recalibration and DNA repair. Only this regimen - otherwise known as the RATIONALE Essential Six - can provide all of the necessary protective and repair mechanisms against free radical and immunological DNA damage.
RECALIBRATING SKIN PH
Traditionally, hydroxy acids are deployed to recalibrate skin pH from alkaline to acidic conditions, but in severely sun damaged and sensitized patients, these may not be well tolerated.
For this reason, RATIONALE has pioneered a new paradigm in skin pH optimisation for delicate, reactive skin: Catalyst Milk Concentrate. This precision crafted formulation deploys energising Peptides to gently recalibrate skin pH back to healthy, youthful acidic levels. For sensitive skin, the Catalyst Milk Concentrate forms the all-important Step 5 of the RATIONALE Essential Six ritual.
Skin integrity is reinforced. Balance and calmness are restored.
