Skin Cycling - Embrace the Glow

We are introducing the concept of skin cycling – a skincare regimen designed to give your skin the care it truly deserves. Developed by dermatologist Dr Whitney Bowe, skin cycling is a simple and effective technique that can easily be followed in a four-night cycle.

We’re all guilty of it – using an excessive number of products and potent actives simultaneously. Over-exfoliating and overusing active ingredients can result in more damage than good.

What many people fail to realise is the importance of incorporating rest days into their skincare routines, allowing the skin to repair and recover. Similar to our body needing rest days between exercise, our skin requires periods of downtime to promote skin recovery.

We are happy to introduce RAHN´s concept of skin cycling. Let’s dive into the four nightly steps, packed with suitable ingredients from our ingredients suppliers, that will transform your complexion and leave you glowing.

Night 2: Activate Cell Renewal

Boost your skin’s rejuvenation process for a better skin cell renewal treatment. Apply a serum or cream to target fine lines, wrinkles and uneven texture. Let this powerful ingredient work overnight, stimulating collagen production and restoring your skin’s youthful appearance.

Discover the Secret of Holistic Skin Harmony

The skin cell renewal process is regulated by a programme responsible for activating and deactivating genes. This pro gramme can be negatively influenced by various factors, resulting in the appearance of wrinkles, loss of elasticity and thinning of the skin.

“Young Skin Thanks to Youthful Gene Expression”

LIFTONIN®-QI, a water-based extract of Ganoderma lucidum, has the capability to reset the epigenetic clock to the time of our youth by positively regulating epigenetic processes within the cells.

Nights 3 & 4: Nourish and Restore

During the third and fourth nights, your skin enjoys dedicated recovery time. This is when the skin’s barrier, pH and microbiome are restored, effectively priming your skin for the subsequent reintegration of active ingredients. Hydration is key to healthy, glowing skin.

Discover the Secret of Postbiotic Skin Care

We now know that dry skin can suffer considerably if the skin microbiota is out of balance. It is therefore fundamental to counteract this imbalance, avoiding potential formation of inflamed skin and, in a second stage, atopic dermatitis.

DEFENSIL®-PURE, a postbiotic ingredient obtained from fermenting millet flour with lactobacilli exhibiting prebiotic activities, effectively rehydrates dry skin and enhances the skin’s appearance.

DEFENSIL®-PURE promotes the growth of beneficial bacteria on the skin surface and has the potential to supplant undesirable microorganisms.
