Dr. David Kim’s Hand Skincare Routine Highlights an Overlooked Area of Skin Ageing

In dermatological circles, the face often receives the lion's share of attention, yet board-certified dermatologist Dr. David Kim highlights that the hands are frequently the first place to show significant signs of ageing and environmental damage. Because the skin on the hands has fewer oil glands and is constantly exposed to irritants, it requires a high-intervention approach to maintain its integrity. Dr. Kim’s specialised routine is designed to move beyond simple "hand cream" and into a structured medical-grade regimen that restores the skin barrier and regenerates tissue overnight.

Identifying the Vulnerability of Hand Skin

The first step in Dr. Kim’s approach is acknowledging that the hands are uniquely susceptible to barrier damage. Unlike the face, hands are subjected to repeated washing, harsh sanitisers, and mechanical friction, which strip away the natural lipids that keep skin supple. Dermatological research indicates that because the hands have fewer sebaceous (oil) glands, they lack the "built-in" moisture reservoir found on the face, leading to faster water loss. This chronic depletion causes the skin to become thin, brittle, and prone to micro-cracks. By identifying the hands as a high-risk area for premature ageing, this routine shifts the focus from occasional cosmetic use to a daily necessity for skin health.

Ceramide-Based Restoration

Dr. Kim places Ceramide-based moisturisers at the core of his routine to directly address the structural needs of the stratum corneum. Ceramides are essential lipid molecules that act as the "mortar" between skin cells, forming a waterproof seal that prevents transepidermal water loss. Clinical evidence shows that applying ceramide-rich formulas helps repair a compromised barrier much more effectively than standard lotions. For the hands, this replenishment is crucial for reducing the scaling and irritation caused by daily environmental stressors. By focusing on barrier repair first, the routine creates a stable foundation, allowing the skin to actually retain the benefits of any subsequent anti-ageing treatments.

Regenerative Support with PDRN

To address the thinning and loss of elasticity that characterise ageing hands, Dr. Kim incorporates PDRN (Polydeoxyribonucleotide) ampoules. PDRN consists of DNA fragments, often derived from salmon, that act as a bio-stimulant for tissue repair. In the skin, PDRN activates adenosine A2A receptors, triggering a "wound healing" cascade even in the absence of an actual injury. This process stimulates fibroblasts to produce new collagen and elastin, thereby thickening the skin and improving overall texture. While PDRN is a mainstay in advanced facial rejuvenation, its application on the hands marks a shift toward treating this area with the same biological sophistication once reserved for the face.

Occlusion with Petrolatum

To ensure that these active ingredients aren't lost to the environment, Dr. Kim recommends sealing the routine with a heavy Occlusive, such as petrolatum. Occlusives work by forming a physical, hydrophobic barrier on the skin's surface, reducing water loss by up to 98%. In a hand-care context, this step is non-negotiable because the hands are constantly exposed to dry air and water. Petrolatum acts as a "second skin," trapping the ceramides and PDRN ampoule beneath it to maximise their penetration. This "soak and smear" philosophy ensures that the moisture level in the stratum corneum remains high enough for cellular repair processes to occur efficiently.

Overnight Cotton Glove Occlusion

The final, transformative step of Dr. Kim’s routine is the use of Overnight Cotton Gloves. This method, known as "wet wrap therapy" or extreme occlusion, maintains a stable healing environment for several hours while you sleep. During the night, the body’s repair mechanisms are most active, and the cotton gloves serve two primary purposes: they prevent the products from rubbing off onto bedding, and they create a sealed "mini-spa" environment that forces hydration deeper into the tissue. Because cotton is breathable, it allows for this intensive occlusion without causing the overheating or irritation associated with synthetic materials. Waking up after a full night of glove-protected repair often results in a visible improvement in skin softness and barrier resilience that cannot be achieved with daytime application alone.
