Crepey skin on the arms and body is primarily caused by the degradation of collagen and elastin fibres within the dermal layer, leading to skin that appears thin, wrinkled, and reminiscent of crinkled tissue paper. Unlike typical expression lines, crepiness is driven by a combination of intrinsic chronological ageing and extrinsic environmental factors, most notably cumulative ultraviolet (UV) radiation exposure which accelerates the breakdown of the extracellular matrix [1]. In Australia’s high-UV environment, photoageing significantly thins the epidermis and reduces the skin’s ability to retain moisture, making the structural fragility more apparent [2].
To effectively 'fix' or improve the appearance of crepey skin, a multi-modal approach is required. Topical retinoids (Vitamin A derivatives) are the gold standard for stimulating collagen production and increasing epidermal thickness [3]. Additionally, incorporating high-performance moisturisers containing humectants like hyaluronic acid and occlusives like ceramides can temporarily plump the skin and restore the lipid barrier. For long-term structural improvement, consistent broad-spectrum sun protection is essential to prevent further elastosis and dermal thinning [4].
At a cellular level, crepey skin is characterised by a significant reduction in Type I and Type III collagen, alongside the disorganisation of elastic fibres, a process known as solar elastosis. The fibroblasts, which are the cells responsible for synthesising these structural proteins, become less active as we age, leading to a net loss of dermal density. Furthermore, a decrease in glycosaminoglycans (GAGs) reduces the skin's natural turgor and hydration levels [1], [5].
In the Australian climate, the skin's 'barrier function' is often compromised by chronic dehydration. When the stratum corneum lacks sufficient lipids and moisture, the underlying structural deficiencies become visually exaggerated. Scientific intervention focuses on both 'resurfacing' the top layer to improve texture and 'remodelling' the deeper layers to restore elasticity through active signalling molecules like peptides and retinoids [2], [6].
For those looking to address the loss of structural integrity in the skin, AUREME formulated the Cellular Thread peptide treatment serum with a specialised Cellular Peptide Complex and Kakadu Plum to support firmness and skin longevity. Complementing this with a rich barrier-sealing moisturiser like Cellular Crème, which includes Sodium Hyaluronate and Shea Butter, can help maintain essential suppleness and minimise the visible thinness associated with a compromised dermal matrix.
FAQ
Can topical creams really reverse the appearance of crepey skin?
While topical creams cannot fully reverse structural damage, formulations containing prescription-strength retinoids or high-concentration retinol have been clinically shown to increase dermal procollagen and improve skin texture over 6–12 months [3]. Moisturisers containing alpha-hydroxy acids (AHAs), such as lactic acid, also help by exfoliating dull surface cells and stimulating cellular turnover, which thickens the viable epidermis and smooths the surface [6].
How does sun exposure specifically contribute to crepiness in Australia?
Australia experiences some of the highest levels of UV radiation globally, which triggers the production of matrix metalloproteinases (MMPs). These enzymes actively break down collagen and elastin fibres in a process called photoageing [4]. This structural collapse happens much faster than natural chronological ageing, leading to the premature 'crinkling' effect seen on sun-exposed areas like the forearms and decolletage [2].
Does hydration and diet play a role in fixing crepey skin?
Systemic hydration is important for general skin health, but topical hydration is more effective for immediate plumping of crepey areas. Research suggests that diets high in antioxidants and omega-3 fatty acids may support the skin's defence against oxidative stress, though they cannot replace the efficacy of direct topical treatments like sunscreens and retinoids [5], [7].
