Not just for lobbing in bottles until you've amassed a small fortune (it's true what they say about 'counting the pennies'), copper has long been acclaimed for its healing and health benefits. Chances are your parents wear those jazzy copper bangles (the ones that claim to ease their aching joints) but, though its pain-relieving properties are subject to debate, copper is acquiring a string of skin care accolades - especially in 'peptide' form (don't worry, we'll explain).

A key component of 'healthy' blood (unfortunately, 'healthy' still goes hand-in-hand with 'youth' in medi-speak), GHK-Cu possesses powerful wound-healing properties, as well as having countless skin rejuvenating skillz. A copper tripeptide, the body's levels naturally deplete as we grow older (joy of joys!) and therefore, several skin care brands are harnessing its youth-preserving collagen-, elastin- and overall cell-stimulating brilliance with an entire swathe of blue-hued lotions and potions. 

Copper bonded to a trio of amino acids, GHK-Cu is antioxidant, anti-inflammatory, collagen-boosting, elasticising and brilliant for healing breakouts, fading scars and lessening discolouration caused by spots or sun exposure (phewf!). Predominantly 'anti-ageing', it is also a great way to prolong your skin's general wellbeing - helping to ward against DNA damage that's caused by the everyday onslaught (it shields against toxins, pollutants and stress). 

With consistent use, a 'test group' of women in their 50s found that GHK-Cu improved the thickness, firmness, strength and overall 'resilience' of their complexions, and, there are some biochemists who're certain that copper could soon play an integral role in 'resetting' our genes so our cells behave 'better' for longer. 

So, want a piece of the action? Copper has been creeping into INCI lists for years, but recently it's started making headlines. The Ordinary's new (eagerly-anticipated!) incarnation of bestselling {"Buffet"} comes served with a generous helping of copper peptides to help 'undo' the toll of our stress-addled, urban lifestyles. 

It's also the 'lead story' in Omorovicza's phenomenal {Copper Peel} - a two-phased exfoliant-mask that works wonders in moments; refining uneven skin texture and re-energising your sluggish skin cells while controlling and balancing sebum production to combat congestion and leave your face feeling serene.

Aesop's {Elemental Facial Barrier Cream} is laced with copper PCA to deflect the aggressors and keep any redness at bay while Perricone MD's {Blue Plasma Cleansing Treatment} unites salmon egg enzymes with copper to stimulate healing and keep your complexion 'robust'.

It's also in Alpha-H's brilliant {Vitamin B} serum - a soothing, free radical-fighting elixir that boosts skin's defences and charges cells' batteries so they manufacture the skin-essential 'scaffolding' that maintains 'bounce' and 'stretch'.
