Should you ditch retinol and plump for the hot new skin-saver retinal?

Any skincare buff these days knows the secret to youthful skin lies in retinol — a super- effective skin rejuvenator — to speed up new skin cell production and reduce the appearance of wrinkles.

But there’s a new hero product, retinal, and it claims to work 11 times faster.

The ingredients may be only a single letter apart, but there are big differences for your skin. so, should you swap your retinol for its turbo-charged half-sister?

retinal (short for retinaldehyde) is ‘one of the most powerful ingredients in skincare and produces amazing results’, says Daniel isaacs of skincare brand Medik8.

yet there are only a few retinal products so far, because here’s the bad news: it’s expensive and tricky to stabilise for use in cosmetics.

Retinol and retinal speed up the rate at which our skin regenerates and old skin cells shed, which slows as we age. But this super-speedy exfoliation means they can make your skin more sensitive and need to be introduced slowly.

retinoids can tackle a whole host of midlife skin woes, facialist Fiona Brackenbury explains: ‘They help to strengthen the skin barrier, reduce water loss, protect existing collagen fibres and clarify the complexion.’

Where retinal scores over retinol, however, is not just in its warp speed, but in its spot- slaying powers. ‘retinal’s big advantage is its antibacterial properties,’ says Fiona. ‘Less bad bacteria means less chance of breakouts.’

So does the ‘11 times faster’ claim, mean you’ll get the same results from retinal in one month that you’d get from retinol in 11?

in the lab, where this was tested on human skin cells in petri dishes, yes — but in real life, where there are many variables, such as individual skin physiology, not necessarily. so far, there have been no comparisons on real faces.

BOTH retinol and retinal have to be converted into retinoic acid by our skin to be effective

— but retinol takes longer, as it has to go through two conversions, first to retinal, then retinoic acid.

Fiona says: ‘ The health of our skin, our age and our lifestyle, including stresses from pollution and the sun, all influence the skin’s ability to convert the ingredient into a form the skin can use.’

it’s a bit like the couch To 5k running programme, she says, as ‘everyone takes a different amount of time to achieve their goals’.

one advantage of retinal is better results can be had with a lower concentration of the product.

cosmetic chemist Pippa harman, founder of skincare consultation service renude. co, explains: ‘ The strengths needed are typically ten times lower than for retinol,’ she says.

Daniel isaacs recommends 0.03 per cent as a starting point,

compared with about 0.1 per cent for retinol.

What’s more, as retinal is less stable, it has to be ‘encapsulated’, or wrapped in a protective carrier. This means it may not irritate sensitive skin as much as retinol.

‘This brings down the sensitivity potential as it’s released more gradually,’ says Pippa.

as with all retinoids, you should avoid retinal if pregnant, use at night (it can go off during the day) and wear sun cream to protect fresh new skin.

WHAT’S IT LIKE? i’ve used this regularly and it has everything you need for age-proofing skin — and leaves it soft come morning. it’s expensive, but you get a larger tube than the rest.

THE SURPRISINGLY AFFORDABLE ONE

AHC Youth Focus

Pro Retinal 11x Essence 30ml (left), £28.99, superdrug.com WHAT IS IT? ahc is the topselling aesthetic skincare brand in korea, where glowing skin is an obsession. This 0.02 per cent encapsulated retinal serum is a power player in their Pro retinal 11x retinal range.

NO-IRRITATION NIGHT CREAM

STRIVECTIN Advanced Retinol Nightly Renewal Moisturizer, 30ml, £69, feelunique.com

WHAT IS IT? strivectin has worked hard to make this night cream (right) as non-irritating but as potent as possible with a double dose of retinoid (retinal and retinol — both encapsulated, but they don’t say what strength), soothing peptides and a niacinamide- like ingredient, nia 114TM to enhance retinol efficiency and minimise sensitivity. studies have found that it reduced forehead lines and pores after four weeks.

WHAT’S IT LIKE? This is for regular retinol users — but you’ll have to experiment to find your sweet spot. For me, it was once or twice a week to avoid that dry, tight-skin feeling, which can occur because retinoids also reduce oil production.
