Sun Care Science From Hada Labo Tokyo

Friday 22nd Jul 2022 |

A reckless approach to sun care is putting huge numbers of Brits at risk of skin damage, premature ageing and melanoma, new research reveals.

Nine out of ten women admit they have under-estimated the strength of UK sunshine. Four out of five have suffered a bout of sunburn as a result and more than a third (38%) have sustained multiple episodes of sunburn — which dramatically increases the risk of skin cancer.

However, what really alarms experts is that the new research — conducted for the Japanese skincare specialists and the brains behind the next generation new sun-care innovation – Hada Labo Tokyo[1] — shows that two-thirds (65%) suffered sunburn despite having applied a sunscreen.

GP and TV medic, Dr Hilary Jones notes: “This is a very important take-home message, we not only underestimate the power of the sun when we’re at home, we also underestimate what is needed to protect against sunburn.

“Everyone knows the risks of sun damage. There are almost 17,000 new cases of melanoma skin cancer and around 2,300 preventable deaths every year,[2] and those numbers are rising steadily.[3]

Millions of pounds are spent on awareness campaigns, yet there continues to be a potentially lethal gap between awareness and actions.”

High-risk habits

The new Hada Labo Tokyo real-world research highlights the dangerous extent of women’s high-risk habits:

  • Only a third (34%) of those surveyed use a sunscreen every day.
  • Almost half (47%) took fewer precautions against sunburn at home than when they’re away.
  • On high-risk sunny days, 47% use only one application of sunscreen.
  • 36% only use sunscreen when it’s hot
  • 10% of women never use a sunscreen in the UK

A number of factors are driving this:

  • On average, we miss 10% of our face when applying sunscreen.[4]
  • Sunscreens should be applied 30 minutes before sun exposure.[5]
  • Protection should be reapplied every 2 hours.[6]

Experts believe another hugely important factor is how pleasant a product is to use.[7] Skin expert and make-up artist from Hada Labo Tokyo, Gina Akers explains: “Gloopy textures, chemical smells, ingredients which irritate sensitive skins and products that leave the skin feeling greasy can all factor into our reluctance to use sunscreens effectively.”

Science of sun care

Now Hada Labo Tokyo, the cult beauty brand from Japan, has addressed these challenges with two new sun care products which combine the very latest skin science and innovations from the East with strength European sunscreen standards and regulation.

Hada Labo Tokyo’s water-resistant moisturising sunscreens — in  50SPF face cream and sun lotion formats — protect against sunburn and the signs of ageing on multiple fronts:

Three different UV filters provide proven protection against both UVA and UVB via physical and chemical modes of action.

Anti-ageing ingredients include three forms of hyaluronic acid:

  • Sodium Hyaluronate — a water-binding hydration hero which helps replenish moisture lost from the outer-most layer of skin. Each molecule can hold up to 1000 times its weight in water.
  • Super Hyaluronic Acid — also known as sodium acetylated hyaluronate, which was developed to increase affinity with the skin and lock in moisture to provide prolonged hydration.
  • Nano Hyaluronic Acid — also known as hydrolysed hyaluronic acid, is made up of even smaller molecules, to maximise moisture retention deep with the epidermis and help combat wrinkles and other signs of ageing.
  • Squalane — a moisturising lipid, which is found in human sebum, helps to repair the skin barrier, boosts collagen and counteracts wrinkles.
  • Panthenol — an antioxidant and lubricant derived from vitamin B5 which enhances the appearance and feel of the skin.

Clinical trial data

A dermatologist-controlled clinical trial recruited  women and men aged from 23 to 68 was put into place to test the Hada Labo Tokyo Water-Resistant Moisturising Sunscreen: Sun Lotion SPF 50 to use the product in range of real-world settings, including sun-bathing, for 28 days. Participant scores on usability were combined with laboratory tests to monitor skin changes.[8]

Key findings include:

100% of trial participants agreed the sunscreen:

  • Provides a long-lasting and strong moisturising effect
  • Is easy and pleasant to apply
  • Can be worn under make-up (100% of women)
  • Doesn’t leave white streaks
  • Sand does not stick to the cream on application
  • 96% said it was quickly and completely absorbed
  • 92% reported it regenerates skin and had a light, non-greasy formula
  • 88% said it left skin dry to the touch and looking matt
  • 84% confirmed it had firmed their skin
  • 64% said small wrinkles were less visible.

Before and after assessments of skin hydration via a Corneometer — a clinically recognised  precision tool used to measure moisture in the epidermis — showed:

  • An average 14% increase in skin hydration in 28 days[9]
  • A 23% increase in skin moisture in one super-responder participant[10]

Analysis of wrinkles using a Primos 3D Lite showed:

  • 100% of participants had fewer wrinkles overall
  • Average reduction in wrinkle count was 14%
  • Length of wrinkles was reduced in 90% of participants
  • Average reduction in wrinkle length of 4%
  • Depth of wrinkles reduced in 70% of participants
  • Average reduction in wrinkle depth: 3%
  • Wrinkle area reduction in 100% of participants, with average of 5% less

Radiation hazards

UVA rays have a longer wavelength and are primarily associated with skin ageing UVB has a shorter wavelength and commonly cause burning.

Pigmentation disorders are strongly linked to UV exposure. One research team concluded that environmental factors — especially sun exposure — influence clinical signs of ageing, and UV exposure may be the cause of 80% of visible signs of facial ageing.[11]

Dr Hilary Jones warns: If you get sunburnt once every two years, or 10 times in a decade, your risk of developing melanoma skin cancer roughly trebles compared to people who’ve never had sunburn.

“Another study showed that combined analysis in the International Journal of Cancer found that women who’ve had ‘painful’ or ‘severe’ sunburn at least 26 times in their life have a two to three times higher risk of developing melanoma skin cancer.”[12]

Hydration hero

Hyaluronic acid has a phenomenal capacity to lock water in and keep connective tissues hydrated. On average, and adult has around 15g of HA, with a third of this found in the skin — but our levels begin to fall in our twenties and have halved by the time we are 50.[13],[14]

Japan — the home of Hada Labo Tokyo — leads the way in the science of HAs. Japanese scientists pioneered the techniques used to create nano-size particles of HA which can penetrate deep into the dermal level of the skin.

These water-resistant moisturising sunscreens not only provide excellent UVA and UVB protection, but they also deliver sustained skin hydration and effective anti-ageing ingredients with the luxury of a premium beauty brand.

Gina Akers adds: “As anyone who has already tried a product, or more, in the Hada Labo skin-care range, once you’ve experienced the power of these ultra-light formulations there’s no going back to the brands you’ve used in the past.”
