Many people believe that the modern-day skincare trends are a scam made by the big pharma companies who wish to make more money. This is a recent trend of ‘Anti-Aging’ skincare that keeps yourself on toes for the innate need for women to stay ‘young’ if they wish to be desirable. The beauty industry, in a way, feeds on such societal-made insecurities. But the recent rise in the trend has taken a different turn. While before people did it before to look prettier or fairer, now people are looking at this skincare routine as a way of taking care of themselves rather than doing to match someone else's beauty standards. This is why, this trend has resurfaced in the skin care community. This is the blue light routine.

In today's digital age, where we spend countless hours looking at screens, from phones and tablets to laptops. This constant screen time exposes us to blue light, which research suggests can have negative effects on our skin. It also leads to premature aging and dark spots. The screens also leads to stress, which could further cause harm to skin. While ditching our devices isn't realistic, a growing number of skincare products claim to protect against blue light. But do these products actually work?

What is Blue Light Skincare?

You can find many skincare products that say they protect against blue light, like sprays, creams, gels, and sunscreens. Some promise to undo the damage blue light might cause, while others try to prevent it in the first place. Blue light sunscreens are special because they protect against both the sun's UV rays and blue light. This is what regular sunscreens don't do very well. Regular sunscreens, whether they use chemicals or minerals, don't block blue light as effectively.

However, tinted sunscreens are different. Tinted sunscreens with SPF 30 or higher can protect your skin from blue light, as well as UVA and UVB rays from the sun. This is because of the coloring in the tint. Some newer sunscreens also have special ingredients that help protect against visible light, including blue light. While scientists are still learning about how blue light affects skin, many skin doctors have found it to be helpful for skin.

What is Blue Light and Why Might It Be a Problem?

Blue light comes from screens, TVs, and even the sun. While we used to worry mostly about how it affects our eyes and sleep, now we're learning it might also affect our skin. Some studies show that too much blue light can damage skin cells and speed up aging, leading to wrinkles and uneven skin tone. It can also cause dark spots on the skin. This happens because blue light can cause something called "oxidative stress" in the skin, which is linked to aging. It leads to dead skin cells. Blue light goes deeper into the skin than the sun's UV rays and can make skin cells produce more pigment, causing dark spots. It's important to know that not all blue light is bad. There is a difference between the blue light that comes out of the screens and the blue light that is used from a certain blue light wavelength as a therapy. The latter is used by doctors to treat acne and some skin cancers.

New Oral GLP-1 Pill Delivers Major Weight Loss In Just 36 Weeks

Updated Jun 26, 2026 | 07:00 AM IST

SummaryA new oral GLP-1 drug, aleniglipron, helped participants lose up to 12% of their body weight in 36 weeks. Researchers say the pill could offer a more accessible alternative to injectable weight-loss medications.

A new oral weight-loss drug is showing promising results for people living with obesity or who are overweight. In a phase II clinical trial published in Nature Medicine, participants taking the experimental medication aleniglipron lost up to 12% of their body weight over 36 weeks.

The study included contributions from Robert Kushner, MD, professor emeritus of medicine at Northwestern University and a longtime expert in obesity treatment.

Aleniglipron belongs to the GLP-1 family of drugs, the same class as popular medications such as Ozempic and Wegovy. These treatments help people lose weight by mimicking a natural hormone that reduces appetite, increases feelings of fullness, and helps regulate blood sugar levels.

What makes aleniglipron different is that it comes in pill form. Most currently available GLP-1 medications require injections and often need special storage, which can make them less convenient and more difficult for some patients to access.

Researchers believe an oral option could make treatment easier for many people. Because aleniglipron is a small-molecule drug—meaning it is chemically manufactured rather than peptide-based—it can be produced more efficiently and potentially at a lower cost.

“Aleniglipron is different because it’s a small molecule that can be taken with or without food,” Kushner said. “Most medicines people take every day, from aspirin to blood pressure drugs, are small molecules. That also creates opportunities to combine it with other treatments in the future.”

If further studies confirm its safety and effectiveness, aleniglipron could offer a more convenient alternative to injectable GLP-1 medications and help expand access to obesity treatment.

Why Is GLP-1 Drug A Medical Breakthrough?

Dr Shubham Vatsya explains that it took 20 years of research for scientists to come up with these medicines. This drug underwent proper lengthy trials, and have been approved by the US Food and Drug Administration (FDA), "which is not obtained by giving any bribe".

He also noted that when a person is not able to lose weight, Ozempic and drugs alike give a "head start" to them, along with a hope.

Talking about side effects, he says that every drug has its side effects, this is where a doctor's role comes in.

"Now, the person who is not able to lose weight, if you tell him 'you hit 100 kg bench press', he will break his shoulder. He needs a kickstart somewhere. This is what weight loss drugs allow," he says.

He also points out that the scientists who made GLP-1 agonists got a Nobel Prize, which "cannot be a scam". This is what makes weight loss drugs truly different.

What Are GLP-1 Drugs?

GLP-1 Drugs stand for Glucagon-like peptide 1, a naturally occurring hormones that helps regulate blood sugar and appetite after eating. It was first identified almost 50 years ago and scientists have since uncovered its role in type 2 diabetes.

How AC Exposure Causes Neck And Back Stiffness

Updated Jun 25, 2026 | 01:00 PM IST

SummaryCold air rarely works alone. Bad posture, sitting too long, skipping exercise, and not stretching enough all add to the problem.

Air conditioners feel great when the weather turns hot and sticky. Most of us spend hours under one, at home, at work, or even on long drives, and it barely crosses our minds. But sitting in cold air for too long can quietly leave your neck and back feeling tight and sore. AC isn't going to cause a serious spine problem on its own, but it can tighten up your muscles and make existing pain worse.

Why Does This Happen?

Muscles function optimally when they are relaxed and warm. As soon as the cold air comes into contact with them, the body automatically starts tightening them as it seeks to retain its warmth. When this occurs in places such as the neck, shoulders, and lower back regions, there is a chance that these muscles will get sore and stiff. This condition worsens even more if the cold air continues to blow in the same spot for hours, especially while sleeping or sitting at a workstation.

What It Does To Your Neck And Back

Your neck and back rely on several muscles to keep you upright and moving properly all day. Cold air can slow blood flow to these muscles, which makes them tense up more easily. That's why people often wake up with a stiff neck after sleeping under an AC vent or feel upper back pain after a day in a freezing office. If you already deal with something like cervical spondylitis or chronic back pain, cold air can make those symptoms flare up even more.

It's Not Just The AC

Cold air rarely works alone. Bad posture, sitting too long, skipping exercise, and not stretching enough all add to the problem. Picture sitting at a computer for hours in a chilly office: that's tense muscles and poor posture combining at the same time, which makes stiffness and pain even more likely.

Simple Ways To Avoid It

A few small changes can make a real difference: keep the airflow away from your neck and back, set the temperature to something comfortable rather than freezing, get up and stretch every so often, drink enough water, and keep a light sweater or shawl nearby if it gets too cold.

AC keeps us comfortable when it's hot outside, but too much cold air for too long can leave your neck and back stiff and achy. A little attention to airflow, posture, and movement throughout the day can help you stay comfortable without paying for it later.

Vitiligo is an autoimmune condition that causes pigment loss in patches of skin. It is highly treatable and does not spread from person to person. However, stress, poor sleep, diet, and overall immune health may influence how active the condition becomes, experts said today on World Vitiligo Day.

Awareness around vitiligo remains low and is often clouded by misconceptions. Observed annually on June 25, World Vitiligo Day aims to raise awareness and challenge the stigma associated with the condition.

HealthandMe spoke to experts to understand the disease and the factors that may affect it.

Dr. Rashmi Ranjan, Consultant – Dermatology, Yatharth Super Speciality Hospital, Noida, said the biggest misconception is that vitiligo is contagious.

"It cannot spread from one person to another through touch, sharing food, or close contact."

Dr. Rashmi told HealthandMe that many people also incorrectly believe vitiligo is caused by poor hygiene or specific foods, claims that are not supported by scientific evidence.

What Is Vitiligo?

Vitiligo occurs when the body's immune system attacks melanocytes, the cells responsible for producing skin pigment. While the condition is not life-threatening, it can have a significant emotional and psychological impact.

“As a chronic autoimmune disorder, vitiligo develops when the body's immune system mistakenly attacks melanocytes—the cells responsible for producing skin pigment. The result is the appearance of white patches that can develop anywhere on the body and may gradually increase in size or number over time,” Dr Hetanshu Parekh, Consultant Plastic Reconstructive & Cosmetic Surgeon, Bhailal Amin General Hospital, told HealthandMe.

The Emotional Impact of Vitiligo

The theme of World Vitiligo Day 2026 is "From Stigma to Strength".

According to Dr. Rashmi, visible skin changes often attract unwanted attention, questions and social judgment. Some people may avoid social gatherings or experience challenges in relationships and employment because of persistent misconceptions.

Children may face bullying, while adults can struggle with anxiety and low self-esteem. Emotional support from family, friends and healthcare professionals is therefore crucial.

A recent study also highlighted a strong link between vitiligo and mental health in India. Nearly 89% of patients reported moderate to severe depression, while close to 60% said they covered their patches, underscoring the continuing impact of stigma.

Vitiligo and the Role of Lifestyle Factors

Dr Hetanshu said vitiligo is often viewed as a skin condition alone, but the disease is far more complex. He explained that

Stress

  • Stress can disrupt immune balance and increase inflammation, potentially worsening vitiligo.
  • New or expanding patches are often observed after major life events such as exams, work pressure, illness, financial difficulties or bereavement.

Sleep

  • Quality sleep is essential for immune regulation and overall health.
  • Chronic sleep deprivation, irregular sleep schedules or less than six hours of sleep may worsen autoimmune conditions, including vitiligo.

Diet

  • There is no specific "vitiligo diet" and no food can cure the condition.
  • Deficiencies in Vitamin B12, Vitamin D, folate and copper may affect immune and skin health.
  • Experts recommend an anti-inflammatory diet rich in fruits, vegetables, whole grains, nuts, seeds and omega-3 fatty acids.
  • Smoking and excessive alcohol consumption should be avoided.

Skin Protection

  • Repeated friction, cuts, burns and excessive sun exposure may trigger vitiligo patches (Koebner phenomenon).
  • Use sunscreen regularly, wear protective clothing and avoid unnecessary skin trauma from tight straps, jewellery or repetitive rubbing.

Is Vitiligo Treatable?

Advances in targeted topical medications, phototherapy and immune-modulating therapies have expanded treatment options and enabled more personalized care, said Dr. Rashmi told HealthandMe.

Dr Hetanshu stressed that lifestyle measures should complement, not replace, medical treatment. Treatment measures include:

  • For small, stable patches, doctors commonly prescribe corticosteroid creams and tacrolimus ointment.
  • More extensive or rapidly spreading vitiligo may require narrowband UVB phototherapy, excimer laser therapy, oral corticosteroids or newer JAK inhibitors such as tofacitinib and ritlecitinib.
  • Patients with stable disease for six to twelve months may be candidates for surgical procedures such as skin grafting and melanocyte transplantation.
  • Medical tattooing and camouflage techniques can help in difficult-to-treat areas.
