India’s UV Index is rising. Are our sunscreens keeping up?

India is successful the midst of a hotter-than-normal summer, with a heatwave causing temperatures to transcend 40°C to 45°C successful galore regions by April and May. You tin consciousness it connected your skin: fatigue, irritation and unexpected sensitivity.

“I decidedly spot a shift,” says Dr Madhuri Agarwal, laminitis and aesculapian manager of Yavana Aesthetics Clinic, Mumbai. “Sensitive tegument issues and obstruction harm are increasing. Pigmentation that was erstwhile easy treatable is present much persistent, and tanning contempt sunscreen usage is common.” She besides notes an summation successful aboriginal signs of photoaging and sun-induced conditions, specified arsenic polymorphous airy eruption (PMLE), which tin origin a delayed, itchy, oregon burning rash, usually reddish bumps, patches, oregon blisters connected the skin.

Skin nether threat

Beyond the disposable vigor lies ultraviolet radiation, easier to underestimate, but biologically acold much consequential. The UV Index (UVI) measures the strength of ultraviolet radiation reaching the Earth’s surface. At little levels (0–2), vulnerability is minimal. As the scale rises beyond 8, adjacent little unprotected vulnerability tin origin damage. The World Health Organization classifies a UVI of 11 oregon higher arsenic “extreme risk”, wherever tegument harm tin statesman wrong 10–15 minutes. Alarmingly, successful April, Bengaluru recorded an utmost UV scale of 13, according to reports. Chennai and Mumbai routinely recorded UV Index levels of 11–13, according to the The Weather & Radar and The Weather Network pages, real-time UV Index trackers.

“The country’s precocious UV Index is mostly driven by geography, with ozone dynamics, section biology conditions and clime alteration playing supporting roles,” says Anukriti Sharma, biology idiosyncratic and subordinate of the IUCN Commission connected Education and Communication, a planetary web of unpaid experts who usage strategical connection and acquisition to animate enactment for Nature conservation.

Located adjacent to the equator, India experiences aggravated sunlight and agelong summers. “When the prima is precocious successful the sky, ultraviolet radiation travels done a shorter atmospheric path, allowing much of it to scope the surface,” says Anukriti.Interestingly, she notes that successful highly polluted cities, airborne particles tin partially artifact them, acting similar a anemic ‘atmospheric sunscreen.’ 

The UV radiation reaching Earth chiefly consists of UVA and UVB rays (high-energy ultraviolet radiation from the sun). While the ozone furniture blocks astir UVB, astir 95% of UVA penetrates through. UVA besides passes done solid and remains comparatively changeless year-round. UVB causes sunburn, but UVA penetrates deeper, contributing to DNA damage, pigmentation and premature ageing. 

“Melanin [the earthy pigment that gives colour to our skin, hairsbreadth and eyes] offers immoderate earthy protection, but it is not a substitute for sunscreen,” says Mumbai-based cosmetic dermatologist Dr Jaishree Sharad. “People often subordinate prima harm lone with tanning, but melasma, hyperpigmentation, blotchy tegument and premature collagen breakdown are each signs.”

“In India, UVA is the larger concern,” says Dr Agarwal. “We tan easy due to the fact that we person larger melanosomes. Over time, that pigment builds up; this is cumulative UV damage.”

The SPF obsession

SPF has go shorthand for prima protection. It measures defence against UVB rays, and portion higher numbers connection greater protection, the gains plateau beyond a point. SPF 50, for instance, blocks astir 97% of UVB.

“In India, the bigger tegument communicative is UVA. A sunscreen speech that begins and ends with SPF is already outdated,” says Prachi Bhandari, co-founder of Aminu, a skincare marque astatine the cusp of creating multi-functional, innovative formulas for the modern-day Indian consumer. This is wherever the PA++++ standing — developed successful Japan — matters. The much “+” signs, the stronger the UVA protection. 

Dr Sharad points to disposable airy and bluish airy vulnerability from prolonged surface clip arsenic increasing concerns, “Visible daylight itself tin stimulate melanocytes [cells successful the assemblage liable for producing melanin] and trigger excess production,” she says. “Tinted sunscreens containing robust oxides tin connection further extortion against pigmentation triggered by disposable airy exposure.”

Sunscreen whitethorn present beryllium non-negotiable successful skincare, but usage habits stay inconsistent. According to Mintel’s Global New Products Database, sunscreen launches successful India roseate by 235% betwixt 2020 and 2025. Yet Mintel probe from 2024 recovered that lone 14% of Indian adults had utilized sunscreen successful the erstwhile year.

“I don’t blasted the sunscreen itself, but however it’s used,” says Dr Agarwal.

The two-finger regularisation for the look is simply a utile line (plus 1 for the neck), with reapplication particularly important if clip is spent outdoors, sweating oregon spending agelong hours adjacent windows oregon screens. And, staying consistent. “People presume sunscreen is lone indispensable astatine the formation oregon during highest summer,” says Dr Sharad. “But adjacent abbreviated commutes, sitting adjacent ample windows oregon aboriginal greeting walks tin exposure the tegument to important UVA and disposable light.”

Keeping up with UV

The situation isn’t lone behavioural. Experts besides constituent to the deficiency of accordant investigating and benchmarking standards successful India. “If a sunscreen look isn’t stable, you’re fundamentally applying a moisturiser,” says Dr Agarwal. Prachi adds that determination is inactive constricted autarkic photobiological probe connected Indian tegument types to usher formulations.

A increasing consciousness is influencing however sunscreens are being developed. New-generation filters specified arsenic Tinosorb and Mexoryl are designed to connection broader, much unchangeable extortion against UV and disposable airy without degrading arsenic rapidly successful sunlight. Sunscreen preferences are besides shifting towards lighter, much cosmetically elegant formulations that radical are consenting to deterioration consistently successful hot, humid weather. Pharmacy staples specified arsenic UV Doux, Photostable and La Shield stay fashionable for their lightweight gel textures, portion brands similar La Roche-Posay, ISDIN and Eucerin proceed to diagnostic prominently successful dermatologist recommendations for their stronger UVA extortion and invisible finishes that furniture comfortably nether makeup. 

Homegrown brands are besides rethinking texture and wearability — 2 large barriers to sunscreen adoption successful India. Aminu’s Milky Mineral sunscreen focuses connected “environmental defence”, targeting UV exposure, pollution, bluish airy and oxidative accent successful a lightweight look built astir non-nano zinc oxide.

Still, sunscreen unsocial is not enough. Dr Sharad cautions against over-exfoliation and assertive skincare routines, “overusing AHAs oregon BHAs, scrubs and exfoliants tin weaken the tegument obstruction and summation inflammation and hyperpigmentation,” she says, and recommends including antioxidants specified arsenic vitamin C, E and ferulic acerb to support obstruction wellness and trim oxidative stress.

Dr Agarwal suggests dermatologist-guided oral antioxidants to assistance combat escaped extremist damage. “They trim inflammation and dilatory pathways linked to ageing and collagen breakdown,” she says. Treatments person evolved, too. “Earlier, lasers and peels simply cleaned up damage. Now the absorption is regeneration — repairing the tegument barrier, improving insubstantial wellness and adjacent addressing DNA-level damage.”

The aboriginal of prima attraction whitethorn prevarication not successful chasing ever-higher SPF numbers, but successful rethinking however we unrecorded with the prima altogether, and, of course, remembering to reapply.
