Short answer: this summer's most-searched skincare ingredients clustered around one theme — gentle, ingredient-led care. Familiar soothing and barrier ingredients held strong while a few emerging names surged. Here's a plain-language tour of what actually trended, and what each ingredient does.
As shopping shifted to "show me the ingredient," a handful of ingredients dominated searches through the summer's big sales events. Rather than a shopping list, think of this as a decoder: what each trending ingredient is, and whether the hype matches the mechanism.
The Soothing & Barrier Crowd (Still Winning)
The biggest, steadiest theme was gentle, calming, barrier-supporting ingredients — proof that "soothing is the new anti-aging" is more than a slogan.
- Centella asiatica (cica) — the calming-ingredient poster child, searched constantly. What it does is in centella explained.
- Guaiazulene / azulene — the blue calming ingredient behind a lot of "why is my cream blue" curiosity; more in guaiazulene explained. It's the hero of Klairs' Midnight Blue Calming Cream.
- Vitamin E — a familiar antioxidant that keeps quietly trending; see what vitamin E does, the star of Klairs' Freshly Juiced Vitamin E line.
The Ingredient-Story Stars
A second cluster rode strong ingredient storytelling — molecules with a memorable name and a clear "what it's for."
- PDRN and exosomes — two of the most-viewed ingredient stories of the year, heavy on regenerative-sounding language; we untangle them in cica vs exosome vs PDRN vs guaiazulene.
- EGF — the "growth factor" ingredient people keep asking about; explained in what an EGF serum is.
- Peptides — the gentle "anti-aging without the irritation" favourite; see what peptides do.
The Emerging Names to Understand
Two newer names climbed fast on "non-invasive anti-aging" positioning. They're worth understanding more than rushing to buy: Volufiline, a cosmetic ingredient marketed for a plumper-looking appearance (what Volufiline is), and NAD⁺, a coenzyme appearing in toners and eye creams and closely related to niacinamide (what NAD⁺ is). Both are emerging, gentle-positioned, and still early on evidence — promising to learn about, not miracles to chase.
What the List Really Tells You
Step back and the pattern is clear: people want gentle and they want to understand. The staples that trended are soothing and barrier-friendly; the emerging ones are framed as non-invasive. Chasing every name is a trap — but understanding them, and building on gentle basics with daily SPF, is exactly the literacy that makes ingredient-led shopping work in your favour.
Frequently Asked Questions
What skincare ingredients trended most this summer?
Two clusters dominated: proven soothing and barrier ingredients like centella (cica), guaiazulene/azulene and vitamin E, and strong ingredient stories like PDRN, exosomes, EGF and peptides. A couple of emerging names — Volufiline and NAD⁺ — also surged on non-invasive anti-aging positioning. The common thread was gentle, ingredient-led care.
Why are soothing ingredients like cica and azulene so popular?
They fit the shift toward comfort-first skincare, where "soothing is the new anti-aging." As people moved away from harsh, stripping routines, calming and barrier-supporting ingredients that keep skin comfortable gained lasting appeal. Their steady popularity reflects a preference for gentle care over aggressive quick fixes rather than a passing fad.
Are trending ingredients like PDRN and EGF worth it?
They have strong ingredient stories and genuine interest behind them, but a compelling name isn't proof of a result for your skin. The useful move is understanding what each actually does and whether it suits you, rather than buying on hype. Our individual ingredient explainers cover the mechanisms so you can judge for yourself.
What are Volufiline and NAD⁺, and should I try them?
Volufiline is a cosmetic ingredient marketed for a plumper-looking appearance, and NAD⁺ is a coenzyme appearing in toners and eye creams that's related to niacinamide. Both are emerging, gentle-positioned and still early on evidence, so they're worth understanding rather than rushing to buy. If curious, introduce either slowly and keep expectations modest.
Do I need to buy every trending ingredient?
No. Chasing every trending name tends to overload skin and empty your wallet without matching results. Gentle basics — a suitable cleanser, moisturiser and daily SPF — do more visible work than any single hero ingredient. Understanding the trends helps you choose the few that genuinely suit you rather than collecting all of them.
How do I decide which trending ingredient suits my skin?
Learn what the ingredient actually does and at what kind of use, consider whether it addresses something your skin needs, and introduce it on its own so you can judge it fairly. Favour understanding over novelty, patch test, and remember that a gentle, consistent routine matters more than any single trending addition.
