The beauty aisle is filled with bottles promising to “reverse time.” Serums, creams, and ampoules promise miracles in a drop. However, real skin longevity isn’t bottled. It’s built with decisions we make every single day.

Science (and the mirror) tell us the truth: how you eat, sleep, move, and shield yourself from the environment, matters far more than the most hyped ingredient. The right products help, but they’re the supporting cast, not the whole show.

Our data shows night-time skincare searches are surging, especially for bakuchiol, peptides, and retinol. These actives work while we sleep, tapping into the body’s natural repair cycle. Brands are racing to meet that demand, launching formulas that double down on overnight renewal.

In this guide, we’ll go beyond the bottle – blending science, lifestyle, and prevention – to show you how to keep skin vibrant for the long haul. Spoiler: our pillow, plates, and daily SPF wearing may matter just as much as a standout night cream.

The Science of Skin Aging

Aging isn’t the enemy, but accelerated aging? That’s something we can fight.

Skin changes happen in two ways:

• Intrinsic aging: the slow, inevitable drop in collagen, elasticity, and cell turnover written into your DNA.
• Extrinsic aging: the preventable damage from UV rays, pollution, poor diet, stress, and smoking.

Here’s the good news: research shows up to 80% of visible aging comes from extrinsic factors. Translation? Most of it is in our control.

That’s why powerhouse actives like retinol, bakuchiol, and peptides get so much attention. Retinol – the industry's most loved ingredient – boosts collagen and speeds up cell renewal. Bakuchiol, its plant-based cousin, offers similar benefits with a gentler touch. Peptides act as tiny messengers, telling our skin to repair itself and build more of its structural proteins.

When we combine these ingredients with smart daily habits like healthy eating, sun protection, and restorative sleep we create a one-two punch: prevention and repair. It's no wonder night-time searches for these actives are spiking; brands are responding to consumers waking up to the idea that tomorrow’s glow starts tonight.

Nutrition & Hydration

We can think of our skin as a high-performance engine, given the right fuel it won’t just run, it'll glow. Educating consumers on maximising their skincare routines is key. We need to teach what we can do to maintain our skin as healthy as possible through our food intake.

• Feasting on antioxidants: Think vitamin C (citrus, berries), vitamin E (nuts, seeds), and polyphenols (green tea, colorful fruits). They neutralize free radicals – those invisible skin saboteurs triggered by pollution, stress, and UV exposure –  helping to guard our collagen fortress. For consumers, this translates as having glowing skin, often boosted by using an antioxidant or Vitamin C serum in the morning. By showcasing how your products will support and reduce the effects of hard extrinsic factors, powered by vitamins they recognize, buyers will be more likely to buy them and recommend them. 
• Loading up on healthy fats: Omega-3s from salmon, flaxseed, and walnuts help repair the skin’s moisture barrier, making it more resilient, smooth, and less prone to dehydration. To support these, customers will look directly at products that support their hydration goals. Ingredients such as niacinamide, extremely popular in a lot of serums and creams, are already diffused among consumers, where they immediately recognize it as an important, supportive ingredient for healthy skin. 
• Hydrating inside and out: Water is the base for every skin cell. Pairing it with water-rich foods like cucumber, watermelon, and soups to amplify hydration deep within. More than including hyaluronic acid or other molecules to bring deep skin hydration, educating your consumers on how to potentialize your product is key in maintaining loyalty. For example, if you direct your customers to drink 2L of water in your hydrating serum, and they see healthy, plump skin, they will be more inclined to continue purchasing your products. 
• Cut the sugar crash: Excess sugar doesn’t just spike energy, it triggers “glycation,” where sugar binds to collagen, stiffens it, and speeds up visible aging. Tight, fragile-looking skin? That’s glycation’s handiwork. No serum or cream will be able to cut through accelerated aging if the person wearing it doesn’t stop glycation. By educating consumers to the danger of excess sugar, without bringing a sense of prohibition, the buyer will understand how their habits influence their skincare directly. 

Smart nutrition sets the groundwork for any skincare routine. Combine it with the right skincare actives and we bring nourishment to our skin from the inside out while the products work on the outside. In fact, Hyaluronic Acid, the most common ingredient to bring an hydration boost to the skin, is the 10th most searched ingredient at Covalo. This lets us know that formulators are looking for ingredients that support the skin’s vital functions, such as counter transepidemic water loss over night. 

By having a healthy diet, filled with a variety of foods that support our body’s vital functions, we support the skin’s ability to renew itself and maintain the perfect glow.  

Lifestyle Habits: Sleep, Stress, and Skin Repair

We wear our sleep (or lack thereof) on our face, whether it's shining with vitality or whispering fine lines at sleepy o’clock. Studies show that people getting 7–9 hours of quality sleep have significantly better skin barrier repair, moisture retention, and even faster recovery from sunburn, compared to those sleeping ≤5 hours. Late bedtimes aren’t just about missing our alarm, they’re linked to increased water loss, oil buildup, dullness, and peeling skin. And yet another modern study underlines it: lack of sleep doesn’t just make us tired – it ages the skin, causing dullness, irritation, and rough texture. 

Stress also takes a direct hit at the skin’s health. Chronic stress spikes cortisol, our skin’s worst frenemy. It suppresses repair, ramps up inflammation, and can blow out the delicate balance of the complexion. “As you sleep, your skin’s cells go into overdrive to repair the day’s damage,” says Dr. Ava Shamban, Nicole Kidman’s go-to dermatologist and skincare guru. Her pro tip: Keeping a consistent bedtime routine, simple, and moisture-focused. 

A dermatology approved routine for everyone? Always cleanse, target, then lock in hydration. Let the skin wake up feeling hydrated, not tight. Imagine bringing this directly into your audience by creating a TikTok where you showcase our your products can be used for their night routines. Or making the most of your packaging, and adding a QR for your brands curated nighttime routine. 

So here’s the bottom line: Sleep isn’t just downtime, it’s skin and mind uptime. Even the boldest actives bakuchiol, can’t do their work if your customers are crashing late, stressed, and dehydrated. If you educate your audience to pair these ingredients with stress management and true beauty sleep, you will potentialize your products results and continue building consumers loyalty.  

By creating calming textures, sleeping masks, and soothing oils, brands are supporting consumers on their journey to turn their nighttime routines into a wellness ritual. Through the longevity themes rising up in the beauty industry, actives like exosomes have skyrocketed to be the number 1 most used search term on Covalo. Their technology allows for long-term skin optimization, inflammation modulation, and next-gen cellular regeneration – all key to support the skin’s long term health.

Environmental Protection

Picture this: your customer invests in the best serums money can buy, but daily UV exposure, pollution, and climate stressors continue to accelerate fine lines, pigmentation, and sagging. Here's your opportunity – by designing formulas that go beyond surface-level benefits, you can help them protect, repair, and strengthen skin against these invisible daily aggressors

UV: The #1 Skin Agitator

Up to 90% of visible aging is attributed to UV exposure. Sunscreen isn’t optional; it’s armor. Daily SPF (yes, even indoors with window light) prevents cumulative DNA damage that serums can’t erase. Looking at social media , dermatologists and influencers alike are bringing the importance of SPF on the daily, and how it truly helps the skin aging process slow down. 

Pollution and Free Radicals

City smog and particulate matter act like microscopic shrapnel, triggering oxidative stress that accelerates pigmentation and dullness. Antioxidants (vitamin C, niacinamide, green tea) work like shields, neutralizing the fallout. Targeting your marketing campaign for products including antioxidants towards big city living, will showcase how beneficial your new launch is. 

Climate and Micro-Environments

Air-conditioning dries, humidity clogs, wind strips the barrier. The environment we live in leaves fingerprints on our skin. If you educate your customer on these factors you can help them tailor their care to climate, bringing a personalized approach.

Here’s the clincher: no retinol, peptide, or bakuchiol can fully undo daily environmental assaults. Protection must come first. Prevention is not the boring step, it’s the most powerful longevity tool there is. But ingredients such as CefiraProtect CLR™ by CLR Berlin support the skin's defense against the exposome. By rejuvenating the skin's own antioxidant potential, this ingredient protects the most vital proteins of skin against free radical damage. 

Synergy: Inside Meets Outside

Think of skin like a house. A sturdy foundation (nutrition, sleep, stress management) keeps it upright; a solid roof (SPF, antioxidant defense, preventive care) shields it from storms. Neglect one, and the whole structure falters.

Here’s the magic: inside and outside strategies amplify each other. A diet rich in antioxidants enhances the effectiveness of topical vitamin C. Night creams with peptides or retinol rebuild collagen while your sleep hormones fuel natural repair. And sunscreen locks in the gains by preventing the UV breakdown of all that fresh collagen.

This is why consumers are leaning into complete care systems instead of one-off fixes. And our platform data confirms that brands are answering to this change. The top most searched for ingredients on Covalo reflect how brands are structuring their product development: by leaning into nighttime care and regeneration. When habits and actives work in tandem, the results aren’t just cosmetic. They’re structural, sustainable, and visible for decades.

Much More than Skincare 

Skin longevity isn’t about chasing the next miracle serum. It’s about consistent, compounding choices. A colorful plate, a full night’s sleep, sunscreen every morning, stress kept in check, and actives that repair while you rest.

The rise in night-time searches for bakuchiol, peptides, and retinol shows consumers are already thinking beyond instant results. They want routines that align with biology and lifestyle, a complete inside-out, outside-in strategy.

The takeaway? Start educating your audience now. Create a simple, actionable checklist for their daily routines – protect by day, nourish by night, and let your skin’s natural repair cycle work with you, not against you. By showing how longevity isn’t found in a bottle alone, it’s written in the everyday rituals that shape tomorrow’s skin, you show your clients how your products are not only a one time purchase, but part of a deeper health ritual.
