NAD+ Drips and Peptides: Could Biohacking Change Anti-Ageing?
Anti-ageing has traditionally focused on the skin, with sunscreen, retinoids, injectables, lasers and other cosmetic treatments used to address visible signs of ageing. Now, the conversation is moving towards treatments that claim to influence ageing from inside the body.
NAD+ drips and peptide therapies have become part of the growing longevity and biohacking market, with clinics promoting them for energy, recovery, metabolism and healthy ageing. Celebrity and influencer interest has also brought these treatments to a wider audience.
The science, however, is more complicated than the marketing.
Why NAD+ Is Getting Attention

Nicotinamide adenine dinucleotide, or NAD+, is a coenzyme found throughout the body. It plays a role in energy production, cellular signalling and DNA repair. NAD+ availability appears to change with age, prompting researchers to investigate whether increasing it could influence some processes associated with ageing.
One of the more visible treatments is intravenous NAD+, delivered through a drip. Wellness clinics promote NAD+ infusions for concerns including fatigue, recovery, cognitive function and longevity.
But understanding what NAD+ does biologically is different from proving that an infusion slows ageing.
A 2026 systematic review in Ageing Research Reviews found evidence that oral NAD+ precursors, including nicotinamide riboside and nicotinamide mononucleotide, can increase NAD-related biomarkers. However, evidence that these changes consistently translate into meaningful improvements in health remains limited.
The distinction is important because changing a biological marker does not automatically mean fewer wrinkles, better memory, improved physical performance or a longer lifespan.
There is also a difference between oral NAD+ precursors and intravenous NAD+. A 2026 study of commercially administered IV NAD+ reported short-term findings, including tolerability and exploratory metabolic outcomes, but this does not establish that NAD+ infusions slow human ageing.
Where Peptides Fit In

Peptides are short chains of amino acids that perform different functions in the body. Some peptide-based medicines have established medical uses, while others are still being investigated.
At the same time, peptides are increasingly marketed through longevity clinics and online communities for claims involving muscle recovery, fat loss, sleep, skin health and other aspects of ageing.
This makes the word “peptide” particularly easy to misunderstand. An approved peptide medicine and an experimental compound marketed online for longevity do not have the same evidence, regulation or safety profile.
Peptides are also common in topical skincare, where certain formulations are marketed to improve the appearance of firmness and fine lines. Applying a peptide serum to the skin, however, is very different from injecting a peptide into the body. The route of administration affects the dose, potential risks and biological effects.
What Does Biohacking Really Offer?

Longevity research is investigating processes including cellular energy production, DNA repair, inflammation, mitochondrial function and metabolic health. NAD+ is part of this research because of its role in several cellular processes.
But promising biological research does not automatically produce a proven treatment.
For consumers considering a longevity therapy, the important questions are what has actually been tested, in whom, at what dose, by which route and for what outcome.
Cost is another consideration. Repeated infusions or injectable treatments can become expensive, particularly when they are offered as ongoing wellness programmes.
There are also safety questions. IV treatment is an invasive procedure, while injectable peptides may carry risks related to the compound, dosing, contamination or product quality. These concerns are particularly relevant when substances are obtained through poorly regulated online sources.
Conclusion

Some of the best-supported approaches to healthy ageing remain conventional: regular exercise, adequate sleep, a balanced diet, avoiding smoking and managing cardiovascular risk.
That does not mean NAD+ or peptide research should be dismissed. Some treatments may eventually prove useful for specific aspects of ageing or age-related disease.
For now, though, the evidence does not support treating NAD+ drips or experimental peptide injections as established anti-ageing therapies.
The next step is better human research showing whether changing these biological pathways produces meaningful improvements in health and function over time. Until then, biohacking remains an emerging area of longevity research, not a proven shortcut to slowing ageing.

4 Steps to Glowing Skin, According to Experts
Healthy-looking skin does not require a bathroom shelf full of products. A consistent routine that cleanses, moisturises, addresses specific concerns and protects against the sun can provide a stronger foundation for the complexion. The key is choosing products that suit your skin and using them consistently.
Cleanse without overdoing it

Cleansing removes sweat, excess oil, sunscreen and makeup from the skin. A suitable cleanser should do this without leaving the face feeling tight or uncomfortable.
A simple routine is often easier to maintain than one built around multiple products. Start with a cleanser suited to your skin type, particularly if your skin is sensitive or prone to dryness.
At night, cleanse your skin thoroughly if you have worn makeup or sunscreen. In the morning, your routine can depend on how your skin feels. If it is dry or sensitive, a gentle cleanser may be preferable to a stronger formula.
Keep your skin moisturised

Hydration is important for all skin types, including oily skin. When the skin barrier is disrupted, it can become dry, flaky, tight or more sensitive.
Moisturisers containing ingredients such as glycerin, ceramides, hyaluronic acid or squalane can help support the skin’s moisture levels. The right texture also matters. Oily or acne-prone skin may be more comfortable with a lightweight lotion or gel, while dry skin may benefit from a richer cream.
Moisturising is particularly important when using active ingredients that can cause dryness or irritation. Supporting the skin barrier can make a treatment routine easier to tolerate.
Choose a treatment for your main concern

This is where your routine should reflect what you want to improve.
For uneven pigmentation, ingredients such as vitamin C can be considered. Salicylic acid is commonly used for acne and clogged pores, while retinoids can help with acne, uneven texture and signs of skin ageing.
Avoid introducing several strong active ingredients at the same time. Doing so can increase the risk of irritation and make it difficult to identify which product is causing a reaction. Introduce treatments gradually and give your skin time to adjust.
Most importantly, choose a treatment based on your skin concern instead of adding products simply because they are popular.
Wear sunscreen every morning

Sun protection should be part of your morning routine, even when the weather is overcast. UV exposure contributes to premature skin ageing, pigmentation and other forms of skin damage.
Choose a broad-spectrum sunscreen with at least SPF 30 and apply it generously to exposed skin. If you are spending extended periods outdoors, reapply as directed, particularly after sweating or swimming.
For people dealing with pigmentation, a tinted sunscreen may also be worth considering. Some tinted formulas contain iron oxides, which can provide additional protection against visible light that may worsen hyperpigmentation.
Glowing skin is not about making the face look shiny. It is more useful to think about maintaining skin that is hydrated, protected and comfortable while addressing specific concerns with appropriate products.
A routine does not have to contain numerous steps to be effective. Start with the basics, introduce treatments according to your needs and give the routine enough time to work before deciding that you need something else.

Why Dry Brushing Is Finding a Place in Everyday Body Care
Dry brushing is a simple body-care technique that involves moving a firm-bristled brush over dry skin, usually before a shower. It has become popular among people looking for ways to smooth rough skin without adding another product to their routine.
Its clearest cosmetic benefit is exfoliation. The bristles help loosen dead skin cells from the surface, which can leave areas such as the legs, knees and elbows feeling smoother. It can be particularly useful when the skin feels rough or flaky, provided it is done gently.

The technique is also quick. A few minutes before showering can be enough, after which you can wash away the loosened skin cells and apply a body moisturiser. However, dry brushing should not replace moisturising, especially if your skin tends to become dry.
Some people also enjoy the sensation of brushing the skin. The friction can temporarily increase blood flow near the skin’s surface, which may leave the area looking slightly red or feeling warm. This effect is short-lived and should not be confused with treatment for circulation problems.

The claims surrounding dry brushing are less convincing. It is frequently promoted as a way to detox the body, reduce cellulite or improve lymphatic drainage. There is not enough evidence to support these claims. Dry brushing may temporarily make the skin look smoother, but it does not remove cellulite or toxins from the body.
How you brush matters. Applying excessive pressure can irritate the skin and damage its protective barrier. Use light, controlled strokes and stop if the skin becomes painful, scratched or persistently red. There is no benefit to brushing harder in an attempt to get better results.
Dry brushing should also be avoided over sunburn, cuts, wounds, rashes or irritated skin. Anyone with a skin condition that causes inflammation or sensitivity should check with a healthcare professional before adding physical exfoliation to their routine.

Daily brushing is not necessary. Start with occasional sessions and adjust according to how your skin responds. If your skin becomes dry, sore or irritated, reduce the frequency or stop altogether.
For those who tolerate physical exfoliation well, dry brushing can be a straightforward addition to body care. Its value lies in what it can realistically offer: removing surface dead skin and helping rough areas feel smoother, without the exaggerated detox and cellulite claims often attached to the practice.

How Often Should You Really Moisturise Your Lips
If you find yourself reaching for lip balm every hour, you may wonder whether you are applying it too often. There is no fixed number of applications that works for everyone. How often you need to moisturise your lips depends on their condition, the product you use and their exposure to factors such as sun, wind and dry air.
Dermatologists generally recommend applying a non-irritating lip balm when your lips feel dry and before bed, with more frequent application when conditions require it. For severely dry or cracked lips, a thicker ointment can form a stronger barrier against moisture loss.
So, How Often Is Enough?

If your lips are generally healthy and comfortable, you may only need lip balm when they feel dry, with an application before bed if they tend to become dry overnight. If they become dry during the day, reapply whenever needed, particularly after eating, drinking or wiping the product away.
Your routine should also change when you are spending extended periods outdoors. Sun protection is a separate part of lip care, so use a lip product with broad-spectrum SPF 30 or higher during the day. When using an SPF lip product outdoors, reapply about every two hours and after eating, drinking or activities that remove it.
Weather can also affect how often you need lip balm. Dry air, wind and cold conditions can increase moisture loss, so you may need to reapply more frequently. In particularly dry conditions, use your balm as often as needed, provided the product is not irritating your lips.
If Your Lip Balm Is Not Helping

If you are constantly reapplying lip balm but your lips remain flaky, sore or tight, the problem may not be that you need more of it. The formula itself could be irritating your lips.
Fragrance, flavouring, menthol, camphor and eucalyptus can irritate already-chapped lips in some people. Persistent burning, stinging or tingling can indicate irritation, so stop using a product that causes these reactions.
For dry or cracked lips, fragrance-free products with moisturising and occlusive ingredients are generally a better choice. Ingredients such as petrolatum, mineral oil, glycerin, dimethicone, ceramides and shea butter can help reduce moisture loss. Ointments can be particularly useful because they form a stronger barrier than lighter products.
Do You Need to Moisturise Overnight?

It can help, particularly if your lips tend to feel dry when you wake up. Applying a thicker, fragrance-free ointment before bed allows it to remain on the lips for several hours without being removed by eating or drinking.
This is also a practical time to use a richer product because you do not have to consider how it looks under lipstick or gloss.
Avoid Licking or Picking Your Lips

Repeatedly licking your lips can make dryness worse. Saliva may temporarily make them feel wet, but as it evaporates, it can leave the lips drier and more irritated. Picking or biting peeling skin can also cause further damage and delay healing.
While adequate hydration is important for overall health, persistent chapping is not necessarily caused by drinking too little water. External irritation, allergies, weather and certain products can all play a role.
If your lips remain cracked, scaly or painful despite consistent care, see a doctor or dermatologist. Seek medical advice sooner if they are bleeding significantly, becoming swollen or showing signs of infection.
The best approach is simple: use a non-irritating moisturiser when your lips need it, protect them from the sun and change products if you develop irritation. There is no need to follow a strict number of applications. Your lips and the conditions around you are better guides.
