Skinfluencer Hype vs Reality: Which Viral Skincare Trends Are Worth Your Money?

Scroll through TikTok or Instagram for ten minutes and you'll see a new fix for dry skin, breakouts, puffy eyes or "glass skin". Viral skincare trends spread faster than ever. Some are genuinely useful, some are overhyped, and a few can leave your skin worse off. Before you spend your money, you deserve a straight answer.

We're upfront about our interest here: Curalene sells petroleum jelly, lip balm, glycerin soap and body cream, so some of the trends below overlap with our products. We've kept this honest. Where a trend has little evidence behind it, we say so.

Why viral skincare trends spread so quickly

Short videos reward dramatic before-and-afters. A 15-second clip can't show the slow, steady results that skincare usually delivers, and many creators are paid to promote products. Research on social media backs this up. One 2022 analysis reported a 46% rise in TikTok videos mentioning petrolatum between 2021 and 2022, showing how quickly a single ingredient can go from bathroom cabinet to trending topic.

Before you try something new, check for three warning signs. Be wary of promises of permanent change within days, "detox" or "miracle" language, and advice that doesn't mention who the product is unsuitable for. Credible advice usually includes caveats.

Slugging: the viral trend with the strongest evidence

Slugging means applying a thin layer of petroleum jelly as the final step of your evening routine. The petroleum jelly acts as an occlusive, which means it seals in the moisture from the products underneath it.

Dermatologists are more positive about slugging than about most viral trends. Clinicians writing for Dermatology Times describe it as one of the few social media skincare trends with genuine evidence behind it, provided the person is the right candidate. It is most useful for dry, sensitised or barrier-compromised skin. A 2024 review in the Journal of the American Academy of Dermatology covered petroleum jelly's long history and safety record, which supports its use on dry skin.

The caveats matter, though. The American Academy of Dermatology advises people with acne-prone skin to avoid putting petroleum jelly on their face, as it can contribute to breakouts for some people. Avoid slugging if you have open wounds, an infection, or sunburn, since a thick layer can trap heat.

If you want to try it, use only a pea-sized amount on clean, moisturised skin. For a full step-by-step, read our guide to what slugging is and how to add it to your routine.

If your lips are the main problem, you don't need to slug your whole face. A lip balm for dry skin in UK is easier to reapply during the day and simpler to fit into a routine.

Verdict: Worth trying for dry, sensitive skin, especially during winter. Skip it if your skin is oily or acne-prone.

Skin cycling: the routine dermatologists actually back

Skin cycling is a four-night routine coined by New York dermatologist Dr Whitney Bowe. It works like this:

  1. Night one: A chemical exfoliant
  2. Night two: A retinoid (such as retinol)
  3. Nights three and four: Rest, with gentle cleansing and a hydrating moisturiser

The logic is sound. Exfoliants and retinoids are powerful, and using several every night can irritate your skin and damage its barrier. The rest nights give your skin time to recover.

Dermatologists say the four-night schedule is a useful framework rather than a strict rule. Adjust it to how your skin responds. Some people can tolerate more active nights, and others need fewer. Also remember that skin cycling is an evening routine. Sunscreen should still go on every morning, because UV exposure doesn't take a rest day.

Speak to your GP or pharmacist before starting a retinoid if you are pregnant, trying to conceive, or using prescription treatments. If you're new to skincare, you don't need every product in the cycle. Start with a gentle cleanser, a moisturiser and one active.

Verdict: Worth it if you use active ingredients and want to reduce irritation. A good, flexible framework for a trending skincare routine UK built around your skin.

Gua sha and jade rollers: a relaxing ritual, not a face-sculpting miracle

Gua sha and jade rollers are some of the most viral facial tools. The promise is a sharper jawline and a lifted look, but the evidence is more modest.

A 2022 systematic review in the Journal of Cosmetic Dermatology found plausible mechanisms for improved circulation and lymphatic drainage, but limited evidence for lasting benefits. A 2025 randomised controlled trial compared facial rollers and gua sha over eight weeks, yet dermatologists still say there is no good evidence for permanent jawline or contour changes. US dermatologist Dr Jane Yoo has described the effect as a real but temporary de-puffing, which fades within hours.

If you enjoy the ritual, it's a pleasant way to wind down or start the morning. Use light pressure over a facial oil or serum so the tool glides rather than drags. Avoid dragging the tool across active breakouts, and keep sessions short. If you notice broken capillaries, stop, since added pressure can make visible veins more obvious.

Basic tools are inexpensive. Don't pay a premium for claims of permanent sculpting.

Verdict: Worth trying as a relaxing, de-puffing ritual. Not a substitute for a proper routine or medical treatment.

Glycerin soap and moisturiser: the trends that never went out of fashion

Some of the most reliable skincare isn't viral at all. Simple, well-formulated products do the job without the hype.

For cleansing, a glycerin soap bar in UK is a simple, budget-friendly choice for many people. Glycerin is a humectant, which means it helps draw moisture into the skin, so a glycerin-based soap can feel gentler on dry skin than harsher bar soaps. If your skin is very sensitive or reactive, a fragrance-free, soap-free cleanser may suit you better, and a dermatologist or pharmacist can recommend one.

For moisture, the best product is the one you'll use every day. For dry skin, look for a rich, fragrance-free cream that you can apply after washing while your skin is still slightly damp. If you're shopping for a best moisturiser for dry skin UK, check the label for fragrance and irritating additives if your skin reacts easily.

Verdict: Consistent, simple basics beat trend-led products almost every time.

How to try a viral trend safely

Introduce one new product at a time, and wait about two weeks before adding another. This makes it much easier to work out what is helping and what is causing irritation.

Patch-test new products before using them on your whole face. Apply a small amount to your inner arm or behind your ear for 48 hours. Stop straight away if you notice stinging, burning, swelling or a rash.

Be careful about layering several strong actives, such as an exfoliant, a retinoid and vitamin C, at the same time. A pharmacist on the high street can check your routine for free and flag any potential clashes.

See your GP or a dermatologist if you have persistent acne, eczema, or any change in a mole or skin patch. No skincare product replaces proper medical advice.

Frequently asked questions

Is slugging safe for UK winters?

For most people with dry or sensitive skin, yes. Cold, damp weather and central heating can strip moisture from the skin, so an occlusive layer at night can help. Stop if you notice irritation, and avoid it if you have oily or acne-prone skin.

Can petroleum jelly cause spots?

It can for some people. Petroleum jelly is generally considered non-comedogenic, but dermatologists advise caution for acne-prone skin, as a thick occlusive layer may trap oil and contribute to breakouts for some people. Patch-test first.

Does gua sha really work on the face?

It can temporarily reduce puffiness, and many people find it relaxing. There is no good evidence that it permanently slims the jaw or changes your facial structure.

What is skin cycling, and is it safe for beginners?

Skin cycling is a four-night routine that alternates an exfoliant and a retinoid with rest nights. It's a good starting point, but if you are new to retinoids, begin slowly, and speak to a pharmacist or GP first if you are pregnant or using prescription treatments.

Are expensive viral skincare products worth it?

Not usually. Many of the most effective basics are simple and affordable. Price is not a reliable sign of quality, so check the ingredients, the claims, and whether independent evidence supports them.

Can I use a glycerin soap bar on my face?

Many people with normal or dry skin use a gentle glycerin soap bar on their face. If your skin is very sensitive, reactive or acne-prone, a fragrance-free, soap-free cleanser may suit you better.

How long does it take to see skincare results?

Most products need at least four to six weeks of consistent use to show a visible difference. Be wary of anything promising overnight results.

The bottom line

Viral skincare trends aren't all hype, but they're rarely a magic fix. Slugging has the strongest support for dry skin, skin cycling is a sensible framework for using actives, and gua sha is a pleasant ritual rather than a sculpting tool. The most reliable routine is still a simple one that you can stick to.
