Do at-home skin care devices replace a consistent skincare routine?

No device will do as much for your skin as consistently following a simple, optimized skincare routine. A good routine includes a gentle cleanser, a barrier-supporting moisturizer, daily sunscreen, an antioxidant serum in the morning, and a cell-turnover product at night — such as prescription tretinoin or a bakuchiol-based formula. At-home devices should be considered only after your foundational routine is solid.

How do you choose a good red light therapy device?

Device quality and irradiance matter significantly. You need to use the device as recommended by the manufacturer, since devices vary in irradiance and the time required to deliver a therapeutic dose of energy. Omnilux and Celluma are both well-designed options. Some devices — like the Dr. Dennis Gross and Theraface — may have irradiance levels that are too intense for more sensitive skin types.

Are there real skin benefits to using a dry sauna?

Saunas increase blood flow to the skin through vasodilation, which may support skin health and barrier function by delivering more oxygen and nutrients. Early research also suggests heat exposure may stimulate heat shock proteins involved in collagen remodeling. That said, the anti-aging skin benefits should not be overstated — people with rosacea or sensitive skin may find that excess heat worsens redness. Hydrate well, keep sessions reasonable in temperature and duration, and moisturize after to prevent over-drying.

Are high-frequency wands an effective acne treatment?

High-frequency wands generate ozone that may reduce acne-causing bacteria on the skin, but the evidence supporting them is minimal. We have many more proven acne treatments — including retinoids, benzoyl peroxide, salicylic acid, sulfur, hydrocolloid patches, and LED light therapy — that are more effective. These devices are relatively low risk if used correctly, but I would not expect dramatic results and do not recommend them.

A Dermatologist’s Guide to At-Home Skin Care Devices

Q: Which at-home skin care device has the strongest scientific evidence?

Red light therapy currently has the best combination of scientific evidence, safety, and visible results among at-home skin care devices. Low-level red and near-infrared light devices stimulate cellular energy production and reduce inflammation in the skin. With consistent use over weeks to months, studies suggest improvements in fine lines, redness, uneven pigmentation, acne, wound healing, and overall skin quality.

Q: Do microcurrent devices like NuFACE permanently tighten the face?

Microcurrent devices can temporarily lift and define the face, particularly around the cheeks and jawline, but they do not produce significant long-term tightening. You have to use them consistently to maintain the effect, and once you stop, the lifting fades fairly quickly. They can be useful before an event or photographs, but I would not recommend them as a long-term solution for sagging.

At-home skin care devices are everywhere. Some are helpful, many are not, and all are overhyped. None do as much for your skin as being consistent with your optimized skincare regimen.

Of all at-home skin care devices, red light therapy currently has the strongest combination of scientific evidence, safety and visible results. Most other devices provide either temporary cosmetic effects or minimal proven long-term benefit.

Your Skincare Routine Matters More Than Any Device

None of these devices will do as much for your skin as consistently following a simple, optimized skincare routine.

A good skincare routine includes:

A gentle face wash
A moisturizer that supports the skin barrier
Daily sunscreen
An antioxidant serum in the morning, like my Day Preventive Treatment
A cell turnover product at night, such as prescription tretinoin or my Night Repair Treatment with bakuchiol and glycolic acid.

If you need a refresher on how to build a perfect skincare routine, I have a blog dedicated to it here.

If you are already crushing your skincare regimen and ready to make things more complicated then let's move on to at home devices and see if any are worth your time and money.

Which At-Home Skin Care Devices Are Actually Worth It?

Once your skincare routine is optimized, some at-home devices may offer additional benefits. The problem is that the quality of evidence, safety and long-term results vary dramatically between categories.

Red Light Therapy

Red light therapy is currently the one category of at-home skin care device backed by the best combination of science, safety and visible results.

Low-level red and near-infrared light devices help stimulate cellular energy production and reduce inflammation in the skin.

With consistent use, studies suggest red light therapy can help improve:

Fine lines and wrinkles
Redness
Uneven pigmentation
Acne
Wound healing
Overall skin quality

The key is consistency and a well-made device. Most studies use treatments several times a week over months, not days. This is not an overnight fix, but many people notice their skin is calmer and healthier over time.

You need to use the device as recommended by the manufacturer as they vary in irradiance and the time required to deliver the dose of energy proven to benefit the skin.

In my research, both Omnilux and Celluma are well designed. In comparison, the Dr. Dennis Gross and Theraface irradiance may be too powerful for more sensitive skin.

For those wanting to understand more about red light, I have a blog dedicated to it here.

Facial Massage Devices

Facial massage tools can temporarily reduce puffiness by helping move fluid through the lymphatic system helping to make your face look more sculpted or defined temporarily.

These devices do not create long-term lifting or tightening, but they can temporarily improve puffiness and facial definition. I find them helpful in the morning after too much salt or booze to depuff my face.

I use the facial massage tool from Joanna Czech and the TheraFace. I find both helpful and easy to use.

Microcurrent Devices

Microcurrent devices like NuFACE and ZIIP use low-level electrical currents to stimulate facial muscles.

They are time consuming and for many the conductive gel can be irritating. I do not recommend them as a long term treatment for sagging. You have to use them consistently to maintain the effect, and once you stop, the lifting effect fades fairly quickly.

That said, they can temporarily lift and tighten the face, particularly around the cheeks and jawline, which can be helpful before an event or photos. This is a common treatment for celebrity facials before an award show.

High Frequency Wands

High frequency wands are often marketed as acne treatments because they generate ozone, which may help reduce acne-causing bacteria on the skin.

The problem is the evidence is minimal and we have so many proven acne treatments that are more effective, including

Retinoids
Benzoyl peroxide
Salicylic acid
Sulfur
Hydrocolloid patches
LED light therapy

These devices are relatively low risk if used correctly, but I would not expect dramatic changes and do not recommend them.

Mechanical Cleansing Brushes

Just stay away.

Mechanical cleansing devices can disrupt the skin barrier, worsen irritation and aggravate conditions like rosacea, eczema and acne. They also harbor bacteria.

Your hands work perfectly well and exfoliation is generally more effective when it is chemical, like retinoids or alpha hydroxy acids, rather than mechanical, like brushes or scrubs.

Dry Saunas

Dry saunas have become incredibly popular recently and unlike many wellness trends, there is some decent data supporting overall health benefits. Regular sauna use has been associated with improved circulation, stress reduction, better sleep and cardiovascular health.

From a skin perspective, saunas increase blood flow to the skin through vasodilation. This increased circulation may help support skin health, healing and barrier function by delivering more oxygen and nutrients to the skin.

Early research suggests heat exposure may stimulate heat shock proteins, which help cells repair stress and damage, and may play a role in collagen remodeling over time.

That said, I do not want to overstate the anti-aging benefits of saunas and there are many who cannot tolerate them. For some people, especially those with rosacea or sensitive skin, the excessive heat can worsen redness.

A few tips:

Keep sessions reasonable in temperature and length, especially when starting out
Hydrate well before and after
Wash sweat off and then moisturize after to prevent over drying out of the skin.
Skip if your skin is already feeling dried out or sensitive

As you often hear me say, great skin doesn’t come from doing more. It comes from doing the few things that work, and doing them consistently. I can help you identify what those things are, but you have to commit to them. Of these devices, the red light is the only one I regularly recommend for the skin and dry sauna for general health benefits.
