Red Light Therapy for Skin After 45: What It Can and Can't Do for Your Face
Quick summary
Red light therapy shines low-level red and near-infrared light on the skin. Controlled trials suggest it may modestly improve fine lines, roughness and skin feel over several weeks of regular sessions. It does not lift sagging skin, and results fade if you stop.
Clinic devices are more powerful than home devices, and most of the research used clinic-style equipment. It is generally low risk, but you need eye protection and should check first if you take medicines that make skin sensitive to light.
At Genova Skincare we sell a home device that includes red LED, so we have tried to keep this guide honest about what light can and cannot do. Results vary from person to person.
What is red light therapy, and why are women over 45 trying it?
At Genova Skincare, we are often asked whether red light therapy is worth it, and it is searched about 27,000 times a month in Australia. LED masks and wands are everywhere, and many women in their late 40s and 50s want to know if the glow is real or just good marketing.
Red light therapy, also called LED therapy or photobiomodulation, uses light-emitting diodes (LEDs) to shine red light onto the skin. Many devices also use near-infrared light, which you cannot see and which reaches a little deeper. The trials below used red light at about 633 nm and near-infrared at about 830 nm.
It is not a laser and it does not heat or wound the skin. That is why there is no downtime, and also why the changes it makes are gentle.
How red light therapy works on mature skin after 45
A review by Hamblin in AIMS Biophysics explains the leading theory. Light is absorbed by an enzyme in the mitochondria, the energy centres of skin cells. This appears to boost cell energy and calm inflammation, which may help the cells that make collagen.
That matters after menopause. A 2024 review by See and Chan in Medicine Today notes that a large share of skin collagen is lost in the first five years after menopause, with a slower loss after that. Red light will not replace that collagen, but it may give skin a small nudge in the right direction.
You may have read that NASA invented LED skincare. The accurate version is that LEDs were developed for NASA plant-growth experiments, and NASA-funded research, reported by Whelan and colleagues, later tested them for wound healing.
Does red light therapy work for skin rejuvenation? What the research says
The evidence is real but modest, and most of it comes from clinic-style equipment.
- Wunsch and Matuschka, 2014. In a controlled trial in Photomedicine and Laser Surgery, adults had red or broad-spectrum light twice a week for about 15 weeks. Compared with an untreated group, they had smoother skin, higher collagen density on ultrasound, and better-looking fine lines in blinded photo reviews.
- Lee and colleagues, 2007. A split-face, placebo-controlled trial in the Journal of Photochemistry and Photobiology B tested 633 nm red light, 830 nm near-infrared, or both, twice a week for four weeks. Wrinkles improved more on the treated side than on the placebo side, and biopsies showed more collagen.
- Mineroff and colleagues, 2024. A review in the Journal of the American Academy of Dermatology described red and near-infrared light as a noninvasive option with a good safety record for skin rejuvenation, while noting that standard treatment settings still need more research.
The American Academy of Dermatology notes that the red light offered in clinics is more powerful than at-home devices, that it is not a one-off treatment, and that not everyone sees results.
Red light therapy options for your face after 45 compared
Prices and power vary widely. This is a general guide, not a product review.
| Option | Typical use | Strength | Worth knowing |
|---|---|---|---|
| In-clinic LED panel | Course of sessions, often weekly | Highest | Closest to the trial settings; cost adds up |
| Home LED face mask | About 10 minutes, several times a week | Lower | Hands-free; quality and output vary |
| Handheld LED wand | A few minutes daily | Lower, small area | Easy to target areas; slower to cover the face |
| Genova Ion Applicator | Under 2 minutes, with serum or cream | Low (combined device) | Red LED with ion and vibration modes; not a replacement for a mask or clinic |

Pros and cons of red light therapy after 45
Pros:
- Non-invasive, painless and no downtime
- Controlled trials show modest gains in fine lines and texture
- Generally low risk when used as directed
- Can be combined with a normal skincare routine
Cons:
- Changes are subtle and take weeks
- Home devices are weaker than those used in most studies
- Results fade if you stop
- Does not lift sagging skin or restore lost volume
Red light therapy vs retinoids and sunscreen for menopausal skin
It helps to see where red light sits alongside the basics. Daily sunscreen protects the collagen you still have, and it has the strongest long-term evidence for slowing visible ageing. Retinoids have decades of research behind them for fine lines, although they can irritate dry, thinning skin after menopause.
Red light is best thought of as an add-on. It suits women who cannot tolerate retinoids, or who want a gentle extra step. It does not replace sunscreen, and it works best on top of a steady routine rather than instead of one.

Red light therapy safety: who should check first after 45
Red light therapy is generally considered low risk, but a few precautions matter.
- Protect your eyes. The AAD advises wearing the eye protection the instructions recommend, not ordinary sunglasses.
- Check your medicines. If a medicine makes your skin more sensitive to light, the AAD says red light may not be recommended. Ask your pharmacist.
- Tell your practitioner about light-sensitive conditions. ARPANSA, Australia's radiation safety agency, advises mentioning conditions such as lupus or epilepsy before light treatments.
- Watch for pigment changes. The AAD notes darker skin tones can develop dark patches.
ARPANSA also notes there are no specific restrictions on who can deliver LED treatments in Australia, so ask about training and the device before booking a clinic course.
Where the Genova Ion Applicator fits for skin after 45
If you want a small amount of red LED as part of a quick daily routine, Genova Ion Applicator is one option. It is a handheld device that combines red LED with ion and vibration modes, used with a Genova serum or cream in under two minutes.
It is designed mainly to help your skincare feel like it absorbs better, with red LED as one part of that. It is lower powered than an LED mask or a clinic panel, and it was not the device used in the studies above. We do not quote supplier test figures, because they are not independent studies.
Red LED, ion and vibration modes, used with your Genova serum or cream in under two minutes. 30 day money back trial.
What it is not
Genova Ion Applicator is a cosmetic device. It is not a medical device, it does not treat acne, rosacea or any skin condition, and it does not lift sagging skin. Do not use it if you have a pacemaker or implanted electronic device, are pregnant, or have broken or flaring skin, and avoid the eye area.
Who red light therapy suits after 45, and who it does not
It may suit you if you want a gentle, low-risk addition to your routine for fine lines and texture, and you are happy to use it regularly for several weeks.
It may not suit you if your main concern is sagging or volume loss, you take light-sensitising medicines, you have a light-sensitive condition, or you want fast, dramatic change.
How to use red light therapy at home after 45: step by step
- Check your medicines and conditions. Ask your pharmacist or GP if unsure.
- Read the device instructions. Session times and distances differ between devices.
- Cleanse and dry your skin. Remove makeup and sunscreen first.
- Protect your eyes. Use the goggles supplied, or close your eyes and keep the device away from them.
- Keep sessions short and regular. Most studies used sessions a couple of times a week for one to four months.
- Follow with your usual serum and moisturiser.
- Wear SPF 50+ every morning. Light therapy does not replace sun protection.
- Take photos every four weeks. Use the same light and angle to judge change fairly.
Realistic expectations
In trials, changes showed after roughly one to four months of regular sessions. Expect softer texture and slightly smoother fine lines, not a lifted face.
No LED device reverses ageing, and effects fade if you stop. Results vary from person to person.
Red light therapy questions women over 45 ask
How often should you use red light on your face?
Follow your device instructions. Studies mostly used sessions two or more times a week over one to four months.
Are there any disadvantages of red light therapy?
Results are modest and slow, home devices are weaker, and you need eye protection. It may not suit you if you take light-sensitising medicines.
Can I do red light therapy at home?
Yes. Home masks and handheld devices are widely sold, but they are lower powered than clinic devices.
Will red light therapy tighten saggy skin?
No. It may improve fine lines and texture, but it does not lift loose skin or jowls.
Where should you not put red light therapy?
Avoid shining it directly into your eyes, and avoid broken or irritated skin. Check with your GP before using it over any spot that is changing.
Does red light therapy age your skin?
Red and near-infrared LED light is not ultraviolet light, which is what causes sun damage. You still need daily sunscreen.
Red light therapy is one of the gentler, lower-risk options for skin after 45, with modest but real evidence behind it. Keep your expectations realistic, protect your eyes, and pair it with the basics: daily SPF and a good moisturiser.
