What red light therapy is
Red light therapy uses specific wavelengths of light — 550 nm, 650 nm and 800 nm — to support the skin’s natural healing process. It energizes cells, prompting them to perform their normal functions.
That description is deliberately modest, and the modesty is the point. Unlike laser hair removal or laser skin rejuvenation, red light therapy is not destroying or targeting anything. There is no heat damage to a follicle, no pigment being broken up. Light at these wavelengths is absorbed by the cells and supports the work they already do.
It is a comfortable treatment. You rest under the light; there is no numbing, no snap against the skin, and nothing to recover from afterwards.
What it may help with
Red light therapy may help calm inflammation, reduce temporary redness and support overall skin wellness. It may be recommended as a standalone service or as an add-on to another treatment when appropriate.
Read the word may as written. This is an area of aesthetics where claims routinely outrun the evidence, and you will find clinics and home devices attributing near-miraculous outcomes to red light. We are not going to do that here. What is offered is a comfortable, low-risk treatment that supports the skin’s own recovery, most usefully alongside something else.
Where it fits best: after something more demanding
The most sensible use of red light therapy in a practice like this one is as support for recovery. Treatments such as microneedling and laser skin rejuvenation work by provoking a healing response, and leave the skin temporarily red, warm and in the middle of that process.
Because red light therapy supports that same natural healing process and helps calm inflammation and temporary redness, it can be a natural companion to those treatments rather than a competitor to them. Whether it is appropriate for you, and whether it is better placed on the same day or at a separate appointment, depends on what was done and how your skin responded — which is a judgement made at the time, not a package sold in advance.
As a standalone appointment
It can also be booked on its own. The people for whom that makes most sense are those with skin that is easily provoked — skin that reacts, flushes and stays irritated — and who want something supportive rather than something aggressive.
If that is you, say so when you get in touch. A practice that puts reactive skin straight into an intensive treatment course has not listened.
What it will not do
It will not remove hair. It will not clear brown spots or sun damage — that is what laser skin rejuvenation addresses. It will not resurface texture or improve the appearance of scarring the way a series of microneedling treatments may. It is not a substitute for sunscreen or for a professional skincare routine, and it is not a treatment for a medical skin condition.
If what you want changed needs one of those other treatments, you will be told so rather than sold a course of light because it is pleasant and easy to deliver.
Before and after
There is no shaving to do beforehand and no preparation window to observe, but you should still disclose your medications, supplements and skincare products. Some medications increase light sensitivity, and that is relevant even for a gentle treatment.
Afterwards there is no downtime to plan around. General aftercare still applies if red light has been used alongside another treatment: avoid unnecessary heat, friction, irritating skincare products and sun exposure as directed, wear sunscreen, and follow the specific instructions you are given for whatever else was done that day.
How it is priced
Red light therapy is priced as a standalone appointment or as an add-on to another treatment, and the figure depends on which of those applies and how it fits your plan. It is not published on this site for that reason. What is published in full is the laser hair removal price list, where the price is fixed by treatment area.
If you are not sure whether red light therapy is worth adding to what you are already considering, ask at the consultation. The honest answer is sometimes no.
Common questions
What is red light therapy, and what are its benefits?
Red light therapy uses specific wavelengths of light (550 nm, 650 nm, 800 nm) to support the skin’s natural healing process. It energizes cells, prompting them to perform their normal functions. It may help calm inflammation, reduce temporary redness, and support overall skin wellness. It may be recommended as a standalone service or as an add-on to another treatment when appropriate.
Is there downtime, and what should I avoid after laser treatment?
Downtime varies according to the treatment performed. Temporary redness, warmth, mild swelling, or darkening of treated pigment may occur. Avoid unnecessary heat, friction, irritating skincare products, and sun exposure before and after as directed. Wear sunscreen and follow the specific aftercare instructions provided by your technician.
How do I know which treatment is right for my skin concerns?
You do not have to know which service to book. During your consultation, we will evaluate your skin, discuss your goals, and explain which treatment — or combination of treatments — is most appropriate. If your concern is outside our scope, we will recommend evaluation by an appropriate medical provider.
Do I need a consultation before treatment?
Yes. Your consultation allows us to evaluate your skin, review your medical history and medications, discuss your concerns, and determine whether treatment is appropriate for you. It also gives you an opportunity to ask questions and receive a customized treatment plan.
Ask whether it is worth adding
Celtic Lasers opens in Baton Rouge in fall 2026. Join the early list and ask about red light therapy directly — including whether it is likely to do anything useful for your skin, which is a question with a real answer either way.
