Can You Use Red Light Therapy with Tretinoin?

Introduction: Understanding Red Light Therapy and Tretinoin

Red light therapy and tretinoin are two popular skin care therapies that make the skin tone and texture better, fight the signs of aging such as wrinkles and fine lines, and repair sun damage.  They share the same objective, but operate and are utilized differently.

Tretinoin is a retinoid topical drug mostly applied in dermatologic and cosmetic treatments. Red light therapy, on the other hand, involves exposing the skin to low-level red or near-infrared light and is applied not only in skincare but also in medicine and fitness for various reasons, such as wound healing and muscle recovery.

Red light therapy acts on the cellular level through the use of designated red and near-infrared light wavelengths that are absorbed through the skin to stimulate natural healing processes. Red light therapy benefits by stimulating collagen growth, lowering inflammation, and enhancing the overall tone of the skin.

Tretinoin, a vitamin A derivative, is used as a topical cream or gel. It stimulates cell turnover, suppresses dark spots, treats acne, and decreases fine lines.

In this article, we will discuss whether you can use red light therapy and tretinoin together, the advantages of using them combined, and what benefits they have in general.

How Red Light Therapy Works for Skin Health

Red light therapy, or photobiomodulation or low-level laser therapy, is a non-invasive, drug-free form of therapy that employs precise wavelengths of red and near infrared light to penetrate the skin and trigger the body's natural healing processes.

This treatment stimulates the mitochondria, the energy-producing structures within cells, to generate more energy in the form of adenosine triphosphate (ATP). Increased ATP facilitates multiple cellular functions to allow for quicker repair, regeneration, and healing of cells in the skin and healthy cell turnover.

Red light therapy increases blood flow, which enhances oxygen and nutrient delivery to the cells in the skin. Increased blood circulation also aids natural detoxification by assisting in clearing waste and toxins from the cells.

Also, red light therapy enhances the texture and appearance of the skin by increasing the level of collagen and elastin production—two proteins that play a key role in keeping the skin tight, smooth, and young. It also decreases inflammation by preventing the production of pro-inflammatory cytokines, which reduces redness, swelling, and puffiness on the face.

Scientific Research Supporting the Use of Red Light Therapy for Skin Health

Red light therapy has become a leading player in cosmetics and dermatology, with an increased number of scientific studies confirming its effectiveness in enhancing skin health. Some studies have established that red light therapy triggers higher energy production, promotes more blood flow, and increases the formation of collagen and elastin. These results help in decreasing wrinkles, fine lines, sun damage, tan, and acne, thereby smoothing, firming, and making the skin look younger.

Clinical Trials Demonstrating the Effectiveness of Red Light Therapy for Skin Health

Study 1: Evaluation of Red Light and Polychromatic Light Therapy for Full-Body Skin Rejuvenation and Collagen Enhancement.

Objective

The aim of this research was to determine whether two new styles of light therapy equipment are safe and effective for use on broad body areas. These devices apply a soft, non-heating (non-thermal) form of light to enhance the appearance and feel of the skin. The researchers were curious about whether treating the skin with a broader spectrum of wavelengths (colors) of light would be more effective in repairing skin than the conventional narrow-band lights, such as lasers and LEDs.

Results

Of 136 individuals who participated, those who received the light therapy experienced noticeable improvement in their skin. Their skin was and felt healthier, less rough, and exhibited more collagen (protein which keeps skin tight). These outcomes were verified by various means such as professional photo analysis, ultrasound, and skin surface measurements. Individuals who did not get the treatment did not experience the same improvements.

Conclusion

The broader range of light didn't give better results than red light alone, but both new types of light therapy were safe and helped improve skin appearance and boost collagen. These light sources may be a good option for non-invasive skin rejuvenation treatments.

Study 2: Procedure for Red Light LED Photobiomodulation Treatment for Facial Skin Rejuvenation.

Objective

The purpose of this research was to assess how effectively red LED light therapy (through the Skin Light Dior x Lucibel mask) is in rejuvenating facial skin. The mask projects cold red light at 630 nm wavelength and was applied for 12 minutes, twice a week, for 3 months.

Results

The subjects, 20 healthy Caucasian females, exhibited consistent and perceptible improvements in their skin over time. These included fewer wrinkles around the eyes, tighter and more elastic skin, a clearer facial outline, smoother and more evenly toned skin, smaller pores, and improved oil control. Measurements were made with a variety of scientific tools, and the participants themselves also reported great satisfaction with the treatment.

Conclusion

Red LED light therapy (photobiomodulation) was shown to effectively counteract apparent signs of skin aging and promote general skin health. Effects persisted even a month after the therapy ceased, indicating long-term effects on both the function and structure of the skin.

What Is Tretinoin and How Does It Affect the Skin?

All-trans retinoic acid or tretinoin is a broad-spectrum vitamin A-derived topical medication. It is most often used to treat cosmetic and dermatologic conditions such as acne, wrinkles, dark spots, and sunspots. Tretinoin is a group of medications known as retinoids, which exert their action by increasing cell turnover and promoting the growth of new skin cells.

The drug is typically used topically in the form of gel or cream since it has been proven to work. When used, tretinoin triggers the exfoliation of damaged and dead skin cells for the creation of new and healthy ones. It thus improves the renewal of the skin as well as unclogs pores.

Tretinoin also tones down irregular skin texture and reduces the appearance of wrinkles and pigmentation with time. Apart from that, it also promotes collagen production in the skin, which contributes to a smoother, younger, and firmer appearance.

But some may develop side effects from taking this cream. Common side effects of topical tretinoin are peeling, dryness, redness, and sun sensitivity. These side effects are usually localized in the skin and resolve with the passage of time and proper skin care.

Therefore, if you must utilize this retinoid family member, it is strongly recommended to use it under the supervision of a dermatologist.

Can You Use Red Light Therapy with Tretinoin?

Yes, you can use red light therapy and tretinoin together because both will help you achieve smoother, tighter, and younger-looking skin. Although both are great and powerful skincare treatments, they work differently and offer distinct benefits.

Red light therapy uses certain red and near-infrared wavelengths of light to penetrate deep into the skin. It enhances cellular energy production, lessens inflammation, and stimulates collagen and elastin production for increased firmness and smoothness of the skin. The therapy works internally to improve the tone and texture of the skin at the cellular level.

In contrast, tretinoin acts mainly on the skin surface. It stimulates cell turnover, keeps pores open, and triggers collagen production, making it useful in the management of acne, wrinkles, and photodamage.

Red light therapy has no side effects, but tretinoin induces skin thinning, most notably to light and heat. Application of red light treatment shortly after application of tretinoin can result in redness, dryness, or irritation.

In order to use both treatments safely together, it's advisable to apply them at different times of the day. For instance, if you are applying tretinoin at night, use red light therapy in the morning or vice versa. Also, don't forget to apply sunscreen when going outside, as tretinoin makes the skin sensitive to the sun. Finally, you should moisturize regularly to prevent dryness of the skin and ensure that both treatments reap the best out of them.

Potential Benefits of Combining Red Light Therapy and Tretinoin

When you use red light therapy together with tretinoin, you can achieve the best results and obtain smooth, healthy, firm, and young skin sooner. Each treatment has its advantages, yet they both are extremely effective in improving skin tone and texture. However, it is important to use them at the right time and follow instructions to avoid side effects or irritation.

Here are the key benefits of using red light therapy and tretinoin together:

Quick Skin Renewal

Tretinoin accelerates skin cell turnover by killing old and aged cells and replacing them with new cells, and red light therapy improves healing and regeneration at a quicker rate. They both help in eliminating damaged skin more efficiently and stimulate healthy new skin growth.

Enhanced Collagen Production

Both tretinoin and red light therapy cause collagen production. Tretinoin does so by stimulating cell turnover, while red light therapy increases the energy in cells, leading to improved collagen production. This pair smoothes out fine lines, increases elasticity, and creates a firmer complexion.

Improved Skin Texture and Tone

Red light therapy penetrates deep within tissues to improve the skin texture from within by boosting blood circulation and oxygenation. Simultaneously, tretinoin works externally to smooth out uneven surfaces and lighten dark spots. Together, they provide a more even and radiant skin tone.

Reduce Inflammation and Redness

Red light therapy is a proven anti-inflammatory treatment. By suppressing the release of pro-inflammatory cytokines, it suppresses redness, itchiness, and inflammation—most notably those tretinoin side effects.

Accelerated Visible Effects

Both red light treatment and tretinoin are able to accelerate the repair of your skin. Combined, they suppress wrinkles, fine lines, and dark spots more aggressively, resulting in smoother, firmer, and younger skin in less time.

Risks and Precautions When Using Both Treatments Together

Tretinoin and red light therapy combined can do wonders for your skin, but you have to be careful. Both are strong treatments, and misuse can result in pain or irritation. Here's what you need to know to stay safe:

Your Skin Might Get Extra Sensitive

Tretinoin makes your skin sensitive to heat and light. Red light therapy too soon after tretinoin will make your skin dry, red, or irritated.

Use Them at Different Times

Don't use red light therapy immediately after applying tretinoin. A better routine is the application of red light therapy in the morning and tretinoin at night. This provides your skin with a bit of time to heal in between.

Start Gradually

If you're new to either one, don't rush. Start with gentle use—maybe a low-strength tretinoin and short red light sessions. Let your skin adjust.

Wear Sunscreen Every Day

Tretinoin makes your skin more likely to burn in the sun. Even if you're mostly indoors, always apply sunscreen during the day to protect your skin.

Keep Your Skin Moisturized

Both of these treatments dry out your skin. Keep your skin smooth and healthy with a good moisturizer.

Pay Attention to How Your Skin Reacts

If lots of redness, itching, and peeling happen, you're probably using too much. Decrease the treatments you use and consult a dermatologist if necessary.

Stay Away from Harsh Skincare Products

When either of these treatments is being used, avoid products containing alcohol, exfoliants, or harsh acids unless under the direction of a physician. These will increase irritation. 

By using tretinoin and red light therapy gently and adhering to these easy-to-follow tips, both may be used safely and their benefits enjoyed with minimal, if any, side effects.

Selecting the Appropriate Red Light Therapy Device for Safe and Effective Home Use

Similarly to tretinoin, you can also do red light therapy at home—you just need a good device. Most devices available on the market aren't efficient or safe for use at home, so you really do need to be selective. If you are seeking a device for carrying out red light therapy along with tretinoin at home, consider the following:

Specific Wavelengths

The device must emit red light between 610–670 nm and near-infrared light between 810–1064 nm. These precise wavelengths enable cells to heal themselves, promote blood flow, reduce inflammation, and begin producing collagen and elastin.

FDA-Approved and Science-Based

Choose a device that has been tested in a lab and is FDA-approved. FDA approval indicates that the device is effective and safe to use in the home. 

Proper Power Output

The machine should be capable of delivering power that will penetrate light into deep skin tissues without obstruction.

Adjustable Intensity

Opt for a device with variable intensity controls so you can switch the light intensity according to your requirements and comfort.

Portability

Having a portable machine is always convenient, allowing you to take it along wherever you go and maintain your regular sessions.
