Laser hair removal is a revolutionary solution for long-term hair reduction. It’s safe, effective, and increasingly popular for those who are tired of shaving, waxing, or tweezing. However, like any cosmetic procedure, it’s not one-size-fits-all. Certain factors—particularly medications and sun exposure—can significantly impact the safety and results of your treatment.
I’m here to break down why these two factors are so critical, how they interact with laser technology, and what you need to know before booking your next session. And then of course, I will touch on how to enjoy the warmer months responsibly while still caring for your skin.
Why Do Contraindications Matter?
A contraindication is essentially a specific situation where a treatment may not be safe or advisable. In the context of laser hair removal, contraindications can lead to:
- Skin burns
- Hyperpigmentation or hypopigmentation
- Excessive irritation
- Prolonged healing or scarring
- Reduced effectiveness of the treatment
Two of the most common—and often overlooked—contraindications are certain medications and sun exposure. Let’s explore these in detail.
Medications That Interfere with Laser Hair Removal
Many clients are surprised to learn that some of their everyday medications can directly impact laser hair removal outcomes. Some may increase photosensitivity, while others may affect the skin’s healing process or make it more vulnerable to laser-induced irritation.
- Photosensitizing Medications
Photosensitizing drugs make your skin more sensitive to light, including the concentrated light energy used in laser treatments. This can increase the risk of burns, rashes, or pigmentation issues.
Common photosensitizing medications include:
- Antibiotics – Especially tetracyclines (e.g., doxycycline, minocycline) and fluoroquinolones (e.g., ciprofloxacin).
- Retinoids – Both topical and oral forms (e.g., tretinoin, isotretinoin/Accutane).
- NSAIDs – Ibuprofen, naproxen, and other anti-inflammatory drugs.
- Antidepressants – Some SSRIs and tricyclics.
- Birth Control Pills – Some hormonal contraceptives can cause increased sensitivity.
Before any laser treatment, always provide a full list of medications (prescription, over-the-counter, or herbal). If you’re taking a photosensitizing medication, I may recommend postponing treatment or proceeding with caution using an adjusted setting.
- Accutane (Isotretinoin)
Isotretinoin is particularly problematic because it affects the skin’s healing ability and increases sensitivity. Clients should wait at least 6 months after completing a course of isotretinoin before considering laser hair removal to avoid complications such as scarring or delayed healing.
- Blood Thinners and Corticosteroids
These can interfere with the body’s natural response to laser treatment. Blood thinners may increase the risk of bruising or bleeding, while corticosteroids may thin the skin, making it more susceptible to damage.
Sun Exposure: The Double-Edged Sword
While we all crave that golden summer glow, sun exposure before and after laser hair removal can be a significant risk factor. Here’s why:
Pre-Treatment Sun Exposure
Excess sun exposure before a laser session—whether natural, from tanning beds or from self-tanners—can:
- Increase melanin levels in the skin, which raises the risk of burns.
- Make it harder for the laser to distinguish between hair and skin pigment, reducing treatment efficacy.
- Lead to uneven results or post-inflammatory hyperpigmentation (PIH).
Ideal Practice: Avoid sun exposure and tanning for at least 7-10 days before your laser session. Always use a broad-spectrum SPF 50+ if you’re outdoors.
Post-Treatment Sun Exposure
Your skin is more vulnerable to UV rays after laser hair removal. It needs time to heal and regenerate without added stress. Immediate sun exposure post-treatment can cause:
- Burning
- Hyperpigmentation or dark spots
- Blistering in severe cases
Ideal Practice: Avoid direct sunlight on the treated area for at least 7 days post-treatment, and use physical barriers like clothing or wide-brimmed hats in addition to sunscreen.
Laser Hair Removal in Warmer Seasons: Yes, You Can!
Despite the warnings about sun exposure, laser hair removal can be done safely in the warmer months—you just need to plan and protect.
Here’s how to make it work:
- Schedule strategically. Plan your sessions well ahead of vacations or extended sun exposure.
- Protect your skin. Use mineral-based sunscreens, wear protective clothing, and avoid peak sun hours (10 am–2 pm).
- Hydrate and nourish. Keep your skin in peak condition with moisturizers and aftercare products recommended by your technician.
My Final Thought: Enjoy the Sun—Responsibly
