Is Special Skincare Necessary After Red Light Therapy? Sun Protection, Moisturizing & More

Red light therapy is a gentle, non-invasive treatment, but post-session skincare can play a key role in maximizing results and protecting your skin. Here’s what you need to know:

1. Do You Need Sun Protection After Red Light Therapy?

While red light therapy doesn’t increase your skin’s sensitivity to UV rays (unlike treatments like chemical peels or retinoids), it’s still important to protect your skin—especially if you’re going outside shortly after treatment.
✅ Best Practice: Apply a broad-spectrum sunscreen with SPF 30 or higher to shield your skin from environmental damage and UV exposure.

2. Should You Moisturize After Red Light Therapy?

Yes—while RLT doesn’t typically dry the skin, keeping it hydrated can support healing and enhance the anti-aging or acne-reducing benefits of red light.
✅ Best Practice: Use a lightweight, hydrating moisturizer (preferably fragrance-free and non-comedogenic) to maintain skin barrier function and comfort.

3. Skincare Ingredients to Avoid Immediately After RLT

If your skin feels a little warm or reactive post-treatment, avoid applying potent actives like:
🚫 Retinoids
🚫 Alpha hydroxy acids (AHAs)
🚫 Beta hydroxy acids (BHAs)

Stick to gentle cleansers and soothing ingredients like hyaluronic acid, aloe vera, or niacinamide.

4. Is a Post-Treatment Skincare Routine Essential?

Not strictly, but a simplified, barrier-friendly routine can boost your therapy results over time and prevent irritation. Think: cleanse → treat (RLT) → moisturize → protect (if daytime).

Conclusion:
Special skincare after red light therapy isn’t mandatory, but applying sunscreen and a gentle moisturizer helps protect and enhance results. Skip harsh actives post-session if your skin feels sensitive. With consistent care, your skin will thank you!
