Yes, SMILES is completely safe when used as directed. Our tape includes a small breathing hole that ensures airflow if needed – so if you need to cough, sneeze, or breathe through your mouth temporarily, you can. The gentle adhesive means you can easily remove the tape at any time, even while half-asleep.

Your body also has natural protective reflexes. If you experience any breathing difficulty, you'll automatically wake up and remove the tape long before there's any risk. It's impossible to ignore. If you're new to mouth taping, try wearing it for 20–30 minutes while awake first. This helps you feel comfortable before using it overnight. Most people find it surprisingly comfortable from the first night. If you have concerns about breathing issues, consult your healthcare provider.

SMILES gently keeps your lips closed while you sleep, encouraging nasal breathing instead of mouth breathing. This simple shift brings powerful benefits: breathing through your nose helps your body produce nitric oxide, which enhances oxygen delivery to every cell.

As a result, you experience deeper, more restorative sleep since your brain and body receive the oxygen they need. You’ll reach REM sleep more quickly and stay in it longer. Nasal breathing also naturally filters and humidifies the air, protecting your airways and preventing the dryness that often disrupts sleep.

Your nervous system stays calmer, lowering stress hormones that can cause restless nights and morning grogginess. The outcome? You fall asleep faster, enjoy more restful sleep, and wake up feeling genuinely refreshed. And with SMILES’ bioactive ingredients working overnight, your skin’s natural repair process is also supported. It’s the difference between simply sleeping and truly recovering.

Most people notice improvements in their sleep quality from the very first night — waking up more refreshed and experiencing less dryness in the mouth. Within 3–5 nights, it’s common to see reduced morning puffiness and feel more energized throughout the day.

After 2–3 weeks of consistent use, the real transformation takes shape. Your body adjusts to nasal breathing, resulting in deeper sleep, clearer skin, and even subtle jawline definition from correct mouth positioning. Many users also report sharper focus and less brain fog during this period.

By around day 30, you should experience the full benefits: consistently better sleep, visibly healthier skin from improved oxygen flow, and enhanced facial definition. The bioactive ingredients in SMILES aid this process by delivering nutrients that support your skin’s natural overnight repair cycle. While results vary depending on your breathing patterns and consistency of use, the improvements typically build over 2–3 months as nasal breathing becomes your natural sleep rhythm. For best results, use SMILES every night.

We’re so confident you’ll love the transformation that we provide a 30-day money-back guarantee. No results? No worries — get a full refund.

Many people with allergies find that mouth taping actually helps ease their symptoms over time. Nasal breathing naturally filters out allergens and irritants from the air, which can help reduce reactions and inflammation.

The small breathing hole in SMILES ensures you can still breathe comfortably while your body adjusts. If you’re dealing with mild congestion, you can usually continue using SMILES — nasal passages often clear once you begin breathing through your nose. If you’re feeling very congested or uncomfortable, simply skip that night and try again when breathing feels easier.

Most users notice that consistent use of SMILES improves their nasal breathing over time, making allergies and congestion less frequent. If you’re concerned, start gradually — try wearing it for short periods while awake to build comfort and confidence.

Many customers successfully use SMILES alongside their CPAP therapy. The tape helps keep the mouth closed during CPAP use, reducing air leaks and dry mouth — two common issues that can limit CPAP effectiveness. This combination often leads to more comfortable sleep and better overall therapy results.

That said, if you have sleep apnea or currently use CPAP, we recommend discussing SMILES with your sleep specialist first. They can guide you on the best approach for your individual needs. While many people find that mouth taping enhances their CPAP experience, it’s always safest to confirm with your doctor.

It depends on the type of sleep apnea. If you have obstructive sleep apnea (OSA), it’s important to consult your doctor first. Mouth taping is not a replacement for medical treatment. However, if your case is mild, or you’re already using a CPAP machine, SMILES can make a noticeable difference. By preventing air leaks from the mouth and encouraging proper nasal breathing, SMILES can help improve the effectiveness of CPAP therapy. Many users also report better sleep quality when combining the two.

For mild snoring or undiagnosed breathing issues, SMILES can be a helpful first step toward better rest. The bioactive ingredients support overall wellness while the tape encourages healthier breathing habits. Always consult your healthcare provider if you suspect you may have sleep apnea.

Please don’t. Using regular tape (like medical or duct tape) is unsafe for overnight facial use. It can damage delicate skin, trigger allergic reactions, or even cause breathing difficulties. These types of tape often contain harsh adhesives not designed for the face and may leave toxic residue on sensitive lip skin.

SMILES is made with medical-grade, hypoallergenic adhesive specifically designed and tested for safe overnight facial use. It features a small breathing hole for airflow, the ideal adhesive strength (secure but gentle), and a shape created for comfort. In addition, the bioactive formula in SMILES nourishes your skin while you sleep — something regular tape could never provide.

Your skin deserves more than hardware store solutions. SMILES is engineered for safety, comfort, and results. Don’t risk irritation, skin damage, or breathing issues just to save a few dollars.

Our promise is simple: try SMILES for 30 full nights. If you don’t notice better sleep, clearer skin, or overall improvement, just return the unused strips for a full refund. No questions asked, no hassle. Refunds are processed within 2–3 business days of receiving your return.

We’re able to offer this guarantee because more than 94% of women who try SMILES become repeat customers. We’re confident you’ll love how you feel (and look) after a month of improved breathing and skin support from our bioactive formula. The guarantee begins on your delivery date, giving you plenty of time to experience the full benefits.
