Quick Answer:
The viral “pad flashlight test” usually highlights how light passes through plastic layers and super-absorbent materials (SAP) found in many conventional pads. A glow or uneven look doesn’t automatically prove “toxins,” but it can signal synthetic components and a lack of ingredient transparency—one reason many people choose plant-based, fragrance-free pads.

What Is the Viral Pad Flashlight Test?

If you’ve scrolled through TikTok lately, you’ve probably seen people holding up their Always pads under a flashlight— shocked by what they’re seeing. The trend has sparked heated debates, with some users claiming the glow reveals “chemicals,” “plastic layers,” or “mystery ingredients.”

At Rif Care, we love when people start asking questions about what they’re using on their bodies — because that’s where change begins.

What Are Conventional Pads Made Of? 

Most mainstream pads — including brands like Always — are made primarily from plastic-derived materials. These can include:

• Polyethylene and polypropylene (used for the top and bottom layers)

• Super absorbent polymers (SAPs) that trap fluid

• Fragrances, adhesives, and dyes (for scent and color consistency)

• Ethanol, Petrol, and synthetic colors

Why Do Some Pads “Glow” Under a Flashlight?

When light shines through a pad, it can highlight synthetic components that reflect or scatter light, creating a glow or uneven appearance. What you’re seeing isn’t “magic” — it’s likely light interacting with plastic layers and super-absorbent materials commonly used in conventional pads.

While it’s impossible to determine the exact cause without laboratory testing, similar pads containing SAP can appear differently depending on manufacturing variation, material density, or moisture exposure. Environmental factors—like humidity in a bathroom—may also influence how these materials look under bright light.

Still, the larger question remains: do you want to use products made with petrochemical-based materials, solvents, or undisclosed additives in close contact with your body for an estimated seven years over a lifetime—the average amount of time a person menstruates?

(HONORABLE MENTION: this ingredient list is insane, how is it even legal?)

Why Ingredient Transparency Matters

Your skin — especially the vulva — is one of the most absorbent areas on the body. What’s in your pad matters. Many people were surprised to learn that U.S. regulations don’t require brands to disclose their pad ingredients. Even with all the things listed, there can be things missing. That’s why pads can contain dozens of undisclosed compounds — and why this flashlight trend has struck such a nerve.

When something is designed to be worn for hours at a time in an intimate area, ingredient transparency should be the bare minimum.

How Rif Care Is Different

At Rif, we’re proud to use biobased fibers and natural materials instead of plastics and synthetic absorbents. Our pads are:

• Made from plant-based fibers like organic hemp and cotton

• Free from plastic top sheets, dyes, and fragrances

• Designed for comfort, performance, and biodegradability

• While many conventional pads rely on superabsorbent polymers (SAPs), we don’t use them. We prioritize plant-based materials and will continue evaluating safer, truly biodegradable innovations as they emerge.

What to Look for When Choosing a Safer Pad

Not all pads are created equal. If you’re trying to reduce irritation, chemical exposure, or environmental impact, here’s a quick checklist to help you choose more intentionally:

✔ Fragrance-Free
Added scents are a common cause of irritation and allergic reactions. A safer pad should be free from perfumes and masking fragrances.

✔ Material Transparency
Brands should clearly disclose what their pads are made from. If ingredient lists are vague or missing entirely, that’s a red flag.

✔ Plant-Based or Natural Top Sheet
Look for pads made with organic cotton or hemp rather than plastic-based top layers. Natural fibers are typically more breathable and gentler on sensitive skin.

✔ No Chlorine Bleaching
Chlorine bleaching can leave behind trace chemical byproducts. Pads labeled “TCF” (totally chlorine-free) are a safer option.

✔ Minimal Synthetic Additives
Avoid unnecessary dyes, adhesives, or coatings designed solely for aesthetics. Simpler materials often mean fewer irritants.

✔ Breathability
Pads that allow airflow help reduce moisture buildup, odor, and discomfort—especially during long wear.

Choosing a safer pad isn’t about perfection—it’s about awareness. Small swaps can make a meaningful difference for your body over time.

Final Thoughts

We believe you shouldn’t need a flashlight to see what’s in your pad. Transparency should come standard.

The flashlight trend isn’t just a viral moment — it’s a wake-up call. People want to know what they’re using, what it’s made from, and how it impacts their health and the planet.
