This Works Deep Sleep Pillow Spray is the cult-favorite mist many insomniacs swear by for turning a restless bed into a lavender-cloud retreat. One or two pumps on the pillowcase lay down a naturally scented veil—no messy oils, no heavy perfumes—and the 2.5-ounce bottle is sized for both nightstand and carry-on.

Deep Dive

A Look into thisworks's deep sleep pillow spray

Born in a London beauty lab and tested on actual shift workers, Deep Sleep Pillow Spray has achieved near-legendary status: over nine million bottles sold and endless “can’t-sleep-without-it” social-media posts. The formula pairs three bedtime classics—lavender to quiet the limbic system, vetiver to ground racing thoughts, and chamomile to soften the blend—diluted into a fine mist that dries in seconds. No oils to stain linens, no glass to shatter if it topples off a hotel nightstand, just a discreet spritz that feels more like skincare than aromatherapy homework.

Ingredients & Extraction

Why the certifications matter

• COSMOS Natural or USDA Organic seals can confirm the botanicals were grown without synthetic pesticides.
  
  

• GC-MS batch reports prove the essential-oil portion is genuine plant distillate, not fragrance oil.
  
  

• Allergen-screen testing helps sensitive users spot potential irritants in leave-on fabric sprays.
  
  

Quick-look bullets

• Water-glycerin base with natural solubiliser
  
  

• Essential oils: lavender, vetiver, wild chamomile
  
  

• Preserved with phenoxyethanol for 24-month shelf life
  
  

• Cruelty-free; 99 % natural-ingredients claim

Lavender and vetiver are steam-distilled; wild chamomile arrives via gentle solvent extraction to preserve its sweet esters. These oils are emulsified with plant-derived polysorbate so they disperse evenly in water rather than floating in oily droplets. The mix is preserved with a trace of phenoxyethanol to keep microbes out of the bottle. The packaging lists the product as cruelty-free and 99 % natural, but there are no third-party organic or GC-MS badges, so users rely on This Works’ in-house testing and ISO-certified facility.

Scent Profile

First mist: a soft, herb-fresh lavender that feels airy rather than pungent. Within seconds vetiver adds an earthy hum, lending depth that keeps the blend from smelling like laundry detergent. As the fabric dries, a gentle chamomile sweetness surfaces—more apple-tea than floral—and stays detectable until morning for most sleepers.

• Top: Powder-fresh lavender sprig
  
  

• Heart: Dry vetiver grass, hint of warm soil
  
  

• Base: Honey-apple chamomile, whisper of hay
  
  

• Fabric longevity: ~6 h on cotton pillowcases

Brand Story & Purity

Founded in 2003 by former Vogue Beauty Director Kathy Phillips, This Works focuses on evidence-backed sleep and skin solutions. Every launch passes through a panel of real-world product testers, from new parents to emergency-room nurses, and the company funds small-scale clinical trials to validate claims like “fall asleep faster.” Products are blended in the UK, and batch numbers trace back to stability and microbiology reports kept on file for customer queries.

What Shoppers Say

Deep Sleep posts a 4.4-star average from more than 21 000 buyers. One reviewer writes, “Don't hesitate, just buy it!!! This spray has changed the game for me and I couldn't be more in love with it. I've used it for 10 days and it has helped me sleep so much better and feel good when I wake up. It might be one of the best things I've ever bought myself.” A handful of users say the aroma fades too quickly, especially on sateen fabrics, or that frequent flyers wish the plastic atomiser felt sturdier.

Quick-look bullets

• Praise: Calms quickly, travel-friendly, no oil stains
  
  

• Negatives: Scent may fade on slick fabrics; sprayer feels lightweight for price

How We Use It

Because the blend is already pillow-safe and pre-diluted, application couldn’t be simpler—yet the same bottle can play several roles in a bedtime routine.

Diffuser — Not for diffusers; the solubiliser and preservative can coat ultrasonic plates.

Topical — Lightly mist pulse points or the inner wrist for on-skin aroma; patch-test first if you have fragrance sensitivities.

Pillow Spray — Hold 6 in / 15 cm from fabric and spritz 2–3 times over the upper third of the pillowcase about five minutes before lying down.

Bath — Add 20 pumps (≈ ½ tsp / 2.5 mL) to warm water; emulsifier helps the oils disperse instead of floating.

Laundry — After the dryer stops, mist 3–4 sprays onto a clean cotton cloth, toss it into the drum, and tumble on air-fluff for five minutes to scent sleepwear.

Shelf‑Life & Storage

The water-based formula stays fresh for two years sealed and one year after opening. Keep the bottle upright below 77 °F (25 °C) and out of direct sunlight; discard if the liquid clouds or develops an alcohol-sharp edge.

Quick-look bullets

• Shelf life: 24 mo sealed, 12 mo opened
  
  

• Store ≤ 77 °F (25 °C), away from sun
  
  

• Spoilage cue: cloudy liquid or sharp alcohol smell

Price & Value

The 2.5 fl oz / 75 mL atomizer lists at USD 33.00, translating to about USD 13.20 per oz or USD 0.44 per mL. While pricier than a DIY linen mist, the cost includes a fine emulsion, dermatological testing, and a leak-proof travel bottle. One container typically covers several months of nightly spritzing, keeping overall spend reasonable.

Verdict

This Works Deep Sleep Pillow Spray earns its reputation as a fuss-free entry ticket to aroma-assisted slumber. A mid-tier price, lack of open lab data, and occasional spritzer issues clip the Evellon Oil Score to 8.1 / 10, yet the balanced scent, travel ease, and proven fan base make it a worthy staple for anyone who’d rather spritz than blend their way to dreamland.
