Treatment Pumps

Key Features of the Treatment Pump Range

Low-Dose Precision Dispensing

Treatment pumps are built for precision — delivering 0.2ml to 0.4ml per actuation depending on the SKU, significantly less than a standard lotion pump. This makes them the right dispensing format for concentrated formulations where a small, measured amount is both sufficient and desirable: actives-rich serums, facial oils, hair treatments, nail serums, scalp treatments and similar products where dose control reduces waste and improves the consumer application experience.

Broad Neck Size Range Including GL18

With neck sizes spanning 18/415, GL18, 20/400, 20/410 and 24/410, the range covers a wider variety of bottle formats than any other pump category in the BlueSky range. Notably, the GL18 neck size is a standard glass bottle thread — making treatment pumps in this finish directly compatible with narrow-neck glass bottles used in premium skincare, cosmeceutical and fragrance-adjacent packaging.

Smart Pump — Named Precision Dosing Format

The Smart Pump is a specific treatment pump format within the range, designed for very precise dose control. Available in 20/400 (0.2ml) and 24/410 (0.25ml/250mcl) neck sizes in black and white, it is suited to concentrated formulations where dose accuracy directly affects product performance or safety.

T-Clip Actuator Option

Selected 24/410 SKUs are available with a T-Clip actuator — a T-bar clip mechanism that holds the pump actuator in a lowered position for transit and retail display, preventing accidental dispensing. This differs from a lock-down or lock-up mechanism: the T-Clip is removed by the user before first use and is not replaced, making it suited to products where a tamper-evidence or first-use indicator is part of the pack brief.

Gloss Silver Collar Finish Options

Collar finish options — gloss silver — are available across GL18 and 24/410 neck sizes, relevant for premium skincare, serum and cosmeceutical brands where the treatment pump is visible and contributes to pack presentation.

Compatible with Aluminium, PET and Glass Bottles

Treatment pumps in this range are compatible with aluminium, PET and glass bottles — a broader material compatibility than most pump categories. The GL18 neck size specifically suits glass dropper bottles; 18/415, 20/410 and 24/410 sizes suit aluminium and PET formats. This makes the range relevant for brands across personal care, premium skincare and healthcare where bottle material varies by product line.

UK Stock on Core SKUs — Scheduled Supply Available

Key stocked SKUs are available for fast dispatch from UK stock. For production buyers who need forward supply certainty, BlueSky offers a scheduled order service — allowing you to lock in forward volumes against UK-held stock. Compatible bottles can be included in the same supply arrangement.

What is a Treatment Pump?

A treatment pump is a precision dispensing closure designed to deliver a small, controlled dose of liquid product per actuation — typically 0.2ml to 0.5ml, compared to 1–4ml for a standard lotion pump. The small dose output makes treatment pumps the right format for concentrated formulations, active ingredients and treatment-type products where a precise, measured amount per use is important for both efficacy and economy.

How does a treatment pump differ from a lotion pump?

The primary difference is dose output and the products they suit. A lotion pump delivers 1–4ml per stroke — appropriate for body lotions, hand soaps and larger-format personal care products. A treatment pump delivers 0.2ml–0.5ml per stroke — appropriate for concentrated serums, facial oils, actives-rich treatments and formulations where the dose is deliberately small. Treatment pumps are also commonly used with smaller, narrower bottles (30ml–100ml) typical in the skincare and cosmeceutical segment, while lotion pumps suit larger personal care formats.

What is the GL18 neck size?

GL18 is a standardised glass bottle neck thread — the designation comes from the European glass packaging standard. GL18 refers to an 18mm diameter neck thread commonly found on narrow-neck glass bottles such as glass dropper bottles used in premium skincare, serum, cosmeceutical and pharmaceutical-adjacent packaging. Treatment pumps in GL18 neck size are designed specifically for use with glass bottles using this thread standard, and are not interchangeable with plastic bottle neck sizes.

What is a T-Clip actuator?

A T-Clip is a T-bar mechanism fitted across the actuator of a treatment pump that physically prevents the pump from being pressed down during transit and retail display. Unlike a lock-up or lock-down mechanism, the T-Clip is a single-use feature — it is removed by the consumer before first use and not reattached. This makes it suited to products where a first-use indicator or transit security is required without the ongoing lock mechanism of a lock-up pump.

What is the Smart Pump?

The Smart Pump is a specific treatment pump design within the BlueSky range, engineered for precise, low-dose dispensing. Available in 20/400 at 0.2ml and 24/410 at 0.25ml (250mcl) output, it is suited to concentrated treatment formulations where dose accuracy is critical — including actives-rich serums, clinical skincare formulations and similar applications.

A buyer may choose a treatment pump because:

• the product is a concentrated serum, active treatment or precision-dose formulation
• the bottle is a narrow-neck glass (GL18) format
• the dose per actuation needs to be 0.5ml or less
• the pack requires a T-Clip transit security feature
• a gloss silver collar finish is required on a small-format skincare bottle
• UK stock and scheduled supply are important for production planning

Where Treatment Pumps Are Used

Facial Serums and Actives

Treatment pumps are the standard dispensing format for facial serums, vitamin C formulations, retinol treatments, hyaluronic acid serums and similar actives-rich skincare products. The low dose output — typically 0.2ml–0.4ml — is suited to concentrated formulations where a small amount per application is both sufficient and deliberate. Narrow-neck glass and PET bottle formats in this category suit the 18/415, GL18 and 20/410 neck sizes.

Facial and Body Oils

Facial oils, dry oils and treatment body oils — where a small, controlled amount is dispensed and massaged in — benefit from the precise, low-dose output of a treatment pump. Glass bottles are common in this category, making GL18 neck compatibility relevant.

Hair Treatments and Scalp Serums

Concentrated hair treatment oils, scalp serums and leave-in treatment products dispensed in small doses use treatment pumps to control application volume and reduce waste. The 24/410 and 20/410 neck sizes suit the bottle formats common in this category.

Nail Care

Nail serums, cuticle treatments and nail strengthening formulations dispensed in small, precise amounts use treatment pumps — particularly in smaller bottle formats.

Cosmeceutical and Clinical Skincare

Products positioned at the cosmeceutical or clinical skincare tier — where active ingredient concentration and dose precision are part of the product proposition — frequently use Smart Pump or precision treatment pump formats. These are also relevant for healthcare-adjacent skincare products where dose control has a functional rather than purely cosmetic significance.

Premium Personal Care

For premium personal care brands using glass or aluminium bottles in a narrower neck format, treatment pumps in GL18 or 18/415 provide the right dispensing format alongside a gloss silver collar option that supports premium pack aesthetics.

Contract Filling

For contract fillers handling premium skincare, serum and cosmeceutical briefs from brand owner clients, the treatment pump range covers the neck sizes and dose outputs most commonly specified in this segment. UK-held stock and scheduled ordering simplify supply planning for these higher-value, lower-volume production programmes.
