Influencer-led brand ONE/SIZE by Patrick Starrr has officially landed at Boots UK, bringing its high-performance primers and setting essentials to British consumers. Known for sweatproof, waterproof formulas designed for all skin types, the brand has built a loyal following through products that prioritise longevity without compromising skin comfort.
Leading the launch is the brand’s viral hero, On ’Til Dawn Mattifying Waterproof Setting Spray. Designed for extreme wear, the fine aerosol mist locks makeup in place for up to 16 hours, delivering waterproof, sweatproof and transferproof performance. The weightless formula helps control oil with witch hazel, while green tea extract visibly blurs pores for a smooth, airbrushed matte finish.

Also spotlighted is the Secure The Sweat Waterproof Mattifying Primer, an aluminium-free, clinically effective primer that controls oil and shine for up to 12 hours. Powered by plant-based ingredients including bamboo marrow powder and sage extract, it absorbs excess sweat while extending makeup wear and refining the look of pores.

Rounding out the hero lineup is Ultimate Blurring Setting Powder, offering up to 24-hour shine control with a soft-focus, flashback-free finish. Performance powder microspheres and surface-treated pigments deliver a lightweight, sweatproof veil that mattifies, smooths texture and locks makeup in place. The powder is available in seven shades, including new brightening tones.
Additional ONE/SIZE products now available at Boots include Powder Melt Glass Skin Setting Spray, B12 Base Thinner, Bouclé Silk Airbrushed Finishing Powder, and Luminous Vitamin Pearl Boosting Serum,
