Company profile
researched Aug 2026Sincerely Yours is a direct-to-consumer skincare brand offering a small line of products aimed at developing and sensitive skin. Its catalog centers on a four-step routine — a hydrating cleanser (Kindly Clean), a soothing serum mist (Hit Refresh), a daily moisturizer (So Soft) and a mineral SPF 30 sunscreen (Sunny Side Up) — priced between roughly $22 and $28 per item, alongside a hydrating gloss balm (Sugarcoat Gloss Balm, $16) in Sheer Vanilla and Bubbleberry, a whipped clay mask and multi-product bundles such as The Fresh Starter Set, The Essentials and The Sweet Tooth Set, which are sold at discounts of up to about 20%.
The brand positions products as derm-developed, non-irritating, non-comedogenic and safe for sensitive skin, formulated without retinols, dyes, drying alcohols, sulfates, parabens, phthalates, PPG, formaldehyde, mineral oil, petrolatum or EDTA. A proprietary complex intended to hydrate, replenish and support the skin barrier is applied across the line, and products carry an internal "Signed Off" standard. The company's site also states that every purchase funds programs supporting the next generation, and it consolidates order shipments to reduce environmental impact. Site materials identify Salish Matter as a co-founder.
