The publicly documented history of DeceMars can be traced back to 2017. A United States trademark record shows that Shanghai Boning Plastic Industry Co., Ltd. filed for the DECEMARS mark on 10 December 2017, covering products including false eyelashes, eyelash cosmetics, eyelash adhesives, eyebrow cosmetics, false nails and nail-care products [2].

The same trademark record lists 9 December 2017 as the first-use date for the goods covered by the registration [2].

The original US trademark was registered in 2018, suggesting that DeceMars had established a commercial presence in the eyelash and cosmetics category by that period [2].

More recently, another DECEMARS trademark application was filed in the United States in September 2025 for false eyelashes, eyelash cosmetics, eyelash adhesives, nail varnish, nail polish, varnish removers and false nails. The corresponding registration was recorded in April 2026 [4].

This indicates that the brand has continued maintaining and expanding its trademark protection rather than being merely a short-lived product label.

DeceMars is associated with Shanghai Boning Plastic Industry Co., Ltd. The company’s name appears both on the brand’s own website and in trademark records [1].

The company’s publicly listed contact address is:

2nd Floor, Building 16, Caohejing Water and Muyuan
No. 199 Guangfulin East Road
Songjiang District, Shanghai, China

The DeceMars website lists Connie as a contact person and provides an email address and telephone number for business inquiries [1].

Available public information does not provide sufficient evidence to describe Shanghai Boning as a large multinational cosmetics corporation. Based on available records, it is more accurately characterised as a Chinese company behind a specialised beauty and lash brand.

Eyelash extensions

Eyelash extensions are the core of the DeceMars product range.

The official product catalogue includes several designs, including:

• YY-shaped lashes
• W-shaped lashes
• 3D W-shaped lashes
• 4D W-shaped lashes
• 5D W-shaped lashes
• 6D W-shaped lashes
• Y-shaped / split-tip lashes
• Individual eyelash extensions
• Ellipse flat lashes
• Blossom / auto-flowering lashes
• Super-soft ellipse flat lashes

These products are designed around different lash-fan structures and visual-volume effects rather than simply offering conventional individual extension fibres [1].

For example, the brand markets a 1’S Blossom Eyelash Extension Auto-flowering Lash, demonstrating its emphasis on products intended to simplify or accelerate the creation of volume-style lash sets [1].

YY, Y and W configurations

A recognisable characteristic of the DeceMars catalogue is its use of multi-tip and preconfigured lash structures.

Instead of requiring a lash technician to construct every volume fan manually from individual fibres, products such as W-, Y- and blossom-style lashes provide multiple fibres arranged into a particular configuration.

This makes DeceMars particularly relevant to the professional lash-extension market, where application speed, consistency and the final volume effect are important considerations.

Flat and ellipse lashes

DeceMars also offers ellipse flat eyelash extensions and super-soft versions [1].

Flat or ellipse-style extensions differ structurally from traditional round lash fibres and are commonly used when a technician wants a darker lash-line appearance while maintaining a relatively lightweight extension.

False eyelashes and other cosmetics

The DeceMars trademark portfolio is broader than extensions alone.

Its registered or applied-for goods include:

• False eyelashes
• Cosmetic preparations for eyelashes
• Adhesives for false eyelashes
• False nails
• Nail polish
• Nail varnish
• Nail-care products
• Nail-art stickers
• Eyebrow pencils/cosmetics [2]

However, eyelashes remain the most visible and strongly represented part of its current product catalogue.

DeceMars occupies a professional lash and beauty-supply position rather than the traditional mass-market makeup-brand model.

Its website is structured primarily as a product catalogue and inquiry-oriented business site rather than as a consumer lifestyle or e-commerce platform. The site’s featured products are overwhelmingly eyelash-extension products [1].

This positioning makes the brand particularly relevant to:

• Lash technicians
• Eyelash-extension salons
• Beauty schools and trainers
• Professional beauty distributors
• Lash artists
• Individual consumers who purchase professional lash-extension supplies

The brand’s presence in specialist beauty retailers also supports this professional-market positioning. For example, Brazilian beauty retailers list DeceMars products under eyelash-extension categories, including Y, W and 5D/6D volume products [3].

The brand is associated with Shanghai, China, through Shanghai Boning Plastic Industry Co., Ltd. [1].

It would be premature, however, to state from available public material that every DeceMars product is necessarily manufactured at a particular factory or facility. The public website identifies the company and its Shanghai address but does not provide a detailed manufacturing-facility profile.

Likewise, there is insufficient public evidence to assign DeceMars a particular manufacturing scale, annual production volume, employee count or revenue figure.

Although DeceMars originates from China, evidence exists of its products appearing in overseas professional beauty markets.

For example, DeceMars products are sold by beauty retailers in Brazil, where the catalogue includes multiple lash-extension configurations [3].

The brand has also pursued trademark protection outside China. A Malaysian intellectual-property publication lists DeceMars under Shanghai Boning Plastic Industry Co., Ltd. for Class 3 cosmetic goods, including false eyelashes, eyelash adhesives and nail products.

There are therefore indications of an international distribution and export orientation, although publicly available sources do not establish a definitive list of all countries in which DeceMars officially operates.

Trademark records provide some of the clearest information about the brand.

United States

The DECEMARS mark was filed by Shanghai Boning Plastic Industry Co., Ltd. in 2017 and registered in 2018. The original goods included false eyelashes, eyelash cosmetics, eyelash adhesives and several nail and eyebrow products [2].

A subsequent US filing was made in 2025, covering a similar but somewhat streamlined group of beauty products. The mark was registered on the Principal Register in April 2026 according to the available trademark record [4].

Indonesia

An Indonesian intellectual-property publication also records DeceMars in Class 3 in connection with goods such as false eyelashes, nail polish, false nails, eyebrow pencils, eyelash adhesive, eyelash cosmetics, nail-care preparations and nail-art stickers.

These records demonstrate that DECEMARS/DeceMars has been formally protected as a commercial trademark in multiple jurisdictions.

Based on its catalogue, the DeceMars product philosophy centres on lash-volume construction and application convenience.

Rather than focusing mainly on mascara, eyeliner or general makeup, the company concentrates on the specialised technical side of eyelash enhancement.

The product naming itself reflects this progression:

Y → W → 3D → 4D → 5D → 6D → Blossom → Flat/Ellipse

This sequence represents different approaches to creating fuller, more dimensional lash effects.

The brand’s official slogan, “Keep your lash as beautiful as your soul!”, reinforces its beauty-focused identity [1].

Within the broader lash-extension industry, DeceMars is best understood as a specialist product brand rather than a large general cosmetics company.

Its differentiation appears to come from:

1. Specialised lash designs — particularly YY, Y, W and multi-dimensional configurations.
2. Volume-oriented products — 3D through 6D designs are prominently represented.
3. Premade/structured lash concepts — products such as Blossom and W-shaped extensions are intended to facilitate fan creation.
4. Professional orientation — the catalogue and contact-oriented website are consistent with a B2B/professional beauty-supply model.
5. International trademark activity — the brand has protected its name in multiple markets [2].

DeceMars does not have the same level of publicly available corporate information as major international beauty corporations.

Publicly accessible sources provide reasonably good evidence for:

• Brand name
• Trademark owner
• Product categories
• Product names
• Shanghai business/contact information
• Trademark history
• International trademark activity

However, reliable public figures are not substantiated for:

• Annual revenue
• Number of employees
• Annual production volume
• Exact factory locations
• Global market share
• Founder biography
• Detailed corporate history
• Official list of distributors worldwide
• Confirmed celebrity/influencer partnerships

Consequently, claims about DeceMars being a particular “market leader,” “largest manufacturer,” or having a specific global market share should be treated cautiously unless supported by additional documentation.

The brand maintains an official website at decemarsofficial.com, where its product catalogue and company contact information are presented [1].
