Frequently Asked Questions

What is SQT® Spongilla Spicule?

1. SQT® Spongilla Spicules are a kind of siliceous bio microneedle that is extracted from the freshwater sponge.

2. It can be seen as powder by our eyes, and as sharp rod crystal or blunt bone needle under the microscope. Spongilla spicules are generally 200-250um in length and around 10um in diameter.

3. SQT® Spongilla Spicules are the core product of Sunshine Bio-Tech. Hunan Sunshine Bio-Tech Co.Ltd. is the pioneer of hydrolysed sponge purification and extraction, with 8 years of dedicated R&D and production, we deeply polish each bio microneedle to provide the highest quality spongilla spicules for the cosmetic industry.

Why do we choose spongilla Lacustris for SQT

Spongilla Lacustris is a freshwater sponge common in Europe. Sponge spicules are structural components functioning as a “skeleton” and defense system against predators and consisting of calcium carbonate, silica, and Chitin.

Spongilla Lacustris spicule extract is a multifunctional skincare ingredient that comprises all benefits of its natural components. Fine particles are used as an abrasive for mechanical exfoliation or dermabrasion, which polishes and eliminates old, pigmented, and dead cells from the skin surface, exposing a fresher, clearer, and radiant appearance.

Chitin is a long-chain polysaccharide consisting of glucose units, the second most abundant natural polymer after cellulose with similar characteristics. Spongilla Lacustris spicule contains α-chitin. It provides flexibility and strength to spicules and insect exoskeletons. It is not soluble in water, but its derivative chitosan is water-soluble and widely used in skin care applications.


Chitin is a perfect texturizing and bulking agent that provides a rich and soft feel. It has similar properties to keratin and is used in hair care formulations for brittle or damaged hair. In addition, thanks to natural antibacterial action against Streptococcus and other bacteria, Chitin is an ideal ingredient for preparations against acne and other skin infections.

In addition, it protects skin from UV exposure, moisturizes and improves water-retention ability (especially in combination with glucans), and binds another active ingredient assisting in the delivery and enhancing the formula’s stability. Spongilla Lacustris spicule extract is a natural, sage, and renewable ingredient to preserve the skin’s beauty and radiant glow.

Are the spicules ethically sourced through sustainability?

Sponges are live creatures and are important to the ecosystem and oceans.
Spongilla spicules have been famous for centuries and have been known for their use in skincare dating back to the 18th century in Europe. Sponge Spicules are sourced from the freshwater sponge in Lake Dongjang in China

Spicules sourced are completely natural, vegan, 100% ecological and at the same time unique in preparation using nano biological spicules.

Spicules are a hydrolyte of the purest organism in the world.  So far they have grown more than 10,000 types.

Sponge Spicules are a sustainable development, with no damage to the economy
Hunan sunshine biotech owns ISO series certification.(ISO9001, ISO14001, and ISO 45001) which are available upon request.

We also strictly abide by laws and government standards when researching and producing sponge raw materials.

How does the SQT® treatment work

In just 5 Minutes, 3 -5 million natural siliceous microneedles are directly introduced into the dermis layer of the skin through hand massage to promote skin metabolism and stimulate collagen regeneration. There is no bleeding, no anaesthesia, and no skin breakage. The treatment shortens the skin cycle from 28 days to 7 days by activation of the basal skin cells, and achieves natural, safe, and
effective physical rejuvenation.

Spongilla spicules are an effective modality of skin resurfacing and provide a natural alternative approach to microdermabrasion and dermabrasion, chemical peels (glycolic acid, Jessner’s, phenol and trichloroacetic acid peels), CO laser resurfacing and Erbium laser peels to correct visual facial defects such as hyperpigmentation of various etiology, fine wrinkles, Sun damage, Superficial Scars, comedones, enlarged pores, and facial rejuvenation.

Upon massaging Spongilla spicules into the skin, the spicules mechanically separate the epidermal layers and reduce keratinocyte cohesion, thereby increasing stratum corneum sloughing and sebum plug and loose keratinocyte removal.

What is the downtime?

Flaking or peeling can be expected on day 3-5 depending on the aesthetician’s level of penetration and the clients current skin condition. Not everyone will peel from treatment, and this does not mean it is not working, rather that the area is regenerating at a faster rate.

Spongilla spicules will not be absorbed but they can last in the skin for up to 48~72 hours. After 48 -72 hours they will be discharged with the stratum corneum that has fallen off.
Compared with a traditional metal microneedle, the procedure is much easier and the risk of infection is greatly reduced.

SQT vs Herbal Peels

The SQT treatment is totally different from the peeling of algae.

Algae powder or Spirulina powder is an unpurified powder, which contains a lot of plankton, dead branches or fallen leaves, and other impurities. It is a gray, gray-green, or brown powder with a fishy smell. There are a lot of broken needles, mostly used for Exfoliating.  The ingredients cannot stimulate the basal layer and cannot be compounded into other products as a single ingredient.

With seriously exceeded microbes and heavy metals, algae peel patients are easily prone to skin allergies, inflammation, infections, and other damages.  SQT Bio Microneedling needles are a far more superior treatment with 99% pure needles working on the INSIDE layer of skin to activate the basal skin cell.  The SQT principle is mostly through needles.  Each gram of sponge spicules contains 3-5 million fine needles that penetrate the skin by pressing to open skin channels, absorb ingredients, and remove excess oil / promote skin microcirculation.

Allergies and Adverse Reactions

Microneedling, regardless of the specific device used (roller, machine or SQT biological microneedling) is a relatively safe procedure with minimal adverse effects, however, the procedure is not limited to, expected erythema, pain, edema, and temporary skin irritation.

We advise that clinicians and patients be informed about the adverse side effects associated with microneedling so that the risk of preventable complications can be reduced or avoided.

SQT is an extremely safe procedure. However, if you are prone to allergies it’s always best to consult with your GP before undertaking any treatment. Any microneedling treatment can cause a histamine reaction which usually occurs on day 3 and lasts for 1-2 days.
Treatment is resolved with anti-histamine medication however clients must be aware of the potential downtime this may cause and plan treatment around any occasions or special events where makeup is needed.
