Hydrocolloid technology
What is hydrocolloid technology ?
Hydrocolloid (HDC) technology stems from advancements in wound dressings. In just a few decades, it has revolutionized wound care by promoting the healing of superficial, slightly weeping wounds such as blisters, grazes, and burns.
Hydrocolloids form a viscous gel upon contact with water. They consist of a complex network of polymers that are both hydrophilic (water-absorbing) and hydrophobic (insoluble). Thus, they lock in moisture within a flexible, flow-resistant structure and absorb fluids seeping from the wound, while forming a protective layer over the injured area.¹
These properties create favorable conditions for the healing of the lesion and the skin repair process.
Today, hydrocolloid technology is also used in dressings for blister care and in patches for treating pimples on acne-prone skin.
How do hydrocolloid blister plasters work?
Hydrocolloid dressings for the treatment of blisters are flexible, robust but discreet dressings designed to relieve pain and accelerate the healing of blisters.
Hydrocolloid technology allows the formation of a skin-regenerating gel upon contact with exudate, promoting skin repair in a moist environment. The dressing also protects the damaged and highly sensitive area from friction and contaminants such as bacteria and dust. Once the blister has healed, it detaches on its own.
What are the advantages of hydrocolloid technology against blisters?
- A targeted action on the lightbulb, in complete discretion.
- Fast pain relief.
- Accelerated restoration of damaged skin.
- A protective barrier that effectively isolates the area and prevents pressure and friction that cause discomfort.
How do hydrocolloid patches for acne work?
Hydrocolloid patches for acne-prone skin are composed of:
- an inner layer that absorbs the contents of the pimple ;
- an outer layer that helps protect the area from impurities and external aggressors, while limiting friction and manipulation that could alter the skin's appearance.¹
These two complementary layers work in synergy. They absorb excess sebum and exudates, facilitate the repair of the skin's structure, and protect the blemish from external aggressors. Hydrocolloid technology can be combined with purifying active ingredients to optimize its effectiveness.
The blemish patch protects the skin from the discomfort caused by excessive manipulation: redness, visible marks, accentuated imperfections, delayed healing, etc. It treats the blemish while preserving the skin's integrity.
What are the advantages of hydrocolloid technology against pimples?
- Targeted action on the blemish, discreetly.
- Fast-acting, as soon as the blemish appears, reducing redness, size, and volume.²
- A protective barrier that prevents dirt and bacteria from worsening the blemish.
