CYSTOSEIRA BALEARICA EXTRACT.

Valuable / SKIN CONDITIONING

Cystoseira Balearica Extract, sourced from brown algae, is a versatile ingredient offering comprehensive skin benefits. It functions as a potent antioxidant and anti-inflammatory agent, actively diminishing oxidative stress and calming irritation. Additionally, it supports skin conditioning, aids in anti-aging processes, and contributes to a more even skin tone.

Science

Mechanism of Action

This extract acts as a robust antioxidant by directly neutralizing free radicals, specifically hydroxyl (OH) and nitric oxide (NO) radicals, which helps mitigate oxidative stress and may prevent damaging Fenton reactions. Its anti-inflammatory capabilities stem from its ability to abate oxidative stress and inhibit the production of pro-inflammatory cytokines such as IL-1α and IL-6, as well as crucial inflammatory mediators like NO production, cyclooxygenase-2 (COX-2), and inducible NO synthase (iNOS) gene expression. Potential anti-aging effects include counteracting collagenase and hyaluronidase activities to preserve dermal integrity and enhance cell survival against UV-induced toxicity. Furthermore, it demonstrates anti-tyrosinase activity, which may help address uneven pigmentation, and acts as a hygroscopic skin-conditioning agent, promoting revitalization, re-mineralization, and cell renewal for improved smoothness and suppleness.

Key findings

  1. 01 In vitro studies showed a significant reduction in intracellular reactive oxygen species (ROS) production in H2O2-stimulated macrophages and fibroblasts, with complete reduction achieved at 50 µg/mL and partial at 10 µg/mL.
  2. 02 It effectively inhibited LPS-induced inflammatory mediators, including nitric oxide production, IL-1α, IL-6, cyclooxygenase-2 (COX-2), and inducible NO synthase (iNOS) gene expression, within the 10 µg/mL to 50 µg/mL range in vitro.
  3. 03 Direct radical scavenging activity was quantified, with EC50 values of 392-454 µg/mL for hydroxyl (OH) radicals and 546-1293 µg/mL for nitric oxide (NO) radicals in vitro.
  4. 04 An animal maximization test applying a cream containing a related Cystoseira extract at 0.0023% showed no sensitization.

Dusting Analysis

Not commonly dusted

Precise human topical efficacy concentrations are not defined in the available research, making it difficult to assess if this ingredient is commonly 'dusted' in formulations or to establish an effective dusting threshold.

Stability

Polyphenols within algae extracts are susceptible to thermal degradation above 60°C and photo-oxidation from UV light. Optimal stability is maintained through mild extraction conditions, such as stirring at 30°C in the dark.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

While considered safe for cosmetic use, potential impurities like arsenic may be present; thus, good manufacturing practices (GMP) are crucial for monitoring and limiting these. Although a specific maximum concentration for Cystoseira Balearica Extract isn't explicitly defined, related brown algae extracts have been safely tested in humans up to 75% without sensitization.
