The pursuit of ageless beauty takes a revolutionary turn with probiotics, emerging as powerful allies in the fight against wrinkles, dryness, and photoaging. While time inevitably leaves its mark, harnessing the potential of the skin microbiome unlocks a treasure trove of anti-aging benefits.
Aging manifests in two primary forms. The first, Natural Aging, is driven by internal factors like genetics and telomere shortening, resulting in subtle lines and loss of skin elasticity. The second, photoaging, is the harsh hand of ultraviolet radiation accelerating skin aging. The latter contributes to wrinkles, pigmentation, and even skin cancer. This villain disrupts the skin’s microbiome, raises pH levels, and triggers harmful free radical production.
Combatting the effects of UV rays, probiotics offer a multi-pronged approach:
Hydration & Barrier Restoration: Dryness often plagues aging skin due to a weakened epidermal barrier. Probiotic strains like Streptococcus thermophilus S244 and Streptococcus salivarium spp. stimulate skin-hydrating enzymes, while oral probiotics like Bifidobacterium breve and Lactobacillus plantarum effectively reduce water loss and boost hydration.
According to a study, researchers found that Heat-Killed Lactobacillus L-137 (HK L-137) emerges as a promising agent for improving skin moisture retention by stimulating HA (hyaluronic acid) production by activating immune cells.
IFN-γ, a pro-inflammatory cytokine, plays a pivotal role in this process, collaborating with TNF-α, another pro-inflammatory cytokine, to orchestrate the upregulation of HA synthesis. This opens doors for future research exploring HK L-137’s potential in skincare and its contribution to maintaining healthy, hydrated skin.
Studies reveal that heat-inactivated Lactobacillus plantarum L-137 (HK L-137) effectively boosts skin cell hyaluronic acid production, a key molecule for plumpness and wrinkle reduction.
Ceramide Boost: Ceramides, vital components of the skin’s protective barrier, decline with age. Probiotic preparations like Streptococcus thermophilus and ultrasonic therapy can significantly increase ceramide levels, enhancing skin barrier function and elasticity.
Antioxidant Defense: Free radicals, the malicious byproducts of metabolism and environmental stressors, wreak havoc on skin cells, contributing to wrinkles and age spots. Probiotics like heat-killed Lactobacillus acidophilus KCCM12625P (AL) regulate reactive oxygen species (ROS) and matrix metalloproteinases (MMPs), both culprits in skin aging. Similarly, heat-killed Lactobacillus rhamnosus (RL) exhibits antioxidant and anti-melanin properties, promising for anti-aging and anti-photoaging cosmetics.
Collagen & Elastin Replenishment: Age depletes collagen and elastin, the crucial protein fibers providing the skin with a youthful bounce. Probiotics can support their production. Research suggests that combining β-Nicotinamide Mononucleotide (NMN) with Lactobacillus fermentum, TKSN041 enhances skin antioxidant enzyme levels and reduces UV-induced damage, paving the way for firmer, younger-looking skin.
Extracellular Vesicles: These tiny packages secreted by bacteria contain potent bioactive compounds contributing to skin health. Studies highlight the anti-aging properties of extracellular vesicles produced by L. plantarum, including inhibiting MMPs and elastase activity, improving elasticity, and even enhancing filaggrin production, all essential for maintaining a strong and supple barrier.
