LE SÉRUM SUPPORTS INTIMATE SKIN ACROSS ALL LIFE PHASES
The Science
As estrogen naturally declines, the body produces less glycogen, hyaluronic acid, and collagen, key molecules involved in skin hydration, elasticity, and microbiome balance. Intimate skin can become thinner, drier, and more sensitive, with a weakened skin barrier that is more prone to irritation and discomfort.
How Le Sérum Helps
Our Hyaluronic Acid + Glycogen complex works to support the natural environment of intimate skin, while soothing botanicals including oat extract and aloe vera help calm dryness and sensitivity. Swiss-cultured plant stem cells support skin resilience and vitality, and Microflora Ferment helps maintain microbiome balance during hormonal transition.
As skin ages, the natural production of hyaluronic acid and collagen gradually declines. Intimate skin, which is already thinner and more hormonally sensitive than facial skin, can become less firm, less elastic, and more prone to dryness over time.
How Le Sérum Helps
Swiss-cultured plant stem cells support collagen and elastin pathways, promoting skin firmness and resilience over time. Our Hyaluronic Acid + Glycogen complex delivers sustained hydration, leaving skin visibly smoother, plumper, and more even-looking with continued use.

The Science
Certain medications, including isotretinoin, GLP-1s, and SSRIs, can contribute to dryness in skin tissue and mucous membranes, leading to increased sensitivity, discomfort, and a weakened skin barrier.
How Le Sérum Helps
Clinically shown to increase hydration by 200% within one hour, Le Sérum delivers immediate and lasting hydration to sensitive intimate skin. Aloe vera, oat extract, and our Hyaluronic Acid + Glycogen complex work together to soothe discomfort and help support the skin's natural moisture balance.

The Science
Hormonal fluctuations during and after pregnancy can affect skin elasticity, hydration levels, and microbiome balance. During the postpartum period, particularly while breastfeeding, reduced estrogen contributes to dryness, increased sensitivity, and a more vulnerable skin barrier.
How Le Sérum Helps
Our Biomimetic Renewal Complex®, Swiss-cultured plant stem cells, and Hyaluronic Acid + Glycogen work together to support skin barrier resilience during hormonal changes and deliver deep hydration to delicate skin. Microflora Ferment helps maintain microbiome balance of the external intimate skin, while soothing botanical extracts help ease dryness and sensitivity throughout recovery.

The Science
The intimate microbiome is dynamic and sensitive, influenced daily by hormones, stress, medications, friction, and product use. When this balance is disrupted, the skin barrier can weaken, increasing the likelihood of dryness, irritation, and discomfort.
How Le Sérum Helps
Fragrance-free, alcohol-free, and pH-compatible, Le Sérum is formulated to support rather than disrupt the intimate microbiome. Our Microflora Ferment, a prebiotic and postbiotic complex, helps support a Lactobacillus-favorable environment, promoting microbiome balance and barrier resilience with continued use.
90%
Women suffer imbalanced vaginal microbiomes
The Science
The intimate area is one of the body's most hormonally sensitive regions. Friction, inflammation, hormonal fluctuations, and environmental stressors can gradually overstimulate melanin production, contributing to uneven skin tone over time.
How Le Sérum Helps
Swiss-cultured plant stem cells support skin vitality and resilience, while our Biomimetic Renewal Complex® works to improve overall skin quality and tone. With continued use, Le Sérum helps support brighter, more even-looking intimate skin.
