A dropper instead of pills or capsules: a choice of authenticity
We do not seek to present our products as conventional medicines through dosage forms such as capsules or softgels. We embrace a plant-based, natural, and effective identity. The dropper allows for precise dosing and direct contact with the raw material; it preserves the bioavailability of the active ingredients and highlights the quality of our ingredients. We have chosen to prioritize the quality of our raw materials over the marketing of a useless and costly dosage form.

Clinical studies: vaginal mucosa, dry eyes, skin
Sea buckthorn oil and the vaginal mucosa (menopause)
- Participants / duration: 116 postmenopausal women; a randomized, double-blind study lasting 3 months, comparing 3 g/day of sea buckthorn oil with a placebo.
- What was measured:the integrity of the vaginal epithelium (the condition of the tissue) andthe vaginal health index (VHI).
- The results were clear: women taking sea buckthorn were 3.1 times more likely to improve mucosal integrity than those taking a placebo (OR 3.1; 95% CI 1.11–8.95). The VHI improved (+0.8), whereas it remained unchanged in the placebo group (−0.1).
- Key takeaway: When taken orally, sea buckthorn oil helped strengthen the vaginal lining in postmenopausal women within three months.

Sea buckthorn oil and dry eyes: stabilized tear film
- Participants / Duration: Adults during the cold season; a randomized, double-blind study lasting 3 months, comparing 2 g/day of sea buckthorn oil with a placebo.
- What was measured: tear film stability (as determined byosmolarity) and symptoms (redness, burning).
- Clear results: sea buckthorn slowed the increase in osmolarity ( more stable tear film) compared with placebo (p=0.04 in the ITT analysis; p=0.02 in the per-protocol analysis). Redness (ITT p=0.04) and burning (PP p=0.04) also decreased.
- Key takeaway: When taken orally, sea buckthorn oil helped stabilize tear production and alleviate certain symptoms of dry eyes within 3 months.

Omega-7 (palmitoleic acid): hydration and skin barrier
- Participants / Duration: Adults, randomized double-blind study, 12 weeks, oral supplementation with palmitoleic acid (omega-7).
- What was measured: skin hydration and transepidermal water loss (TEWL), as well as other instrumental parameters.
- Clear results: Compared to placebo,hydration increased and TEWL decreased significantly after 12 weeks (not all secondary parameters, such as elasticity, were statistically significant).
- Key takeaway:Omega-7 (palmitoleic acid, the key fatty acid in sea buckthorn pulp oil) improves the skin barrier andhydration over the course of several weeks.

Note on transparency: Dosages vary depending on the study (e.g., 2 g/day for dry eyes; 3 g/day for the vaginal mucosa). The key point is the consistent trend: when taken orally, sea buckthorn lipids—includingomega-7 —supporthydration and comfort of the mucous membranes and skin over 8 to 12 weeks (or longer).
FAQ
When will I start to feel the effects?
Many women report improved eye comfort within 3 to 4 weeks. The tear film becomes more stable over time, improving eye comfort. The skin appears more supple and better hydrated in about a month. Continue taking the supplement to maintain these results, and adjust the dosage according to the season and how you feel.
How can I relieve vaginal dryness naturally?
Practice gentle hygiene and wear cotton underwear. Use a suitable lubricant if needed. Take oral supplements containing high-quality sea buckthorn oil, with an adequate dose of omega-7 (270 to 360 mg/day). Stay hydrated, stay active, and limit your intake of tobacco and alcohol. If the discomfort persists, consult a healthcare professional.
Which omega fatty acid is best for vaginal dryness?
Omega-7 (palmitoleic acid) is the gold standard for treating vaginal dryness. It occurs naturally in sea buckthorn pulp oil and helps restore vaginal and vulvar comfort by providing hydration. Omega-3/6/9 fatty acids remain beneficial for overall lipid balance, but omega-7 is the most targeted for mucous membranes.
What are the benefits of sea buckthorn for the eyes?
When taken orally, sea buckthorn oil helps maintain the stability of the tear film thanks to its omega-7 fatty acids. Lutein and vitamin E provide additional photoprotection. Many users report less stinging and a reduction in dry eye symptoms over the course of several weeks.
What are the side effects of sea buckthorn oil?
Sea buckthorn oil is generally well tolerated. A small number of people report temporary digestive discomfort (mild nausea). Because it is rich in carotenoids, stools may take on an orange tint, but this is harmless. Consult a healthcare professional if you are taking anticoagulant medication. Use caution during pregnancy and breastfeeding (due to the presence of beta-carotene).
Does sea buckthorn oil help relieve dry mucous membranes?
Yes. Rich in essential fatty acids, particularly omega-7 (palmitoleic acid), sea buckthorn oil helps maintain moisture and flexibility in the mucous membranes (vulva and vagina, eyes, mouth). When taken orally, omega-7 nourishes membrane lipids, helps repair the mucosal barrier, and helps stabilize the tear film—useful for dry eyes. Daily intakes of around 270 to 360 mg of omega-7 are commonly recommended; La Rayonnante provides 360 mg per serving. The natural presence of vitamin E and carotenoids, along with the synergy with CoQ10 and lutein, enhance antioxidant action and daily comfort. In cases of severe or persistent discomfort, seek medical advice.
