Research shows that demodex (a face mite) has been associated with various skin issues of the face such as acne, rosacea, blackheads and so on. These mites live in pores and hair follicles typically on the scalp, cheeks, nose, eyebrows and sometimes in the roots of eyelashes. The worm-like mite varies in size from .1mm to .4mm, has tiny claws and scales over its entire body that allow it to anchor itself in the hair follicle. Female mites may lay up to 25 eggs in a single hair follicle. These mites grow and become tightly packed causing the inflamed irritation. Mature mites emerge from the hair follicle at night to mate and lay more eggs into hair follicles where the newly hatched larvae will feed on sebaceous oil.

In Robert Tisserand's Skin Care Series, he notes that rosacea may be associated with:
- Spider veins of papules and pustules
- Exacerbated by demodex mites
- Associtated with gastric Helicobacter pylori

Dr. Neil Bhatia conducted a double-blind placebo-driven study on a select group of 42 patients with the diagnoses of Rosacea, Photodamage/Actinic Dermatitis, Acne, Seborrheic Dermatiti and Perioral Dermatitis and concluded that Seabuckthorn berry had a positive effect on eliminating this mite issue. (I have not found the medical abstract supporting this information.)

Testimonies
1. I researched causes of Rosacea and found an MD who has studied this for years in San Francisco. He says the same mite that causes acne causes rosacea, so I tried Purify applied neat (undiluted), and after one month I have no outbreaks.
[HEO's Comments: While using Purify undiluted did not cause her any harm, we strongly suggest diluting the oils to avoid skin irritation or sensitization issues.]

2. I was diagnosed with rosacea several years ago and was told that there was no cure. I was told that the treatment to keep it under control involved daily application of a topical antibiotic. This did not seem like a good long-term solution to me. I had read that the condition may be caused by a bacteria and researched oils that were highly antibacterial and were good for the skin. I settled on Ylang Ylang and Cypress, applying the oils at first twice a day (a couple of drops of one in the AM and couple of drops of the other in the PM). The oils were effective for me and you cannot tell that I ever had the condition. I still occasionally use the oils for maintenance because they are healthy for my skin. In addition to the oils, a healthy diet was key.

3. I found that Seabuckthorn Berry oil and Neem oil mixed with Jojoba eased my rosacea. I use this nightly after washing my face with goat's milk soap. In less than a week, I can see a dramatic difference. My dermatologist told me that rosacea is an overgrowth of the human demodex mite.

4. From Karen  (the creator of this blend): I've only been using Rosacea Recover for a few days, and the difference it has made in my rosacea is amazing. The arrival of the Lavender Hydrosol and oils couldn't have been timed more perfect; I was in the middle of a terrible breakout. This blend has stopped the redness and itching as well as the awful looking bumps. I've been using the blend three times per day and will do so for a week, and then I will taper it off to two times per day for another week and then once per day. I'm going to stick with one time each day for a week and see how it goes, and then probably taper off some more. I've also been using the Lavender Hydrosol as I've needed in between application, usually when I start to feel an itching or burning sensation on my facial skin. The combination of the Rosacea Recover blend and your Lavender Hydrosol have so far worked a miracle for me. I'll keep you posted. You have no idea how thrilled I am to have finally put together something that is actually working and working well. The difference in my face, in just 3 days, is remarkable. - Karen

1 Month UPDATE: The Rosa-Recover is working fabulously for me. It has really brought my rosacea under control. I can't believe the difference it's making. I've even noticed a difference in the spider veins that showed up on the sides of my face... they are much less noticeable... YAAYYY!!! You really have no idea how grateful I am to have found you and your website. I was spending a great deal of money per month trying to get this rosacea under control. I found a Chinese herbalist and was taking her pills. They did work for me, but I just couldn't afford that expense every month, and I was having to take 16 pills per day... UGH! This blend is MUCH more affordable, and not having to swallow a fist full of pills twice a day is great. B I G H U G S - Karen
2 Month UPDATE: I'm having great success with the Rosa-Recover blend. I made a batch and added Seabuckthorn. In all honesty, I think I like the blend without the Seabuckthorn better. It has a nicer smell and a smoother texture. I can't say with any certainty that adding the Seabuckthorn made any difference. Both blends worked equally well for me. The blend, as is has helped my rosacea spider veins a great deal; however, they're still noticeable, so I'll try another blend for that. I can't tell you how happy I am to have found you and HEO. This blend has definitely worked better than anything else I've tried, and believe me, I've tried quite a few things. I'm using the blend 1 time per day now and it still seems to be doing great. I've found that I can eat pretty much anything I want and still keep the rosacea under control. I've developed a sensitivity to peanut butter and chocolate combination. When I eat it I break out. When this happened, I went back to using the Rosa-Recover 3 times per day and then worked my way back to 1 time. I haven't had the horrible looking break outs I was experiencing prior to using this blend. Yaaayyyy!
1 1/2 Year UPDATE:
Just wanted to give you an update on my rosacea issue and using Rosa-Recover. My rosacea has been kept under great control, and I have experienced an unexpected but pleasant side-effect. The Rosa-Recover also removed a mole from my neck and some small skin tags. I just started dabbing the Rosa-Recover on my mole and skin tags three times a day, figuring, what could it hurt? One day, they just peeled off. No pain, no fuss and no return for about a year now. Thank you again for putting this blend together for me. It really has been a great product for me.

The following is offered by Karen who formulated Rosa-Recover:
Week 1
Use 1-2 drops of Rosa-Recover on the forehead and cheeks, 3 times per day. 
Gently spread the oil to cover your forehead and each cheek. It will absorb into the skin. 
Do not rub in. The rubbing will irritate your rash.
Spray your face with Lavender Hydrosol 20-30 minutes after each oil use.
Use the Lavender Hydrosol as you feel necessary in between your oil applications. 

Week 2
Same as above, reducing theRosa-Recover application to 2 times per day.
If your break out does not continue to lessen or worsens, go back to using the Rosa-Recover 3 times per day for another week, then try to reduce the use to 2 times per day. 

Week 3
Same as above, reducing the Rosa-Recover application to 1 time per day.
If your break out does not continue to lessen or worsens, go back to using the Rosa-Recover 2 times per day for another week, then try to reduce the use to 1 time per day.

2.  I have tried the sample of the blend, and just as I thought, it made my rosacea much worse. There are two different kinds of rosacea. One caused by bacteria and one caused by autoimmune disorders. Mine is caused from AI. Must be the lady that had such great success, has the bacterial rosacea. - Deb 

3. I have to send a message of thanks, and of testimony. For the past two months I have been struggling through a very difficult period of suddenly severe rosacea. I was at the point where I really did not want to see other people because of how terrible my skin looked. Last night I read the revelatory explanation you have on rosacea and started to understand what exactly I am battling. I had a bottle of Rosa-Recover in my cabinet that I purchased months ago when I had very faint signs of the disease diagnosed. (I hadn't tried it during this round because doctors weren't sure that it actually was Rosacea until days ago.) Anyway, I applied Rosa-Recover before bed, and when I woke in the morning I was praising God and rejoicing at how dramatically better my skin looked. I will continue to treat with this blend according to the suggestions on the HEO website. I am just so thankful for the work you do and thankful that you offer a well-researched alternative to conventional pharmaceuticals, which so often fail to address the root of the ailment. Thank you. - Courtney

4. I had a Rosacea flare-up on Easter. It was truly awful - deep purple burning and itching. In the past, this would be the beginning of a multi-week process of trying to get my skin to calm down. I used Rosa Recover three (3!!) times, and my skin is back to normal! I applied it with damp hands straight from the bottle at night, and then again the next morning and mid-day that same day. (I didn’t even think to put it on last night because it was so much better.) Thank you so much for this blend! - April

5. I can't believe what clean eating and using Seabuckthorn Berry with Hopewell's Uncented Cream did for my rosacea! I'm thrilled! Clean eating for 6 weeks helped the bumps to disappear, and the Seabuckthorn Berry/Cream calmed the redness in just a week. I apply 2-3 drops of Seabuckthorn Berry EO, and then I apply the unscented cream over that. Warning: It goes on orange. Eating clean for me means no sugar, bread or rice. I try to keep my carbs low but will still indulge in a little baked potato or starchy veggies every now and then. No processed foods. I DO eat quite a bit of dairy though. - Kristi

Essential oils noted for Rosacea
Cistus or Rock Rose essential oil not only smells wonderful but is also offers therapeutic care for mature skin and works well blended with other oils for Rosacea.

German Chamomile essential oil is beneficial for Rosacea because it soothes and calms the skin, aids tissue regeneration and heals. It is used in aromatherapy as an analgesic, anti-inflammatory, antiallergenic and fungicidal.

Helichrysum essential oil is antibacterial, anti-fungal, anti-viral and known for fading bruises over night. It is excellent for skin rashes, irritations and Rosacea, especially when blended with German Chamomile.

Lavender essential oil is widely used. It is anti-viral, anti-fungal and anti-bacterial. High altitude French lavender is most often used in blends for acne and Rosacea.

Neem Seed essential oil is known to help manage acne and soothe the skin.

Neroil has a sebum balancing effect to balance oily and dry skin and is often blended with other essential oils to cure Rosacea. I find the aroma very pleasant.

Rosewood essential oil is noted for increasing elasticity and soothing the skin, so is an ideal addition to a blend if you have mature skin as well as Rosacea. See Corriander as an alternative to Rosewood.

Seabuckthorn Berry essential oil is beneficial to the skin for numerous issues including rosacea because it is anti-inflammatory and helps support cellular regeneration.

Jojoba wax (oil) is an excellent choice for a carrier.
