Yes, you can roll with a 1.5 mm dermaroller around the eyes but read my answer (mine is #3) to this forum posting:
https://http://forums.owndoc.com/dermarolling-microneedling/Can-I-use-a-Dermaroller-on-this-area-under-the-eye The difference between the 1 mm and 1.5 mm dermaroller is that a 1.5 mm dermaroller reaches deeper into the dermis part of the skin (and it is more painful than a 1 mm). They both trigger collagen but if you have scars, a 1.5 mm is a more appropriate size.
You should avoid the sun as much as you can (wear a hat and sunscreen and do not suntan) for at least three days after dermarolling with long needled dermarollers. You can of course go outside, but protect yourself as much as you can.
After that, use a sunscreen and do not catch sun for some more days.
You can start with your treatments now, no problem. One week before your beach holiday, stop dermarolling.
Dermarolling is a relatively new method and you cannot find any long-term follow up studies.
Dermarolling is a safe method of skin rejuvenation because it doesn't remove any layers of skin, it doesn't use heat (heat can potentially cause hyperpigmentation, receding fat or necrosis), it doesn't thin the skin, it doesn't cause long term inflammation, it doesn't burn the skin, and since only fractions of skin are treated (each dermaorolling prick is surrounded by untreated skin) it heals extremely quickly.
Many of us accidentally pricked ourselves with a needle and there was never any side effect. Dermarolling is principally the same, only the needles are much thinner than a for ex. a sewing needle and you make very many pricks in one go.
You can use Emu oil.
Yes, I have been dermarolling for about three years and I have tried all products that we sell.
The most amazing result was on my décolleté where I rolled for quite severe sun damage and my skin looks really good there now.
Surprisingly, the deep wrinkles around my mouth improved more than the relatively shallow wrinkles around my eyes. I had to use a numbing cream when rolling around my lips.
I had no scars so I cannot report about that and I do have cellulite but I am past the age to bother about cellulite. I was also rolling and dry brushing my forearms for skin laxity and it also improved. Not to the point that it looks 15 years younger but it is a noticeable improvement.
I wanted to single-needle my husband's chicken pox scar but he said no way he will let me torture him with any needles :-)
