Frequently Asked Questions

How old do I have to be to have eyebrow microblading?

You must be at least 18 years or older.

Can I get a cosmetic tattoo if I am pregnant or nursing?

Eyebrow microblading or any form of cosmetic tattoo is prohibited for pregnant/nursing women.

What is cosmetic tattooing?

Cosmetic tattooing, also referred to as semi-permanent makeup or micropigmentation, it is the process of implanting all natural color pigments beneath the surface of the skin with tiny, sterile, disposable needles that produce the appearance of hair strokes to enhance the natural features of the face.

What is the difference between cosmetic tattooing and standard body tattooing?

Cosmetic tattooing is softer and more subtle – it is done delicately to create a more natural-looking result. Unlike body tattoos, cosmetic tattoos involve natural pigments. These pigments are designed to gently fade over time. Fading is desired as it allows the artist to make changes to color and shape over the years as client’s natural coloration and facial changes occur.

Does cosmetic tattooing hurt?

Dr. Castro will apply a topical anesthetic cream to numb the area, and then a local anesthetic will be superficially injected to ensure that the procedure will be as painless as possible.  Pain threshold levels vary from person to person. Having this service performed during your menstrual cycle may increase discomfort during your procedure.

How long does cosmetic tattooing last?

Cosmetic tattoo treatments are considered semi-permanent and will not wash off, however, they will fade over time and may need to be refreshed every 1-2 years. Frequency of touch-ups depends on a number of factors including: the pigment color used (lighter colors fade faster), sun exposure without SPF, excessive exfoliation to the area and if any chemical peels come into contact with treated areas will fade it faster. Please note that final results CAN NOT be guaranteed as each unique skin type will hold pigments differently and break down at different rates. You will be re-evaluated on how your skin has received the pigment at your touch-up appointment and any necessary changes will be made. Touch-ups are normal for cosmetic tattoo procedures, with each new procedure requiring at least 2 visits. The initial procedure followed by a free touch-up procedure, at least 2 months later. Previously tattooed areas will generally always require additional appointments.

How many treatments are needed?

For most clients, a minimum of two treatments are usually needed, at least 6-8 weeks apart. Everyone heals differently and at different rates. If you feel your cosmetic tattoo did not heal perfectly the first time, do not worry! The first treatment is just a foundation to build upon. You can go darker, add more density and perfect any areas that may have not retained pigment at your next appointment.

Microstroking Aftercare Instructions

It is essential that you follow these instructions after your microblading session:

Day One (Day of treatment): Keep the medical silicon band-aid on for 24 hours.

Day Two: After 24 hours, gently wash off the medical silicone with lukewarm water. Be extra careful not to tug or scrub the brows.

* After gently washing off the silicone, you can choose to apply post-care cream on your eyebrows several times a day. Apply the post-care cream with a cotton swab, and use no aggressive movement and/or manipulation of the skin. Make sure your hands are completely clean before caring for your eyebrows.

The following must be avoided during all nine days post-microblading procedure:


  • Increased sweating.
  • Practicing sports.
  • Swimming.
  • Hot sauna, hot bath, or Jacuzzi.
  • Sun tanning or salon tanning.
  • Any laser or chemical treatments or peelings, and/or any creams containing RetinA or Glycolic Acid on the face or neck.
  • Picking, peeling, or scratching of the micro pigmented area in order to avoid scarring of the area or removal of the pigment.
  • Performing tasks related to heavy household cleaning such as garage or basement cleaning where there is a lot of airborne debris.
  • Spicy foods.
  • Smoking.
  • Drinking alcohol in excess, as it may leas to slow healing of wounds.
  • Driving in open air vehicles such as convertibles, boats, bicycles, or motorcycles.
  • Touching of the eyebrow area except for when rinsing and applying the post-care cream with a cotton swab.  

Before showering apply a layer of post-care cream to protect your eyebrows from moisture. During the shower keep your face away from the showerhead. Itching and flaking may appear during the first seven days post-microblading procedure. However, experience has shown that by following these after-care instructions, these symptoms may quickly disappear. The healing of deeper wounds might last between 14-21 days. Touch-ups and/or correction of the shape-design is recommended only after this period. If you have any unexpected problems with the healing of the skin, please contact Dr. Castro immediately, to discuss further instructions at 914-732-3123. 

What to expect during and after your microstroking session

Your new temporary eyebrow will go through several phases during the healing cycle.

The pigment will appear very sharp and dark immediately after the procedure. This is because the pigment is still sitting on top of your skin, and has not yet settled in completely. The color of the pigment will soften gradually. Do not be alarmed if you see some pigment on the cotton swab, as this is excess pigment and/or body fluid that is naturally exiting your skin.

Once the healing of the skin starts taking place, it will look like dandruff flakes or dry skin. This might give you the impression that the color pigment is fading too quickly, however, this is just superficial color and dry skin being naturally removed from your eyebrows.

Once completely healed, always apply a layer of sunscreen SPF 30 up to SPF 50 on your eyebrows when exposed to the sun. Sun exposure might cause the color pigment to fade away more quickly. You can now enjoy your beautiful new temporary eyebrows. You will simply love your new gorgeous fresh look!
