ml vs. intensity in Harmy: what is the difference

People using Harmy for the first time often run into two controls that seem to say the same thing: the volume in ml and the Subtle, Moderate or Pronounced intensity. Understanding the difference avoids images that do not match what you had in mind and helps you steer the conversation with the patient.

What is ml in Harmy?

The ml is the volume you enter for each area in the Plan. The step is 0.5 ml, from 0.5 to 5 ml. For bilateral areas, such as Cheekbone and Temple, the value is the total and the AI splits it between the two sides. The more ml, the more noticeable the change tends to be.

What is intensity?

Intensity is a second control, set per area on the marking screen, with three levels: Subtle, Moderate and Pronounced. The default is Moderate. It adjusts how evident the change appears in the image, regardless of volume.

How do the two combine?

Think of a faucet and the size of the glass: the ml is the glass, the intensity is how far the faucet is open. A low ml with Pronounced intensity can show something more evident than you would expect; a high ml with Subtle tends to be more restrained. The marking shortcuts show typical combinations:

• First time: lips 1 ml Moderate; tear trough 1 ml Subtle.
• Maintenance: lips 0.5 ml Subtle; nasolabial fold 1 ml Subtle; malar 1 ml Subtle.
• Full harmonization: malar 2 ml, jaw 2 ml, chin 1.5 ml, lips 1 ml, nasolabial fold 1 ml (all Moderate); tear trough 1 ml Subtle.

Which one to adjust first?

If the projection came out exaggerated or timid, start with the ml in steps of 0.5. Intensity comes in as fine-tuning. This avoids switching levels without knowing what changed. For a weak projection, see projection too subtle and, for choosing a volume, choosing ml from 0.5 to 5.

How to explain it to the patient?

The conversation gets simple when you talk about "more" or "less" visible rather than numbers. Intensity is a way to show the patient a range of possibilities without committing the plan. See explaining Subtle, Moderate and Pronounced intensity.

Cautions

None of this replaces clinical assessment. Volume and intensity in the image are not a protocol, and the projection is always an illustrative simulation. For the full use of the plan, see marking areas and volumes.

An example to make it stick

A hypothetical example: a lip maintenance patient. You mark Lips at 0.5 ml with Subtle intensity, which is exactly the Maintenance shortcut. The image shows an almost imperceptible adjustment, consistent with the plan. Now imagine the same patient asks to see how far it could go. You keep 0.5 ml and switch to Pronounced: the image tends to look more evident even though the volume has not changed. Then you keep Subtle and raise it to 1 ml: the change also grows, but in a different way. Comparing the three images side by side shows the patient that there is a range of possibilities, and that the final decision depends on clinical assessment.

This kind of comparison helps move the conversation away from the number and toward what the patient sees. Just remember that each projection costs R$ 3.99, so it is worth choosing carefully how many variations to create. The most efficient is usually two: one discreet and one with more presence.

One last point: the ml appears in the quote by area, while intensity is only an image setting. If you change the intensity, the quote does not change because of it. See building a quote by ml.
