HILO WAVE & Alltite: 2 reasons for a good combination (effects, timing) | Gangnam Seoul, Korea Dermatology Clinic Guide

Key summary: HILO WAVE and Alltite differ in how they work and what they are approved for, so combining them can be considered when sagging and hollowing appear on the same face. The effect of a combined treatment, however, comes not from adding two treatments together but from dividing areas and goals. If one treatment is enough for a face, there is no need for both, and combining them does not extend duration by a fixed amount.

More faces show sagging and hollowing together

These days, more people come to consultations with several overlapping concerns than with just one. The jawline has dropped, the front cheeks look empty, and skin firmness also seems to have declined. Ahead of an important appointment, many hesitate because lifting alone leaves the hollow cheeks and nasolabial folds, while volume treatment alone seems to leave the sagging.

That is why many ask whether HILO WAVE and Alltite can be done together. Because the two treatments differ in method and in the nature of the product, combining them can be considered depending on the condition of the face. Problems arise when treatment proceeds without separating which areas to address first and which areas should keep their existing volume.

Without that separation, changes in the facial contour and the existing hollowness can look out of step with each other. Injecting more than needed can also leave an impression different from what was expected. This article sets out, for those considering HILO WAVE and Alltite together, the difference between the two, how to divide areas and how to decide on timing.

First reason, Alltite and HILO WAVE work in different ways

Before discussing a combination, it helps to know that the two treatments are not of the same type. Alltite is a medical device approved as a shortwave stimulator using electromagnetic energy.

So when planning Alltite, hearing a full explanation of your current facial condition, the areas to be treated and the treatment method matters more than the device name. HILO WAVE goes in a different direction.

HILO WAVE is a tissue-repair biomaterial whose main ingredient is hyaluronic acid, and it is a medical device approved for temporarily improving facial wrinkles in adults. Alltite, which delivers energy, and HILO WAVE, which is injected, can hardly be seen as acting on the skin in the same way. This difference allows the two treatments to take on different roles, and that is the first reason to consider combining them.

Facial aging does not progress in only one direction. While the cheeks hollow, the lower face can lose firmness and sag, and some faces have hollowing under the cheekbones while the mouth area and jawline actually gain volume. For such faces, rather than setting a direction from a single concern, it is necessary to separate which factors are each having an effect.

So what I decide first in a combined plan is not the order, but which areas to treat for what purpose. Conversely, if one treatment is enough for a face, there is no reason to receive both. Depending on what is causing the hollow look and the sagging look, one of the treatments may not suit the current concern.

Second reason, the core of combining is dividing areas

What, then, needs the most care when actually combining them? It is not treating the whole face as one block in the same way. Picture a face whose jawline is blurring while the front cheeks and the area below the cheekbones are hollow; judging the lower face and the already empty front cheeks by the same standard would be unreasonable.

Likewise, HILO WAVE is not injected evenly along the line just because a nasolabial fold is visible. The approach differs depending on whether the fold looks deep because of the wrinkle itself or because of volume changes in the front cheek and surrounding area. This is why the range to be tightened with Alltite and the areas to receive HILO WAVE must each be checked separately against the current face.

When making a combined plan at O.N Clinic, I do not simply split the face into upper and lower zones. I look at volume below the cheekbones, how full the front cheeks are, where the nasolabial fold begins and how the lower face and jawline flow, and then decide separately where to use Alltite and where to use HILO WAVE. It may sound simple, but on an actual face the boundary between sagging areas and empty areas is not sharply drawn.

Especially in faces with little fat or prominent cheekbones, shifting the lifting area only slightly can make existing hollows more noticeable. Conversely, adding volume to a mid-face that already has plenty can make the face look wider and heavier. There is no reason to use HILO WAVE where Alltite alone is enough, and if the concerns differ, a suitable treatment can be considered for each.

Timing is set by looking at the schedule and the range together

A combined treatment does not aim to do a lot of both on the same day over the same range. I first check whether the right method can be used for each area, and then set the timing. If you have an important date, whether it is possible depends on the time left and the treatment range.

Alltite is considered when a quick tightening feel is needed, and HILO WAVE when you want to fill hollow areas while also caring for skin condition. Reactions after treatment also differ; redness, warmth and tenderness may temporarily follow Alltite, while swelling, bruising and tenderness may temporarily follow injection treatments such as HILO WAVE, and their degree varies by person. With an event ahead, it is better to set the timing with the period for these reactions to settle included.

What to check in a consultation before combining

If you are considering HILO WAVE and Alltite together, I hope you will go a step beyond asking whether getting both is better. A more useful standard is hearing a separate explanation of which part of your face each treatment covers and why. I recommend separating sagging from volume loss first, and then judging whether a combination is needed or whether one treatment is enough.

A combination does not promise everyone a bigger change or longer-lasting results. For both energy-based lifting and injection treatments, the suitable method depends on skin thickness, fat distribution, facial structure and the degree of sagging.

Frequently Asked Questions

I have an appointment coming up. Can I get both treatments at once?

The answer depends on the days left and the range to be treated. Alltite can be considered when quick tightening is needed, and HILO WAVE when volume support and skin condition care are needed, and the time for post-treatment reactions to settle should be included in the plan.

If I have little facial fat, could I look more hollow after lifting?

Using strong energy on an area that already lacks volume can make hollowing relatively more visible. If you have little facial fat, it is important to separate the range for lifting from the areas where volume will be filled.

If my nasolabial folds are deep, should HILO WAVE go only there?

It is hard to decide from the position of the line alone. Some faces have deeper folds because the front cheek has descended, so the injection site is chosen while looking at the surrounding volume as well.

Does combining the two treatments make results last longer?

It is hard to say that duration grows simply because two treatments were received. The meaning of combining lies in addressing different causes of aging separately, and how long results last varies with skin condition and treatment range.
