Home / IPL, SHR and OPT explained for buyers

The explanations below are general descriptions of technology classes. They are not claims about any unit from this company, and they are not a substitute for a unit specification. The company's own website lists IPL, SHR, and OPT as families at family level only, with no model and no figure attached to any of them. The one unit on this site that touches these terms — the vertical SHR IPL unit — is described on its own detail page, with its figures labelled as shop listing figures.

IPL: pulsed light in pulses

IPL stands for intense pulsed light. In general terms, an IPL unit delivers broad-spectrum light in pulses applied to an area. The operator places a handpiece, delivers a pulse or a short series of pulses, and moves to the next area. That stationary, pulse-by-pulse method is the classic IPL description, and it is how most buyers first picture light-based hair removal.

IPL is a class, not a unit. Within the class, units differ in the light range they use, the pulse patterns they offer, the cooling they provide, and the handpieces they include. A buyer who asks about an IPL machine should ask which of those the unit on the order provides, and ask for the answers in writing — because two units both called IPL machines can differ on every one of them.

IPL is also used beyond hair removal. Listings describe IPL modes for skin treatment, including modes named for skin rejuvenation and pigment work. Those are listing descriptions for specific units, not properties of the IPL class as a whole. A buyer should ask, for the unit on an order, which modes it provides, rather than assuming that every IPL unit provides every mode.

The IPL family on this site is covered at family level, and the SHR IPL vertical unit is the one IPL-related unit described in detail. Its listing describes IPL working modes alongside an SHR sliding technique — an example of how a single unit can carry two of the three terms at once.

SHR: the sliding method

SHR stands for super hair removal. In general terms, SHR describes a sliding, in-motion method: the handpiece moves continuously over an area while delivering light at a lower energy per pass, repeated over several passes, rather than delivering single high-energy pulses to stationary spots. That sliding description is the core of the SHR term, and it is how the shop listing for the SHR IPL unit describes the technique.

The sliding description changes the questions a buyer should ask. Instead of asking only about pulse energy, a buyer should ask about the sliding method itself: how the handpiece movement is described for the unit, what cooling accompanies it, and what handpieces are included. The answers should come from the current product page for the unit on the order, in writing.

SHR is also a class, not a unit, and suppliers use the term with different degrees of precision. Some use it for any unit with a sliding mode; some use it as a family name for a range of units. A buyer should ask the supplier to confirm, for the unit on an order, whether SHR describes its working method, its family name, or both — and ask for the answer in writing.

The SHR guide on this site covers the concept in general terms, and the SHR category page covers the family at family level. Neither presents an SHR model, because no standalone SHR model is evidenced in detail beyond the SHR IPL unit, which has its own detail page.

OPT: controlled pulse output

OPT stands for optimal pulse technology. In general terms, OPT describes a pulsed-light mode in which the pulse output is controlled to stay even across the pulse, rather than rising and falling sharply. That controlled-output description is the core of the OPT term, and it is a general description of the class, not a claim about a specific unit.

The controlled-output description changes the questions a buyer should ask in a different direction from SHR. Instead of asking about movement, a buyer should ask about pulse control: how the unit describes its pulse output, which pulse modes it provides, and what settings the operator can adjust. The answers should come from the current product page for the unit on the order, in writing.

OPT is also a class, not a unit, and it appears in catalogues both as a standalone family and as a mode inside IPL or SHR units. A buyer should ask the supplier to confirm, for the unit on an order, whether OPT describes its working method, one of its modes, or its family name — and ask for the answer in writing.

The OPT category page on this site covers the family at family level, with no model published, because no OPT model is evidenced in detail in the material used for this site. The OPT, SHR and IPL comparison guide puts the three terms side by side for buyers who are comparing them.

How the three terms overlap

The three terms overlap because they describe different aspects of the same equipment. IPL describes a light source and a pulse method. SHR describes a delivery method — sliding rather than stationary. OPT describes a pulse-control method — even output rather than peaked output. A single unit can therefore be described with two terms at once, as the SHR IPL unit is: IPL for its light modes, SHR for its sliding technique.

That overlap is why a buyer should never choose a unit from its term alone. Two units both called SHR machines can differ in light source, pulse control, cooling, and handpieces. Two units both called IPL machines can differ in whether they offer a sliding mode. The term tells a buyer which questions to ask; it does not answer them.

A practical way to compare units across the three terms is to ask the same four questions of each unit, and to record the answers in writing: which working method does the unit use, which modes does it provide, which handpieces and cooling parts are included, and which specification figures come from the current product page. Units that answer those four questions clearly can be compared; units that cannot should be treated as unconfirmed until they can.

What this post does not do

This post does not recommend one approach over the others. A general comparison cannot settle which unit suits a given salon, because suitability depends on the unit's specification, its included parts, its support terms, and the salon's own needs — none of which a general description can supply.

This post does not state a wavelength, a power figure, or an energy figure for any approach, because no such figure is evidenced for a company model in the material used for this site. Any figure a buyer needs should come from the supplier for the unit on the order, from the current product page, in writing.

This post does not present any unit from this company as an IPL, SHR, or OPT model, beyond the SHR IPL unit already described on its detail page with labelled shop listing figures. For every other unit, the correct next step is a question to the supplier, not a conclusion from a description.
