What patients mean when they say sensitive
Stinging under products that never used to sting. Tightness after washing. A grey, dull quality that sets in by the afternoon. Skin that reacts to a change in weather, to the shift from the Klang Valley heat into air-conditioning and back again, to something that has been in the routine for years without complaint. These are real experiences, and they are worth taking seriously.
But sensitive is a description of how skin is behaving, and behind that description there is almost always one of three things. A barrier that has stopped holding water and can no longer keep irritants out. A routine that has accumulated too many active ingredients and given the skin no time to recover. Or a skin condition with its own name: rosacea, eczema, a contact allergy to an ingredient used for so long that the connection has become invisible. Each of those three has its own diagnosis and its own treatment. The first two may lead here. The third one does not, and part of the consultation's job is knowing which road you are on.
What the skin barrier actually does, and how it breaks
The skin's outermost working layer has two jobs: keep water in, keep irritants out. It does this through a tight arrangement of cells and lipids that together form something closer to a functioning wall than a simple membrane. When it is working, skin holds moisture without much effort, stays comfortable under most products, and recovers from the day's exposures overnight.
When it is overdrawn, none of that holds. Water escapes faster than the skin can retain it. Irritants that a healthy barrier would deflect get through. Products that were fine before start to sting. The skin looks dull because dehydrated skin scatters light poorly.
The barrier gets overdrawn in recognisable ways. Active ingredients stacked on active ingredients with no recovery time between them. Retinoids, acids and exfoliants used together, or at concentrations the skin cannot yet tolerate. Sun exposure and heat accelerating water loss. The particular cycle of this climate, moving between outdoor heat and aggressive indoor cooling, repeated daily. The barrier does not fail dramatically. It thins gradually, and the symptoms start to look like sensitivity before they look like damage.
Why does this matter before anything else? Because anything layered onto a failed barrier either irritates or underperforms. A brightening treatment on skin that is already reactive will sting. A hydrating procedure on skin that cannot hold water will feel good briefly and deliver less than expected. Foundation first is not a philosophy. It is sequencing.
The honest answer: some barriers repair without any intervention
Before any protocol is discussed, this needs to be said plainly. Some barriers recover on their own, given time and a much simpler routine. What that actually looks like for a few months: a gentle cleanser, a plain moisturiser, sunscreen. Stop the acids. Stop the retinoid for now. Stop anything that stings. Keep what soothes. Nothing else.
The skin's own repair processes, given the space to run, will often do what a more involved plan was going to do. Comfort improves. Reactivity settles. Some of the texture and dullness resolves as hydration returns.
When that is the finding at consultation, that is the recommendation. It costs the clinic a booking. It is still the right call, and it is the one that gets made. The useful question is not what treatment to add. It is whether the skin needs anything added at all, or whether it needs things removed.
What ProNuLook is and what each component does
For skin where the barrier has stopped holding water and has not recovered on its own, ProNuLook is The Retreat Clinic's repair protocol. It is a considered combination of three components, each working at a different layer of the problem.
High-dose hyaluronic acid does the first job. Hyaluronic acid is a molecule the skin already makes, and its property is holding water, many times its own weight. In skin that has stopped retaining moisture, introducing it directly addresses the most immediate deficit. Comfort tends to improve first, and this is usually what patients notice in the weeks after a session.
Polynucleotides take on the repair side, the slower part. These are purified DNA fragments, in aesthetic practice typically derived from salmon, used here for their role in supporting the skin's own repair processes and the barrier itself. They have an established place in aesthetic practice. What they are not is a quick fix; their contribution builds across the months that follow, which is why judging at three months gives a more accurate picture than judging at three days.
A cocktail of biostimulators addresses the collagen layer. The goal is to prompt the skin's own collagen-producing activity rather than to substitute for it, so the structural improvement that emerges is the skin's own work, developing gradually. How biostimulation differs from other routes to collagen is worth understanding if this part of the protocol is new.
The mix, proportions and number of sessions are set by Dr Ong for the skin in front of him. ProNuLook is a protocol of this clinic, a combination rather than a single branded product, and it is adjusted for each patient rather than applied as a fixed formula.
What is done, how often, and what it will not do
ProNuLook is delivered by injection into the skin. Usually a single session, repeated about every three to four months to hold the effect. No fixed course is decided in advance; timing is set at consultation based on how the skin responds.
Two boundaries are worth understanding clearly. The first is the relationship with skinboosters. A skinbooster delivers hydration and skin quality improvement across an area; ProNuLook is a broader repair protocol aimed at skin whose barrier needs rebuilding rather than skin that needs a top-up. The two are related and sometimes used together in one plan. The second is the relationship with ReGlow. ProNuLook is the repair protocol, for depleted skin where the barrier is no longer holding water. ReGlow is the finishing protocol for skin that is already healthy. Some patients move from one to the other, and the assessment decides the order. A finishing treatment on a broken barrier wastes the work.
What ProNuLook is not the primary treatment for: laxity, lost volume, deep acne scarring, stubborn pigmentation. Each of those has its own diagnostic road, and texture, pores and scarring in particular warrant a different conversation. Some texture and pigment changes that ride on a weak barrier do improve as the barrier recovers, but that is a secondary observation, not a promise. ProNuLook is deferred in pregnancy and breastfeeding, waits out an active infection or a significant inflammatory flare at the area, and a known allergy to a component rules that component out.
The second complication: sensitive skin has become an identity
There is an entire product category built around the phrase, and it has made the useful question harder to ask. When sensitive skin is an identity, the response is to buy more things designed for sensitive skin. When it is a description of behaviour, the response is to find out what changed.
The consultation's first five minutes are often spent here: what you added in the months before this started, what you stopped, what the weather was doing, whether something you have used for years might now be the thing. That last one catches people off guard, because familiarity reads as safety. A contact allergy to an ingredient used daily for three years is not unusual. It is just invisible until it is not.
The surface is where skin shows its problems. Rarely where it has them. Find the cause, and then treat in the right order.
