There is a persistent idea in skincare — particularly among people with oily or combination skin — that the goal is to get skin as clean as possible. To remove oil, tighten pores, and leave the face feeling squeaky clean after cleansing.
This idea is wrong. And acting on it causes more skin problems than almost any other single habit.
Stripping your skin's natural oils does not give you better skin. It gives you a compromised skin barrier, increased oil production, heightened sensitivity, and accelerated ageing. Here is why — and what to do instead.
What your skin's natural oils actually do
The skin produces sebum — a complex mixture of lipids, fatty acids, and wax esters — through the sebaceous glands. Sebum is not a problem to be solved. It is a functional substance that performs several critical jobs.
It forms part of the skin's acid mantle — a slightly acidic film on the surface that acts as a first line of defence against bacteria, fungi, and environmental pollutants. It lubricates the skin and hair follicles. It contributes to the moisture barrier, slowing transepidermal water loss and keeping the skin hydrated from within.
Sebum also contains squalene — the natural precursor to squalane — which has antioxidant properties and helps protect the skin from oxidative damage. In other words, your skin is already producing one of the most valued ingredients in natural skincare. Stripping it away is counterproductive in the most literal sense.
What happens when you strip it
When the skin's natural oils are removed by harsh cleansers, astringent toners, alcohol-based products, or over-exfoliation, the consequences are immediate and cumulative.
The moisture barrier is compromised. Without its lipid layer, the skin loses water rapidly — a process called transepidermal water loss — leading to dehydration, tightness, and a dull, stressed appearance. The skin becomes more reactive to products and environmental triggers that it would previously have tolerated without issue.
The skin also responds to the removal of oil by producing more of it. Sebaceous glands increase output when the surface is stripped — which is why many people with oily skin find that the more aggressively they cleanse, the oilier they become. The skin is not misbehaving. It is compensating rationally for the loss of something it needs.
Over time, repeated stripping accelerates the breakdown of the skin's structural proteins. Collagen and elastin are more vulnerable when the barrier is compromised. The chronic low-level inflammation that results from a damaged barrier — sometimes described as barrier stress — contributes directly to the processes associated with premature skin ageing.
The cleanser problem
The primary culprit in most people's routines is their cleanser. Conventional foaming cleansers — including many marketed as gentle or suitable for sensitive skin — rely on sulphates and other surfactants that are highly effective at removing oil. Too effective, in many cases.
Sodium lauryl sulphate and its derivatives are among the most studied skin irritants in cosmetic chemistry. They disrupt the lipid structure of the skin barrier, increase permeability, and have been shown to cause measurable changes in barrier function even after a single use. They are widely used because they create a lather that consumers associate with cleanliness — not because they are good for skin.
A good cleanser removes the things that should be removed — environmental pollutants, make-up, the day's accumulation of particulate matter — without removing the skin's own lipids. This requires a different kind of formulation entirely: one built around oils and gentle emulsifiers rather than sulphates and foaming agents.
What gentle cleansing actually looks like
Oil-based and balm cleansers work on the principle that like dissolves like — oil removes oil-based impurities without disrupting the skin's own lipid layer. Micellar water, when properly formulated, can remove surface impurities without stripping. Low-lather, sulphate-free cleansers built around skin-compatible surfactants are significantly less disruptive than their foaming counterparts.
The sensation of squeaky-clean skin after cleansing is not a sign that a cleanser has worked well. It is a sign that the skin's natural oils have been removed. Well-cleansed skin should feel comfortable, balanced, and slightly hydrated — not tight, not dry, not taut.
The Pūraka Cleansing Wash is built around this principle. Formulated with sweet almond oil and castor oil, it removes impurities effectively without stripping the skin's lipid layer. The essential oils of sweet basil, lemon, and bergamot contribute antibacterial and brightening properties without the need for harsh surfactants. It cleanses without compromising — which is the only standard worth having.
Rethinking the oily skin routine
For people with oily skin, the instinct to strip is particularly strong — and particularly counterproductive. Oily skin is not a problem skin type. It is skin that produces more sebum than average, which can be managed without stripping.
The correct approach is not to remove all oil aggressively and then deal with the rebound. It is to cleanse gently, support the barrier, and allow the skin's own regulatory processes to function without interference. Skin that is not in a constant cycle of stripping and overproducing will, over time, produce less excess oil — not more.
This can take a period of adjustment. Skin that has been stripped regularly takes time to recalibrate. The transition period, during which the skin may produce more oil before it stabilises, puts many people off. Persisting through it is worth it.
The underlying principle
Skin is not an adversary to be defeated. It is a complex, self-regulating organ that does an extraordinary job of protecting the body — when it is supported rather than undermined.
The skincare industry has done considerable damage by promoting the idea of aggressive cleansing as a virtue. Squeaky clean is a marketing concept, not a skin health goal. The skin's natural oils are not a problem. They are the starting point for everything that keeps skin healthy, resilient, and protected.
Work with them, not against them.
