Short answer: for perimenopausal skin, an oil cleanser is usually the right call. Foaming cleansers strip roughly 8% of your skin's free fatty acids in a single wash, and after 40 your barrier no longer rebuilds that overnight. Oil cleansing dissolves the day off the surface without reaching into the structural lipids underneath.
The most common question we hear is not which cleanser to buy. It is why one type feels fine and another leaves skin feeling like it has been scraped. The answer is that most people have never been told what their cleanser is actually doing at a chemistry level. Once you understand that, a lot of things click into place.
Here is a walk through the five main categories of facial cleansers, what each one is doing to your skin, and exactly why the Rinse No. 1 Oil Cleanser was formulated the way it was.
The Five Types of Cleansers (and What They Actually Do)
Foaming cleansers are probably what you grew up using, and they have been the default in American skincare since the mid-twentieth century. They rely on surfactants, molecules that have a water-loving head and an oil-loving tail. When you lather up, those surfactant molecules form tiny clusters called micelles that grab onto oil and dirt and carry them away with the rinse. Foaming cleansers are best for oily and combination skin types that produce enough sebum to tolerate the lipid loss. They are effective at removing heavy makeup and sunscreen. The problem is that they are not selective. Surfactants pull out your skin's own fatty acids along with the dirt. Research published in the International Journal of Cosmetic Science found that surfactant cleansing removed roughly 8% of the free fatty acids in the stratum corneum after a single wash. At 25, your skin rebuilds that overnight. At 47, in perimenopause, your skin may not fully recover before the next wash. If your skin feels tight or dry within an hour of washing, your foaming cleanser is very likely the reason.
Micellar water originated in France, where the hard mineral content in Parisian tap water made rinsing with water itself irritating. The solution was a no-rinse cleanser: tiny micelle clusters pre-formed and suspended in soft water, designed to lift makeup and debris with a cotton pad. It is best for light makeup days, travel, or as a quick morning refresh. It works well for sensitive skin that reacts to heavy rubbing or rinsing. The limitation is that most micellar waters still contain mild surfactants, and they are designed to be wiped off rather than rinsed. That wiping creates friction, and for skin that is already sensitized from hormonal shifts, friction adds up. Micellar water is also not ideal for removing heavy sunscreen, waterproof makeup, or a full day of oil-based environmental residue. If you are wearing SPF 30 or higher daily (which you should be), micellar water alone is probably not getting all of it off.
Cream cleansers are emulsions that combine a water phase with an oil phase, and they have been a staple of European skincare for decades. They cleanse without stripping as aggressively as foaming products and leave a slight film that can feel moisturizing. They are best for dry to normal skin types and for people who want a gentle daily wash that does not disrupt the moisture barrier. The limitation is that cream cleansers are not always effective at removing heavier residue like mineral sunscreen or long-wear foundation. The preservative systems in water-containing products also tend to be more complex, which matters if your skin reacts to common preservatives. For perimenopause skin that is both dry and reactive, a cream cleanser can be a decent option, but it may not be doing the full job at the end of a long day.
Cleansing balms became popular in the K-beauty wave of the 2010s, though the concept of using solid fats to clean skin goes back centuries. They are solid at room temperature and melt when you massage them in, dissolving oil-based debris through direct lipid contact. The format is convenient and travel-friendly. Balms are best for dry skin types and for people who enjoy a more tactile, massage-oriented cleansing ritual. The concern with many balm formulations is the emulsifying wax system. Some balms use heavy emulsifiers like PEG compounds that can leave a waxy residue on the skin, and that residue can interfere with the absorption of whatever you apply next. The other issue is that balms require warm hands and some patience to melt and spread, which makes them less practical for a quick evening wash.
Oil cleansers are the simplest concept in the group, and the oldest. Oil cleansing dates back to ancient Rome and Greece, where olive oil was used to dissolve dirt and was then scraped off with a strigil. The modern version works on the same principle: like dissolves like. You apply oil to dry skin, massage it in, and the cleanser oils dissolve the oil-soluble debris sitting on your face. Sebum, sunscreen, makeup pigments, environmental grime. When you add water, a light emulsifier turns the whole thing milky so it rinses clean. Oil cleansers are best for dry, mature, and barrier-compromised skin, though well-formulated versions work across all skin types. No aggressive surfactants reaching into your barrier. No friction from wiping. Just solubility chemistry doing what it was always going to do. The problem with a lot of oil cleansers on the market is poor formulation: comedogenic oils like unrefined coconut oil, no emulsifier system (so the oil does not rinse and leaves residue), or added fragrance that irritates sensitized skin. A badly formulated oil cleanser will break you out. A well-formulated one will not.
That last category is the foundation of the Rinse No. 1 Oil Cleanser, and there is a specific reason why.
Why Oil Cleansing Makes Chemical Sense for Hormonal Skin
A 2022 study in Scientific Reports looked at what menopause actually does to the stratum corneum's ceramide profile. The findings were specific: post-menopausal skin contained significantly lower levels of ceramides with shorter average chain lengths compared to pre-menopausal skin. Estrogen directly affects ceramide synthesis. When it drops, so does your barrier's ability to hold itself together.
When your ceramide and lipid levels are already depleted, the last thing you want is a cleanser that pulls even more lipids out of the matrix. Surfactant-based cleansers do exactly that. Even mild ones cause measurable increases in transepidermal water loss after a single wash. Over weeks and months, that adds up.
An oil cleanser works on the surface. It dissolves what is sitting on top of your skin without reaching into the structural lipids deeper in the barrier. For skin that is already running on a thinner lipid budget, that distinction is not a marketing angle. It is just chemistry.
Why These Specific Ingredients
Every oil in the Rinse No. 1 Oil Cleanser is there for a specific reason. Here is the formulation logic behind each one.
Fractionated coconut oil (MCT) is the workhorse at 45% of the formula. MCT stands for medium-chain triglycerides. These are shorter fatty acid chains, primarily caprylic (C8) and capric (C10) acid, which means they absorb quickly and do not sit heavy on the skin. They are also non-comedogenic. Full coconut oil is notoriously pore-clogging for a lot of people. Fractionated coconut oil is a completely different ingredient. The long-chain fatty acids (the problematic ones) have been removed, leaving behind a lightweight oil that dissolves debris efficiently and rinses clean.
Jojoba oil at 30% was chosen for its molecular structure. Jojoba is technically a liquid wax, not an oil, and its wax ester profile is remarkably similar to human sebum. A 2024 study in Frontiers in Pharmacology found that jojoba decreased transepidermal water loss within 24 hours and reinforced the hydrolipid barrier after 14 and 28 days of use. It even reduced sebum secretion by 23% over 28 days, which suggests it helps regulate oil production rather than just adding to it. For skin that swings between dry and congested during hormonal shifts, that is a meaningful property.
Olive-derived squalane at 15% mirrors squalene, a lipid your skin produces naturally but produces less of as you age. Squalane is the hydrogenated, shelf-stable version. It is lightweight, fully saturated (so it does not oxidize easily), and integrates into your barrier rather than sitting on top. Research has also shown it counteracts UVA-induced oxidative stress and reduces inflammatory markers like NF-kB and COX-2 in dermal fibroblasts. It is not just a slip agent. It is functional.
Calendula-infused sunflower oil at 8% provides the anti-inflammatory backbone. A systematic review in Wound Repair and Regeneration evaluated 14 studies on calendula and found consistent evidence for faster resolution of inflammation and increased tissue repair. The active compounds, carotenoids, triterpene alcohols, and flavonoids, work together to calm reactive skin. Infusing these into sunflower oil (which is rich in linoleic acid, another barrier-supportive fatty acid) creates a delivery system that makes chemical sense.
Vitamin E and rosemary antioxidant extract at 0.5% each are the stability team. They protect the oils in the formula from oxidizing, which means the bottle in your bathroom stays effective from the first pump to the last one.
How It Fits Into the Lineup
If you are using Blue Hour Tallow Balm at night, the Rinse No. 1 Oil Cleanser is the first step. Cleanse on dry skin, add water to emulsify, rinse, apply balm to damp skin. Two products. Under two minutes. Your barrier gets cleaned without getting punished, and then it gets fed.
For mornings, you may not even need to cleanse at all. If your skin feels balanced when you wake up, a splash of water and your morning moisturizer is plenty. Rinse No. 1 is for end-of-day removal: sunscreen, makeup, the day's accumulated residue. Let it do that one job well.
This formula was built out of necessity. Perimenopause skin that was reactive, a gel cleanser that was quietly making things worse, and a need for something that dissolved the day without dissolving the barrier along with it. Every ingredient has a job. Nothing is in there for filler or fragrance or label appeal.

Questions people ask
What type of cleanser is best for perimenopausal skin?
An oil cleanser, in most cases. Falling estrogen reduces the ceramides and fatty acids that hold your barrier together, and surfactant-based foaming cleansers remove more of those lipids with every wash. An oil cleanser dissolves surface debris without reaching into the structural lipids underneath.
Does oil cleansing clog pores?
Not when the formula is built correctly. Breakouts from oil cleansing usually trace back to comedogenic oils like unrefined coconut oil, or to a missing emulsifier so the oil never fully rinses. A well-formulated oil cleanser using fractionated coconut oil, jojoba, and squalane rinses clean and does not congest skin.
Is fractionated coconut oil the same as coconut oil?
No. Fractionated coconut oil has had the long-chain fatty acids removed, leaving mainly caprylic and capric acid. Those are lightweight and non-comedogenic. Full coconut oil is pore-clogging for many people. They behave like two different ingredients.
Will an oil cleanser remove sunscreen and makeup?
Yes, and better than micellar water. Sunscreen and most makeup are oil-soluble, so like dissolves like. Apply to dry skin, massage, then add water to emulsify and rinse.
Do I need to cleanse in the morning?
Often not. If your skin feels balanced when you wake up, water and your moisturizer are enough. Oil cleansing is for end-of-day removal of sunscreen, makeup, and accumulated residue.
Does a cleanser really strip the skin barrier?
Measurably, yes. Research in the International Journal of Cosmetic Science found surfactant cleansing removed roughly 8% of the free fatty acids in the stratum corneum after a single wash. Younger skin replaces that overnight. Perimenopausal skin often does not before the next wash.
