Why more steps often means worse skin
168 dermatologists were asked. The answer was close to unanimous.
In a survey published this year in Clinical, Cosmetic and Investigational Dermatology, researchers put a simple question to dermatologists and dermatology residents: what do you make of the multi-step routine?
168 responded, 146 of them board-certified. 91.6% said they were concerned about it. And 88.1% said they regularly treat skin problems caused by skincare itself. Not by neglect. By use.
What actually walks into the clinic
The conditions they reported, in order of how often they see them:
- Irritant eczema, 69.6%
- Perioral dermatitis, 53.0%
- Allergic contact dermatitis, 52.4%
- Acne exogenica, 42.3%
These are not exotic reactions. They are the everyday consequence of asking too much of one face.
When asked which ingredients came up most, fragrance led at 53.0% and retinoids followed at 41.7%. And there was one specific pairing in the data worth sitting with: alpha and beta hydroxy acids were significantly associated with perioral dermatitis, the rash that shows up around the mouth and nose and that most women assume is hormonal.
The most telling number is the smallest one. Only 12.5% of them actively recommend a multi-step routine. Nearly all of them recommend daily sunscreen.
The word "sensitive" is doing a lot of hiding
Roughly 45% of women describe their skin as sensitive, according to a systematic review and meta-analysis. The reviewers are careful to say that questionnaire studies likely over-estimate it, and we will be careful too. Even discounted, it is an enormous number of women who believe their skin is constitutionally difficult.
Some of it is. Much of it is a barrier that has been worked too hard and has stopped absorbing the abuse quietly.
The distinction matters because the two situations call for opposite responses. Genuinely reactive skin needs careful ingredient selection. An over-worked barrier needs subtraction, and it will get better on its own if you let it.
The part we would rather not write
That survey named acids. PHYTX 03 · Power Trip Serum is an acid.
If your skin is reactive right now, it is not your bottle. Not this month, and possibly not at all. Lactic acid is in fact the standard agent laboratories use to provoke stinging when they want to test for sensitive skin, which tells you something about what an acid asks of a compromised barrier.
We would rather say that than sell you something that stings. It is the least profitable paragraph we will publish this year.
What to do instead, in order
One: take something out. Not everything. One thing, starting with whatever is strongest or newest. Fragrance and retinoids are where the survey points first.
Two: give it fourteen days before you judge it. Barrier recovery is not visible on a daily timescale, and the temptation to add something back on day four is the mechanism by which most people stay stuck.
Three: keep the two steps that only ever help. Water at the surface, then something to hold it there. That is a humectant followed by a moisturizer, and it is the pairing dermatology treats as the standard of care for dry and compromised skin. The American Academy of Dermatology recommends routine moisturization specifically to maintain barrier integrity.
Four: sunscreen. It was the one thing nearly every dermatologist in that survey agreed on.
Where we sit in this
We make five formulas and we do not think you need all five every night. For reactive skin the version of our routine that makes sense is two of them: PHYTX 02 · Hit or Mist Toner for the water step and PHYTX 04 · Self Absorbed Moisturizer to keep it. The acid can wait until your skin is bored of being careful.
Every formula carries PhytoSpherix, a plant-derived glycogen that binds water at the surface. We measured what that does on 63 women aged 51 to 65, against a placebo cream: skin-surface hydration at +53.3% one hour after the first application (Study S-1180, corneometer), and +44.5% at six weeks.
That is a hydration outcome, measured on skin, and it is the only kind of promise we will make about a barrier that is already having a hard week.
