It is not because you are not washing your face. If anything, most of us with hormonal acne have washed our faces considerably more than the situation called for.
Cystic breakouts along the jaw, chin and neck have a hormonal address, and no amount of cleanser reaches it from the outside.
The androgen pathway
Androgens stimulate your sebaceous glands to produce more sebum, and to produce a thicker, stickier kind. That sebum plugs the follicle. Cutibacterium acnes, which lives on everyone’s skin quite peacefully, overgrows in the trapped, oxygen-poor environment. The inflammation that follows is what produces deep, painful lesions rather than surface whiteheads.
The distribution is the clue. Sebaceous glands along the lower face, jaw and neck are more androgen-sensitive than those elsewhere, which is why this is where it shows up and why it is called hormonal acne rather than teenage acne.
Why insulin belongs in a skin article
Insulin and IGF-1 both increase ovarian androgen production and lower sex hormone binding globulin, the protein that keeps testosterone bound and inactive. Less SHBG means more free testosterone in circulation.
So blood sugar sits upstream of the thing causing your breakouts. This is why skincare alone plateaus, and why the mechanism in insulin resistance without a diabetes diagnosis is worth understanding even if your skin is your only complaint.
You cannot topically treat a hormonal signal. You can support the skin while you change the signal.
The four-step routine
One: blood sugar. Protein at breakfast, fibre before starch, a walk after your largest meal. Unglamorous, free, and upstream of everything else here.
Two: a boring topical routine. Gentle non-foaming cleanser, a leave-on salicylic acid two or three nights a week, a proper moisturiser, and daily SPF. Salicylic acid is oil-soluble, so it gets into the pore where the problem is — unlike glycolic, which works on the surface.
Not eight actives. Barrier damage from over-treating causes its own inflammation and is one of the most common ways people make this worse while trying hard.
Three: give it twelve weeks. Skin turns over on roughly a 28-day cycle and inflamed lesions resolve slowly. Two weeks tells you nothing except whether something irritates you.
Four: consider the internal levers. Spearmint has two small trials showing reduced free testosterone. Zinc has modest evidence for inflammatory acne. Both are slow. A dermatologist can discuss options that act directly on the androgen pathway, which is a legitimate and often underused route.
What made the biggest difference for me
Fourteen months, and accepting that no serum was going to fix a hormonal problem from the outside. The order that worked was blood sugar first, sleep second, then a simplified routine, then the internal supports.
I wasted about two years on the reverse order, which is the order the beauty industry sells.
Questions people actually ask
Should I stop using makeup?
No. Non-comedogenic formulas are fine and the psychological benefit is real. Remove it properly and do not add a harsh cleanser to compensate.
Does dairy cause hormonal acne?
The evidence is weaker than the internet suggests, and skim milk carries more of it than cheese or yoghurt. How to test it properly is in the dairy article.
Is it worth seeing a dermatologist?
Yes, particularly if you have scarring or lesions lasting weeks. Scarring is preventable and permanent, which makes it worth escalating early rather than experimenting for another year.
Will the pill fix it?
It often suppresses it effectively while you take it. What happens afterwards is covered in coming off the pill.
