Acne isn’t just a teenage issue. For many women, breakouts become more persistent, more painful, and more unpredictable with age — especially during monthly fluctuations and the perimenopause years.
If you’re looking for “dermatologist acne treatment” or “how to fix hormonal acne”, you’re not alone. At No. 23 Skin, adult acne is one of the most common concerns we treat. Through our recent London Women’s Skin Health Survey, clear skin was the absolute priority for 62% of women, and 82% of women said their skin fluctuates with their hormones without necessarily knowing why.
The good news? Acne is highly treatable with the right approach.
Adult acne can be persistent, with onset during teenaged years, or late onset beginning after the age of 25 years. Acne in your 30s, 40s, or 50s is rarely simple. It’s often influenced by:
fluctuating hormones
stress + cortisol
sleep patterns
skincare irritation
inflammation
genetics
This is why over-the-counter solutions often fail — they’re not tailored to the root cause. We’ve all been there – spending a lot on products that we have been promised will help our acne.
A dermatologist can identify whether your acne is:
inflammatory acne
hormonal acne
cystic acne
comedonal acne
acne with rosacea overlap
acne driven by perimenopause
And each type needs a different and well thought through treatment plan.
Some types of acne — especially hormonal, deep, or cystic acne — need more than skincare alone.
When appropriate, your dermatologist will discuss clinic-led treatment pathways designed to:
calm inflammation
support hormonal balance
reduce painful flare-ups
minimise long-term scarring
restore skin clarity
These plans are tailored to your age, skin type, symptoms and lifestyle — ensuring you get safe, effective, long-term results.
Your dermatologist will create a personalised skincare plan using clinically proven ingredients that target:
inflammation
congestion
excess oil
pigmentation from old breakouts
These evidence-based ingredients may include:
retinoid-style exfoliators
barrier-strengthening formulas
anti-inflammatory actives
oil-regulating ingredients
brightening treatments for marks
All products recommended are suitable for long-term, safe use under expert guidance.
A revolutionary laser that targets the sebaceous glands to reduce oil production long-term.
Perfect for adult acne that hasn’t responded to traditional treatments.
For redness, pigmentation, and scarring associated with acne:
IPL
resurfacing lasers – such as CO2 for scarring
LED phototherapy
Dermatologist-led acne treatment usually takes 6–12 weeks, depending on severity and treatment type.
But results are long-lasting — and often life-changing.
Book a specialist appointment if you have:
persistent breakouts
cystic or painful acne
acne leaving marks or scarring
hormonal acne flare-ups
acne impacting your confidence
Early intervention prevents scarring and speeds up results.
