Cosmetic creams and home remedies (essential oils, honey masks, supermarket supplements) can slightly improve skin or scalp quality, but do not act on the underlying causes of acne scars or hair loss. Atrophic scars are structural dermal lesions; androgenetic hair loss results from a hormonal disruption targeting hair follicles. Both problems require action deeper than cosmetic molecules can reach.
Why can creams not treat acne scars?
Creams cannot correct a true indented acne scar because it represents a deep change in dermal structure rather than a simple surface imperfection.
When acne inflammation reaches deep skin layers, healing may not rebuild tissue evenly. Atrophic scars notably appear when collagen production during healing is insufficient: tissue loss creates a visible depression at the surface.
These scars involve the reticular dermis and may extend several millimetres deep according to severity. Cream ingredients, even retinol, vitamin C or hyaluronic acid formulations, do not reach these deep structures at concentrations that rebuild lost tissue. A cream therefore cannot fill an indented scar or restore dermal architecture destroyed by acne.
Topical products nevertheless remain useful: they can improve hydration and superficial texture, and certain ingredients soften post-inflammatory hyperpigmentation left by acne lesions.
Superficial acne marks, which certain products can improve, must therefore be distinguished from true acne scars requiring care that acts deeper in skin tissue.
Which treatments are effective for acne scars?
There are several types of acne scars: pigmented scars (red or brown), ice-pick scars, atrophic scars, the most common in severe acne, and raised hypertrophic scars. Each type needs a different therapeutic strategy.
Treatments that genuinely act on scar structure reach the dermis to induce collagen remodelling.
• Fractional laser (Erbium, CO₂) ablates microscopic dermal columns, stimulating new collagen formation. It remains a reference treatment for moderate to severe atrophic scars.
• PRP strengthens stimulation of new collagen formation.
• Deep laser/chemical peels (TCA, high-concentration glycolic acid) exfoliate superficial and deep skin layers and induce dermal remodelling under strict medical supervision.
• Subcision is indicated for fibrous scars attached to deeper layers. This technique mechanically severs subcutaneous bands.
• Fillers (hyaluronic acid, Sculptra) can temporarily fill indented scars.
Options such as laser resurfacing, chemical peels or PRP injections stimulate collagen production and visibly improve skin texture.
These treatments require prior skin assessment to identify scar type and depth, adapt delivered energy and plan sessions according to individual response.
Why do home remedies not stop hair loss?
Hair loss, particularly androgenetic alopecia accounting for the vast majority of cases, follows a specific hormonal mechanism: dihydrotestosterone (DHT) gradually miniaturises hair follicles until they cease functioning.
Commonly cited home remedies (castor oil, onions, scalp massage, zinc or biotin supplements) may improve existing hair quality or correct a mild nutritional deficiency. They have no demonstrated effect on DHT or follicular miniaturisation. Achieving results similar to minoxidil or finasteride requires relying on a combination of products whose effects are not always scientifically proven.
The difference from validated medical treatments is documented:
• Minoxidil lotion is the only validated topical treatment. Effective in around 60 % of cases, it slows hair loss by acting on local blood supply.
• Finasteride can stop hair loss in around 86 % of men and promote regrowth in around 65 % of them.
These molecules act on targeted biological mechanisms: one on follicular blood flow, the other on DHT production. No home remedy reproduces these effects.
Hair loss: when should you consult and which treatments should be considered?
The most common mistake is waiting. Androgenetic hair loss progresses: the more miniaturised follicles become, the harder they are to reactivate. Early consultation assesses the alopecia stage (Hamilton–Norwood classification for men, Ludwig for women) and guides suitable treatment.
Medical options available in Geneva are:
• Hair PRP: platelet-rich plasma injections directly into the scalp to stimulate still-active follicles. Usual protocol: 3 to 4 sessions a month apart, with maintenance every six months.
• Topical minoxidil prescribed by a doctor with dosage adjustment.
• Hair mesotherapy: intradermal injections of active cocktails (vitamins, amino acids, growth factors) to nourish the hair bulb directly.
• Finasteride + minoxidil: finasteride is considered more potent at stopping loss, while minoxidil is excellent for increasing density in thinning areas. The treatments complement each other.
Who is a good candidate?
Anyone with progressive, visible loss lasting more than six months and still-functional follicles. PRP and minoxidil can also be used in women; finasteride is reserved for men.
When is a hair transplant necessary?
When alopecia is scarring (lichen planopilaris, lupus) or follicles are permanently destroyed, only hair transplantation can restore density.
Key points before choosing treatment
Creams and home remedies are not inherently useless: they may form part of a comprehensive protocol as maintenance skincare or preparation. But they do not replace medical treatment when the problem is structural or hormonal.
For acne scars, medical assessment classifies lesions and selects the technique most suited to depth and type. For hair loss, time is decisive: the earlier care begins, the more significant the results.
A consultation in Geneva provides a personalised assessment and precise diagnosis.
Why is improvement sometimes observed nevertheless?
Some people notice improvement after using a cream or home remedy.
This often reflects several factors: improved hydration, reduced irritation, temporarily improved texture, a cosmetic effect associated with light or hydration, or natural progression of the condition.
For hair, certain products make the fibre shinier, more supple and thicker without increasing the actual number of hairs or slowing hair loss.
Distinguishing temporary aesthetic improvement from genuine correction of the underlying problem is therefore important.
