How to identify your type of acne to choose the right active ingredients

You have pimples. Maybe for a long time. You've tried products, routines, advice. Some worked for a while. Nothing has really solved the problem permanently.

The main reason: not all acne is the same. And treating hormonal acne like comedonal acne is chasing a result that won't come.

Identifying your acne type is not a detail. It's the condition for choosing the right active ingredients.

What's really happening in your skin

Acne is a pathology of the pilosebaceous follicle. Three mechanisms combine: hypersecretion of sebum stimulated by androgens, hyperkeratinization that obstructs the follicular canal, and proliferation of the bacterium Cutibacterium acnes in this anaerobic and lipid-rich environment. The ensuing inflammatory reaction produces visible lesions: comedones, papules, pustules, nodules, cysts.

These three mechanisms are not always present with the same intensity. This is what differentiates the types of acne and determines the relevant active ingredients for each.

The different types of acne: how to recognize them

Comedonal acne (retentional acne) is dominated by blackheads (open comedones) and microcysts (closed comedones). Little or no visible inflammation. The skin is oily, pores are dilated. This is often the initial stage, common in adolescents, but also present in adults. The main problem is follicular obstruction, not bacteria.

Inflammatory acne is characterized by papules (red pimples) and pustules (white pus-filled pimples), painful to the touch. The bacterium Cutibacterium acnes triggers a local immune reaction. It can coexist with a comedonal component. It is the most common form and the one that leaves the most marks if not properly managed.

Nodulocystic acne is the severe form: hard, deep, painful nodules, large cysts. It requires medical management. It leaves depressed scars and persistent hyperpigmentation. Cosmetic care alone is insufficient.

Hormonal acne primarily affects adult women. It is localized on the lower face, chin, and jawline. It follows a cyclical rhythm, with a flare-up 7 to 10 days before menstruation, linked to androgen fluctuations. The pimples are often deep, inflammatory, few in number but recurrent. It is resistant to classic topical treatments if the hormonal component is not addressed.

Why treatments often fail in adults

Adult acne (after 25) is often poorly managed because the same approaches as adolescent acne are applied to it. However, it is biologically different: fewer but deeper lesions, more inflammatory, on skin that tolerates aggressive active ingredients less well. Adult acne-prone skin often has a weakened skin barrier in parallel, which makes stripping treatments counterproductive.

Adding increasingly powerful active ingredients to already irritated skin maintains inflammation instead of reducing it. This is the most common vicious circle in the management of adult acne.

Validated active ingredients according to acne type

For comedonal acne, topical retinoids are the reference: they regulate cell renewal and unclog follicles. Salicylic acid (liposoluble BHA, up to 2% in cosmetics according to European regulations) penetrates the pore and dissolves sebaceous obstructions. It is keratolytic, comedolytic and slightly anti-inflammatory.

For inflammatory acne, benzoyl peroxide is the reference over-the-counter antibacterial active ingredient. It releases oxygen on contact with the skin, which is lethal for Cutibacterium acnes. Effective between 2.5 and 5% with acceptable tolerance. Niacinamide at 4-5% reduces local inflammation and sebum production without damaging the barrier. Azelaic acid combines antibacterial, anti-inflammatory and depigmenting action, particularly useful when acne is accompanied by spots.

For hormonal acne, topical treatments alone provide limited results if the hormonal cause is not treated. A medical consultation is necessary to evaluate suitable contraception or anti-androgen treatment. In addition, oral zinc gluconate is documented for its action on sebaceous regulation and inflammation. A systematic review published in the Journal of Drugs in Dermatology, and a meta-analysis published in Dermatologic Therapy, document its effect on mild to moderate inflammatory lesions, while noting a moderate level of evidence.

For nodulocystic acne, a dermatological consultation is essential. Oral isotretinoin remains the reference treatment for severe forms. Cosmetic care plays a supportive role, not a primary treatment.

Mistakes that worsen acne instead of treating it

Over-exfoliating acne-prone skin is the most common mistake. Daily glycolic acid, high-frequency salicylic acid, benzoyl peroxide and retinol at the same time: this accumulation weakens the barrier, increases inflammation and triggers post-inflammatory hyperpigmentation that is difficult to correct.

Neglecting hydration because the skin is oily is another common mistake. Dehydrated skin overcompensates by producing more sebum. A light, non-comedogenic moisturizer is an integral part of any effective anti-acne routine.

Changing treatments every two weeks prevents anything from being evaluated. Anti-acne active ingredients take at least 6 to 8 weeks to show their effects. Regularity is a condition for results.

The Paradermia Approach

Our pharmacist adapts each protocol to the type of acne and the actual skin profile. Active ingredients are selected for their actual formulation and their relevance to the mechanism involved, not for their popularity. Products are integrated into a coherent routine where each step has a precise role, without overloading already weakened skin.

Frequently Asked Questions

Can I find an anti-acne routine adapted to my acne type on Paradermia?
Yes. Our pharmacist offers differentiated protocols according to the type of acne: comedonal, inflammatory, hormonal or adult acne. Each recommendation takes into account your skin profile, your tolerance and your objectives to build a coherent and progressive approach.

Should I see a doctor for my acne?
For mild to moderate forms, management with adapted care may be sufficient. For resistant hormonal acne, nodulocystic acne or acne that leaves deep scars, a dermatological consultation is recommended. Paradermia care can accompany medical treatment or constitute a first approach for mild forms.

Why does my acne worsen with certain treatments?
Powerful anti-acne active ingredients applied to an already weakened skin barrier aggravate inflammation instead of reducing it. An initial shedding (slight flare-up) is normal with certain active ingredients such as retinol. But a persistent worsening after 3 to 4 weeks generally indicates that the concentration is too high or that the active ingredients do not correspond to your acne type.
