Acne Treatment: What Actually Works According to Dermatologists

Acne is the most common skin condition worldwide, affecting roughly 85% of people between ages 12 and 24 — and many adults well beyond that. With countless products claiming miracle results, it can be overwhelming to know what actually works. This guide cuts through the noise with evidence-based treatments that dermatologists consistently recommend.

Understanding Why Acne Happens

Acne develops when four factors combine: excess sebum production, clogged pores from dead skin cells, bacterial overgrowth (particularly Cutibacterium acnes), and inflammation. Effective treatment targets one or more of these root causes rather than just masking symptoms.

Hormonal fluctuations, stress, diet, and genetics all play a role in how severe your breakouts become. Understanding your specific triggers is the first step toward building a routine that delivers real results.

Proven Active Ingredients for Acne

Retinoids: The Gold Standard

Retinoids (vitamin A derivatives) are considered the cornerstone of acne treatment by dermatologists worldwide. They work by accelerating cell turnover, preventing pores from clogging, and reducing inflammation. Products containing retinol — like the Infinity Treato Serum SPF 30 — combine acne-fighting retinoid action with sun protection, which is critical since retinoids can increase photosensitivity.

For those new to retinoids, start with a lower concentration and gradually increase frequency. Apply at night, and always pair with SPF during the day.

Niacinamide (Vitamin B3)

Niacinamide helps regulate sebum production, reduce inflammation, and strengthen the skin barrier. It's well-tolerated by most skin types and pairs effectively with retinoids. Look for products that combine retinol with niacinamide — such as the Retinol B3 Cream — for a synergistic approach to both treating and preventing breakouts.

Salicylic Acid (BHA)

This beta-hydroxy acid penetrates oil-filled pores to dissolve the debris causing blockages. It's ideal for blackheads and whiteheads and works best at concentrations of 0.5–2%. Use it as a cleanser or leave-on treatment, but avoid combining it with too many other actives at once.

Benzoyl Peroxide

Benzoyl peroxide kills acne-causing bacteria and is available over the counter in concentrations from 2.5% to 10%. Research shows that 2.5% is often just as effective as higher concentrations but with less irritation. Apply as a spot treatment or short-contact wash.

Building an Acne-Fighting Skincare Routine

Morning Routine

1. Gentle Cleanser — Start with a mild, non-stripping cleanser. Harsh cleansers can trigger more oil production and worsen breakouts. The Hyalu Collagen Cleansing Foam provides thorough cleansing without disrupting the skin barrier.
2. Treatment Serum — Apply a niacinamide or vitamin C serum to reduce redness and protect against environmental damage.
3. Lightweight Moisturizer — Even oily, acne-prone skin needs hydration. Skipping moisturizer can trigger compensatory oil production. The Infinity Moisturizing Cream provides hydration without clogging pores.
4. SPF 30+ — Non-negotiable, especially if using retinoids or acids. The Treato Serum SPF 30 doubles as both treatment and sun protection.

Evening Routine

1. Double Cleanse — Remove sunscreen and makeup with an oil-based cleanser first, then follow with a water-based cleanser.
2. Active Treatment — This is when you apply your retinoid or chemical exfoliant. Don't use both on the same night — alternate between them.
3. Moisturizer — Lock in hydration and support barrier repair while you sleep.

Common Mistakes That Make Acne Worse

Over-washing and over-exfoliating. Cleansing more than twice daily strips the skin, triggering rebound oil production. Similarly, using too many active ingredients simultaneously damages the barrier and increases inflammation.

Skipping moisturizer. The myth that oily skin doesn't need moisturizer persists, but dehydrated skin produces more sebum. Use a lightweight, non-comedogenic formula.

Picking and popping. This introduces bacteria deeper into the skin, creates scarring, and prolongs healing time. Resist the urge — use a hydrocolloid patch instead.

Inconsistency. Most acne treatments take 6–12 weeks to show significant results. Switching products every two weeks prevents any single treatment from working properly.

Treating Acne Scars and Hyperpigmentation

Post-inflammatory hyperpigmentation (PIH) — the dark spots left behind after breakouts — is often more frustrating than the acne itself. Retinoids, niacinamide, and vitamin C all help fade these marks over time. The Treato Cream specifically targets skin renewal and can support the fading process when used consistently.

For deeper scarring, professional treatments like chemical peels, microneedling, or laser therapy may be necessary. Consult a dermatologist for personalised advice.

When to See a Dermatologist

If over-the-counter products haven't improved your acne after 8–12 weeks of consistent use, it's time for professional help. Cystic acne, hormonal acne, and acne that's causing scarring all benefit from prescription-strength treatments that a dermatologist can provide.

The Bottom Line

Effective acne treatment isn't about buying every product on the shelf — it's about using the right ingredients consistently. A simple routine built around proven actives like retinoids, niacinamide, and gentle cleansing will outperform any complicated 10-step regimen.
