Here is a thorough breakdown based on your situation and the clinical literature:

Tretinoin 0.05% → 0.1%: Should You Step Up?

Your Current Situation

Age/Sex: 24-year-old male
Concern: Few blackheads (open comedones) and whiteheads (closed comedones) — mild comedonal acne
Current Rx: Tretinoin 0.025% → 0.05% (already at mid-strength)

What Tretinoin Does for Comedones

Tretinoin is a topical retinoid that works by:

Comedolytic action — normalizes follicular keratinization, unplugging existing comedones and preventing new ones
Anti-inflammatory effects
Improved dyspigmentation over time

It is a first-line treatment for comedonal acne per guidelines (Management of Acne Vulgaris, p. 8).

On Stepping Up to 0.1%

Short answer: Not necessary for your presentation, and the risk-benefit is unfavorable.

Factor	0.05%	0.1%
Efficacy for mild comedonal acne	Sufficient	Marginally better
Skin irritation, dryness, peeling	Moderate	Significantly higher
Retinoid dermatitis risk	Lower	Higher
Typical use case	General acne maintenance	Severe acne, photodamage, wrinkles

Key points:

0.05% is adequate for few blackheads/whiteheads. Tretinoin 0.1% is the highest available concentration and is primarily reserved for more severe acne, significant photodamage, or when lower concentrations have clearly failed after an adequate trial (typically 12–16 weeks).
Duration matters more than concentration at this stage. Tretinoin takes 8–12 weeks minimum to show full comedolytic effect. If you haven't used 0.05% for at least 3 months consistently, stepping up is premature.
0.1% carries a substantially higher side-effect burden: erythema, peeling, dryness, and post-inflammatory hyperpigmentation (especially relevant if you have darker skin). The irritation from 0.1% can paradoxically worsen acne in the short term ("purging" is more intense).
Tolerability comparison: Studies consistently show that higher tretinoin concentrations correlate with poorer tolerability without proportionally greater efficacy for mild acne (Galvin et al., Br J Dermatol, 1998, cited in Management of Acne Vulgaris, p. 26).

Recommended Approach

Instead of jumping to 0.1%, consider these steps first:

✅ Continue 0.05% for at least 12–16 weeks if you haven't already — full comedolytic effect takes time
✅ Optimize application technique: apply a pea-sized amount to dry skin 20–30 min after washing (reduces irritation)
✅ Add a non-comedogenic moisturizer nightly to buffer irritation and improve tolerance
✅ Consider a salicylic acid wash (2%) in the morning — complements tretinoin's comedolytic action
⚠️ Only step up to 0.1% if: you've used 0.05% for 4+ months with consistent application and see inadequate clearance, AND under guidance of a dermatologist

Bottom Line

For few blackheads and whiteheads in a 24-year-old, 0.05% tretinoin is the right tool — stepping to 0.1% is overkill and likely to cause more irritation than benefit. Give your current regimen a full therapeutic trial before escalating. A dermatologist can assess in-person if you're not seeing adequate results at the 3–4 month mark.

I have used almost more than a year but marks and new comedone are common like weekly one

This changes the picture significantly. After 1+ year on 0.05% with persistent weekly new comedones and marks, you've had a full and adequate trial — escalation and/or regimen addition is now clearly justified.

Your Situation: Tretinoin Plateau After 1+ Year

What's Happening

After 12+ months, if you're still getting:

Weekly new comedones → tretinoin 0.05% alone is not providing adequate comedolytic control
Persistent marks (post-inflammatory hyperpigmentation/PIH) → each new comedone is adding to cumulative pigmentation

This is a legitimate treatment plateau and your regimen needs to be stepped up.

Options: What to Do Next

Option 1 — Step Up to Tretinoin 0.1% ✅ Reasonable Now

After a 1+ year trial at 0.05%, stepping to 0.1% is now clinically appropriate. Your skin has also had extensive time to build retinoid tolerance, meaning you're far less likely to suffer severe irritation than a new user would.

How to transition safely:

Step	What to Do
Week 1–2	Apply 0.1% every other night, not every night
Week 3–4	Move to every night if tolerating well
Ongoing	Pea-sized amount on dry skin, 20–30 min post-wash
Must-do	Use a good non-comedogenic moisturizer every night over it

Expected benefit: Stronger comedolytic effect, faster comedone turnover, and tretinoin at 0.1% also has better evidence for improving PIH/marks (Management of Acne Vulgaris, p. 8).

Option 2 — Add a Complementary Agent (Can Do Alongside 0.1%)

Tretinoin alone often plateaus. Combining it addresses acne from multiple angles:

Agent	Role	When to Use
Salicylic acid 2% wash (morning)	Exfoliates follicles, reduces comedones	Morning cleanser, daily
Niacinamide 5–10% serum (morning)	Reduces PIH/marks, anti-inflammatory	Morning after wash
Azelaic acid 15–20% (morning or alternate nights)	Reduces PIH + comedolytic + anti-inflammatory	Great add-on for marks specifically
Benzoyl peroxide 2.5–5% (morning)	Prevents new comedone-to-pimple conversion	Use in AM, never same time as tretinoin

⚠️ Do not apply benzoyl peroxide and tretinoin at the same time — they oxidize each other. BP in the morning, tretinoin at night.

Option 3 — Consider Oral Treatment if Topicals Keep Failing

If even 0.1% + combination topicals don't control weekly new comedones over the next 3–4 months:

Low-dose oral isotretinoin (0.1–0.2 mg/kg/day) is highly effective for persistent comedonal acne that doesn't respond to topical retinoids — this would require a dermatologist prescription
Oral spironolactone is used in females; not applicable to you as a male

The Marks Issue Specifically

Persistent PIH from recurring comedones won't fully resolve as long as new lesions keep forming. The two-pronged approach:

Stop new lesions → stronger retinoid (0.1%) + salicylic acid
Fade existing marks → niacinamide + azelaic acid + strict daily SPF 30–50 (sun exposure significantly worsens PIH — this is often the most neglected step)

Bottom Line

Given 1+ year at 0.05% with persistent weekly comedones and marks:

✅ Yes, step up to tretinoin 0.1% — it is now appropriate
✅ Add niacinamide + daily SPF for the marks
✅ Add salicylic acid wash in the morning for extra comedolytic action
🔁 If still not controlled in 3–4 months at 0.1%, see a dermatologist to discuss oral isotretinoin
