Accutane and Isotretinoin
Mega Guide
This guide is meant for people who are currently taking isotretinoin or are considering starting it. In this guide im gonna explain u everything in one place: Mega Guide
- how dosing actually works
- what side effects to expect
- how long the treatment should last
- how to reduce side effects
1. What Accutane (Isotretinoin) actually is
Isotretinoin is the strongest acne medication currently available. It works through several mechanisms:
• Reduces oil production
• Decreases acne-causing bacteria
• Normalizes skin cell turnover
Because of this, isotretinoin can permanently clear acne in around 80–90% of patients after a full course.
2. The most important concept: Cumulative dose
One of the biggest misunderstandings about isotretinoin is dosing. Many people think the treatment depends on daily dose.
But in reality, derms focus on total cumulative dose over the entire treatment.
Most dermatology guidelines recommend a cumulative dose of:
120–150 mg per kilogram of body weight
Example calculation:
If someone weighs 70 kg
70 × 120 = 8400 mg
70 × 150 = 10500 mg
So the total course should reach around 8400–10500 mg.
Stopping treatment before reaching this cumulative dose significantly increases the risk of acne relapse.
3. Typical isotretinoin dosing strategies
There are generally three dosing approaches used by dermatologists.
Low-dose Protocol
0.1 – 0.3 mg/kg/day
Pros:
• fewer side effects
• easier to tolerate
Cons:
• longer treatment duration (sometimes up to 12–18 months)
Standart Protocol
0.5 – 1 mg/kg/day
Example:
70 kg person: 35 – 70 mg per day
Typical treatment length: 4–6 months.
High-dose Protocol
Up to 2 mg/kg/day
Usually used for severe nodulocystic acne.
Higher doses may reduce relapse rates but usually increase side effects.
4. Isotretinoin dosing table by body weight
| Weight | Low dose | Standard dose | High dose |
|---|---|---|---|
| 50 kg | 15 mg/day | 25 mg/day | 50 mg/day |
| 60 kg | 20 mg/day | 30 mg/day | 60 mg/day |
| 70 kg | 20–25 mg/day | 35 mg/day | 70 mg/day |
| 80 kg | 25 mg/day | 40 mg/day | 80 mg/day |
| 90 kg | 30 mg/day | 45 mg/day | 90 mg/day |
| 100 kg | 30–35 mg/day | 50 mg/day | 100 mg/day |
Example:
Someones weight = 70 kg
Target cumulative dose:
8400 – 10500 mg
If someone takes 40 mg per day
8400 ÷ 40 = 210 days
10500 ÷ 40 = 262 days
Estimated treatment duration:
7–9 months
(This is exactly the way for u or ur derm to calculate the cumulative dose)
6. What to expect month by month
Many people panic because they don't know what the treatment timeline looks like.
Here’s the typical progression:
| Month | What Usually Happens |
|---|---|
| Month 1 | Most people start experiencing very dry lips, dry skin, dry nose, and irritation. Many patients go through a purge phase, where acne temporarily gets worse. This happens because isotretinoin accelerates skin cell turnover and pushes clogged pores to the surface faster. |
| Month | What Usually Happens |
|---|---|
| Month 2–3 | Oil production begins to drop significantly. Breakouts become less frequent, and skin becomes noticeably less greasy. Dryness usually becomes more noticeable during this period. |
| Month | What Usually Happens |
|---|---|
| Month 4–5 | Many patients become almost completely clear at this stage. Remaining issues may include redness or post-acne marks rather than active acne. |
| Month | What Usually Happens |
|---|---|
| Month 6+ | Once the target cumulative dose is reached, treatment usually ends. Skin may continue improving for 1–2 months after finishing the medication. |
7. Things you should always do on Accutane
Moisturize aggressivelyBecause ur skin barrier becomes very fragile. U MUST-HAVE products like:
U should definitely have lip balm or even just vaseline, otherwise ur lips will get so dry and start bleeding
Then we go to moisturizer. U can buy any other good moisturizers, but i would recommend u to buy these products
Next, it's crucial to buy a good SPF, as u simply can't go outside without it. Most importantly, don't forget to reapply it every 2-3 hours if u do go outside. Buy 50+ SPF. In my case its La Roche-Posay
Also u should have any topical tretinoins. This will help ur skin actively get rid of pimples that will appear for the first 2 months. (U CAN USE IT ONLY AT NIGHT)
Take isotretinoin with food
Isotretinoin is fat soluble. Taking it with food significantly improves absorption
In other words, without fat you may be missing out on approximately 50-60% of your intake
8. Basic Skincare Routine on Isotretinoin
Your skin becomes much more sensitive and fragile during treatment because isotretinoin dramatically reduces oil production and weakens the skin barrier.if u keep using the same aggressive products u used before, u will likely end up with:
• irritation
• redness
• burning skin
• extreme dryness
Ur routine should stay very simple.
Morning routine:
1. Gentle cleanser (U also can wash ur face with water)
2. Moisturizer (then wait for 15min)
3. SPF
Night routine:
1. Gentle cleanser
2. Topical Tretinoin (be sure to wait 15-20 minutes for the tretinoin to be absorbed fully)
3. Moisturizer
That’s usually enough. Also dont forget about lip balm, u need to reapply it every hour.
Overcomplicating ur routine while on isotretinoin often makes things worse
9. Will acne come back?
Statistics suggest:• around two thirds of patients remain clear long term
• around one third may need another course
So, after u complete the course, u and ur derm wait a month for clear skin. Basically, u're doing absolutely nothing for ur skin. it's supposed to stay clear forever, and then u'll go into remission. Don't forget that acne is a chronic condition that has no cure, and if even a course of systemic retinoids doesn't help, it's all down to ur genetics. So yeah, that’s basically everything u must learned about isotretinoin and what to expect during the course.
