So your dermatologist has prescribed isotretinoin (most people still call it Accutane, even though that brand name was discontinued years ago). You probably heard the warnings about dryness, sensitivity, and all the things you cannot do while on it. Here is the thing: isotretinoin works by fundamentally changing how your skin produces oil. Your sebaceous glands shrink dramatically, which is exactly why it is so effective at treating severe acne. But that same mechanism means your skin, lips, and eyes are about to get very, very dry. The good news? With the right routine, you can manage the side effects and actually feel comfortable in your skin during treatment.
What is Actually Happening to Your Skin
Before we get into products, let us talk biology for a second. Isotretinoin is a derivative of vitamin A that targets your sebaceous glands, the tiny organs in your skin that produce sebum (oil). When you take isotretinoin, these glands shrink by up to 90%, which is why acne clears so effectively. Fewer oil-producing glands means fewer clogged pores and less food for acne-causing bacteria.
But here is the catch: sebum is not just about acne. It is also part of your skin’s natural moisture barrier. When sebum production drops, your skin loses its ability to retain water as efficiently. The stratum corneum (your skin’s outermost layer) becomes compromised, leading to transepidermal water loss. Translation: moisture escapes from your skin faster than it can be replaced, leaving you dry, flaky, and sometimes genuinely uncomfortable. This is fundamentally a barrier problem, similar to other forms of sensitivity but temporarily more severe.
Your lips get hit especially hard because they do not have sebaceous glands at all. They rely entirely on the oils from surrounding skin to stay moisturized. When that supply gets cut off, well, you will find out pretty quickly why lip care becomes non-negotiable during treatment.
The Minimal Routine That Actually Works
During isotretinoin treatment, less is genuinely more. Your skin becomes sensitized and reactive, so this is not the time to experiment with new actives or complicated multi-step routines. According to dermatologists at the American Academy of Dermatology, sticking to basics (cleanser, moisturizer, sunscreen) is the safest approach.
Morning routine:
- Gentle, non-foaming cleanser (skip anything with salicylic acid, benzoyl peroxide, or physical exfoliants)
- Hydrating serum with hyaluronic acid (optional but helpful)
- Rich moisturizer with ceramides
- SPF 30+ broad-spectrum sunscreen (this is non-negotiable)
Evening routine:
- Same gentle cleanser
- Hydrating serum if you are using one
- Heavier moisturizer or face oil
- Thick layer of lip balm
That is it. Seriously. No retinoids (you are already on the strongest one), no AHAs, no BHAs, no vitamin C serums that might cause irritation. Save all of that for after your course ends.
The Products That Actually Help
Look for moisturizers that contain ceramides, hyaluronic acid, or glycerin. These ingredients specifically target the barrier repair your skin desperately needs. Curology dermatologists specifically recommend products like CeraVe PM, La Roche-Posay Toleriane Double Repair, and Cetaphil Cream. All of these are fragrance-free and formulated for sensitive skin, which is exactly what you need.
For cleansing, micellar water or gentle milk cleansers work well. Avoid anything that foams aggressively or leaves your skin feeling squeaky clean. That squeaky feeling means you have stripped what little moisture barrier you have left.
Niacinamide is one of the few actives that is generally considered safe during isotretinoin treatment. It helps improve barrier function and reduce inflammation without causing additional irritation. If you want to add something extra to your routine, this is a reasonable choice.
Lip Care Is Not Optional
I cannot stress this enough: you need to be applying lip balm constantly. We are talking every one to two hours during the day, and a thick layer before bed. Your lips will crack, peel, and potentially bleed if you do not stay on top of this.
Dr. Dan’s CortiBalm is probably the most frequently recommended lip balm among isotretinoin users. It contains hydrocortisone, which helps reduce inflammation and speeds healing. Most people report significant improvement within 24 hours of starting to use it. For daily maintenance, Aquaphor and plain Vaseline work well as occlusives, meaning they create a physical barrier to seal in moisture.
Look for lip products containing humectants (like glycerin and hyaluronic acid) paired with occlusives (like beeswax, petroleum jelly, or shea butter). The humectants draw moisture in; the occlusives keep it from escaping. This combination is what your lips need when they are this compromised.
Avoid anything with camphor, menthol, or added fragrance. These ingredients can irritate already-damaged lips and make cracking worse. Keep a lip balm in every location: your bathroom, your bag, your desk, your nightstand. You will use them all.
Sun Sensitivity Is Real
Isotretinoin makes your skin significantly more photosensitive. You can burn faster and more severely than you normally would, even on cloudy days or through car windows. The American Academy of Dermatology recommends SPF 30 or higher, worn daily, reapplied every two hours if you are outdoors.
Mineral sunscreens (containing zinc oxide or titanium dioxide) are often better tolerated than chemical sunscreens during treatment because they are less likely to cause irritation. If you are going to be outside for extended periods, wear a hat and seek shade when possible. This is not about vanity; sunburn on isotretinoin-compromised skin is genuinely painful and can lead to longer-lasting damage.
Do not forget about incidental sun exposure. Driving, walking to lunch, sitting near windows: it all adds up. Make sunscreen part of your morning routine regardless of your plans for the day.
Things You Absolutely Cannot Do
Waxing is off the table during your entire course and for at least six months afterward. Isotretinoin thins your skin, and waxing can literally rip it off. This applies to facial waxing, eyebrow waxing, leg waxing, all of it. Threading and tweezing are okay for eyebrows, or you can shave. But no wax.
Laser treatments, chemical peels, and microdermabrasion should also wait. Most dermatologists recommend waiting 6-12 months after completing your isotretinoin course before doing any of these procedures. Your skin needs time to rebuild its normal barrier function first.
Avoid vitamin A supplements (you are getting plenty through your medication) and be cautious about excessive alcohol consumption, as isotretinoin is processed through your liver. Your dermatologist will be monitoring your blood work throughout treatment, so follow their guidance.
Dealing with Body Dryness
It is not just your face that gets dry. Your entire body, especially your arms and legs, can become flaky and itchy. Apply a rich body moisturizer immediately after showering while your skin is still slightly damp. This helps lock in moisture more effectively than applying to dry skin.
Take lukewarm showers instead of hot ones. Hot water strips away your skin’s natural oils, which is the last thing you need when you are already running on empty. Keep showers short, pat dry gently instead of rubbing, and moisturize within three minutes of getting out.
Your hands might crack, especially around the knuckles. Keep hand cream at every sink and apply it after washing. Cuticle oil can help keep your nails and surrounding skin from becoming painful.
What Happens After Treatment Ends
The dryness does not disappear the moment you take your last pill. Most people find that their skin takes several months to return to its baseline oil production. Continue your gentle, hydrating routine during this transition period.
About 30 days after finishing your course, you can typically start reintroducing other actives. Many dermatologists recommend starting with a prescription retinoid like tretinoin to maintain your clear skin. But wait at least six months before scheduling any laser treatments or aggressive procedures, and always confirm with your dermatologist before adding anything new.
The good news is that by the time you finish treatment, you will have learned a lot about your skin and what it actually needs. Many people find that the habits they developed during isotretinoin, like wearing sunscreen daily and keeping their routine simple, stick with them long after treatment ends. And honestly, those are habits worth keeping.
