Hello. Thanks for writing to us at healthcaremagic

I am Dr. Kakkar. I have gone through your query.

Judging from the history and treatments tried I can make out that the dark spots are probably due to acne (Post-Inflammatory Hyperpigmentation)

-I would like to know whether do you still have acne?
-Are you still taking Isotretinoin? and the face wash that you mentioned?
-Dazit is an antihistamine/antiallergic. Can you briefly tell about any that you have?
-Is the sunscreen that you are using too oily or greasy?

Your first concern is dark circles. It is a difficult proposition to treat dark circles because the darkening is actually not due to excess pigment as is commonly believed. However, skin lightening agents do seem to help in some.

Hereditary seems to play a significant role in dark circles. In allergy prone individuals, a condition or state of 'atopy' exists & these atopic individuals more often than not manifest with 'dark circles' under the eyes.

Dark circles also depends a lot on your lifestyle pattern--diet, sleep, computer / TV use and stress.
Stressors/ Eyestrain due to working for long hours on computers & lack of sleep play a major role too as do Lack of regular and adequate sleep (6-8 hours).

In some individuals dark circles may be due to thin under eye skin; thin skin makes the blood in the blood vessels shine through and hence this appears dark.

Another important cause of undereye dark circles is Iron deficiency Anemia.

Skin lightening creams containing glycolic acid, kojic acid, Vit C can be helpful in reducing the appearance of dark circles. The same creams would also work for Post-inflammatory Hyperpigmentation on face.

Glycolic acid and Arginine peels are the two commonly used peels by dermatologists for undereye dark circles. You can try a few peeling sessions (6-8 sessions).

As can be judged from some of the reasons cited, good hydration, regular 6-8 hours of sleep, addressing stressors and a multivitamin and Iron supplement by themselves will go a long way in correcting this issue

Your another concern is that you skin gets too oily in summers and dry in winters. I would suggest that you may use a gentle cleanser or face wash, twice daily e.g cetaphil cleansing lotion. The face wash that you mention in the treatment section contains glycolic acd+salicylic acid and can cause severe dryness specially in winters.
Furthermore the more you dry up your face there will be compensatory/rebound oiliness.

Regarding dullness on face, I assure you that most of it is due to the dark spots (PIH) due to acne. Once the spots are adequately taken care of, you will notice the difference.

Post Inflammatory Hyperpigmentation can be greatly improved by either Chemical peeling sessions (specifically glycolic peel) Or with topical skin lightening cream containing one or more of the following skin lightening ingredients like Azaleic acid, Hydroquinone, Kojic acid, Arbutin etc

Oral Isotretinoin can make facial skin sensitive to sun exposure; it may turn red if you are outdoors in the sun for a long time. Flushing is also a side effect of Isotretinoin.
You may continue with the same sunscreen. Use it every 2-3 hours whenever you are outdoors.

Kindly get back to me with the details so that I am able to guide you better.
You can also get back to me for any clarifications

Detailed Answer:
Hi.

-You should use a gentle cleanser for face wash e.g cetaphil cleansing lotion, twice daily.
-For dryness you may use a non-comedogenic moisturizer e.g cetaphil -moisturizing cream.
-Continue with Isotretinoin for the duration as advised by your dermatologist as well as sunscreen as advised by your dermatologist.
-For dark spots you may use either Azaleic acid twice daily, rub it in gently Or Kojic acid, twice daily. I can only provide you generic names and options through this forum. Your dermatologist after proper visual assessment would prescribe you the cream that would be best suitable for you
-You can inquire about chemical peels from your treating dermatologist. A session of glycolic peel once every 2 weeks would be suitable for dark spots/ pigmentation.
They are not home peels and you need to visit a dermatologist for a session.
