I’ve been using Tretinoin 0.5 for 5 months, only gentle skincare with it - Is my skin dehydrated? (photos)

Thank you for your question. It is difficult to tell from pictures what sort of skincare you may need. I suggest making an appointment for a consultation with a skin specialist for an in-person examination and to discuss further. Best of luck!

Thank you, Selena8245 for your question and photographs.
Photographic evaluation is incomplete without personal examination to give the most appropriate answer
However from the photographs, it seems that,
Your skin has become dehydrated due to long-term usage of Tretinoin. You can stop applying it for a brief amount of time and see the effect. Also please apply a lot of moisturizers according to your skin type in order to restore hydration. If you wish to begin your Tretinoin treatment again then use Short Contact mode i.e apply it for 2 hours and then rinse it off.

Please consult a board-certified dermatologist near you and discuss this in detail.
Wish you an alluring look.

thanks for the pics, once u use tretinoin two things need to be taken care of, one is regular moisturising of your face and lips. second most important is that u need to apply sunscreen at least 3 times a day with spf 50 (minimum) even if u working or staying at home and not going out. secondly check if u have any hormonal issues like pcos or thyroid.
let me know if this helps
