tretinoin or tazarotene

Tretinoin has a longer track record for "anti-aging" and is less harsh than tazarotene

Both are fine

ymmv
I know tret’s supposed to be easier to tolerate, but taz was better for me. It made positive improvements faster than tret did.
i used to use 0.05% tret (didnt feel anything) so i was gonna move up to 0.1% but it isnt sold in my country when i checked here i found out option to get tret or taza just not sure what should i go for

What are you looking to "feel" with either?

You don't really feel a reduction in fine lines & aging spots (might not even see them either)

You might get some discomfort/redness with both the first few days
 
Have used tretinoin for many years for anti-aging skin purposes.

Works very well and you really do not need the higher strength ones (0.025% is plenty)

I did try the higher strength ones (0.05% and 0.10%) for a few months to test further effectiveness but they were very harsh.

Also worth noting that you will need a moisturiser in the mornings. Find one with a high amount of hyaluronic acid (better for retaining moisture in skin) as that will also help to reduce the skin redness that you usually get for the first few months.

im not looking to "feel" anything just wanna know which one i should get i understood taza is newer just not sure its better
 
Taz is newer and stronger, so it will be harsher on your skin (especially so when starting) but will deliver results faster than tret the same way a higher % tret will be harsher and deliver faster than a lower % tret (0.025% vs 0.05% vs 0.1%)

All in all the end goal should be the same, it will just have different timelines so you should just stick to whatever your skin agrees with and be consistent and not try to go the fastest possible

Like PEDS when you think about it

It is newer but not necessary stronger and harsher.
It works differently and cannot be compared this way.

Tret is a machine gun that hits everything.
Taz is a sniper that hits specific targets.

I use 0.1% Taz. I did not like Tret -- I had more sides on a lower % Tret than higher % Taz.

This was my experience. Taz was way more gentle on my skin than tret ever was. It was so significantly better that when my son wanted to use a retinol, I had him use Taz. He had none of the negatives associated with beginning and was able to move to daily use quickly.
 
It is stronger for anti-aging than tret as it has a higher binding affinity to the collagen production area, which is what's needed for wringles and photodamage unlike tret that activates other receptors as well.

It would be like comparing semaglutide and tirzepatide.

It is also better tolerated on average BUT if you are sensitive to it, it is going to be way harsher side effects wise than tret (source me: I had dryness/redness at the start with tret and when I tried low taz my skin started fucking peeling a week in).

So as everything, YMMV.
In theory without issues, Taz would be better, but in practice use what you can get and tolerate.

Also Tret as A LOT MORE long-term studies
