TirtirAzelaic Acid 12% Serum

I bought this serum for my daughter with hormonal acne. I have to say that the serum doesn't irritate, it's really gentle and she could use it every day from the start. It mattifies her skin, lightens blemishes, evens out her skin tone. Alas, acne still forms. It's hormones. I used it a few times on my forehead and I'm surprised at how it smooths out the texture. I have an oily T-zone and I'm really surprised by the results.

I love it! Azelaic acid has been saving my oily, acne-prone skin for years. The zinc content definitely helps too. And this serum is the best of them all. Better than the Anua green serum. It's light, non-greasy, and absorbs quickly. I'll definitely keep buying.

I was hesitant at first to use this product, but it exceeded my expectations. The serum evens out my skin tone, makes acne scars less noticeable, and removes dullness. I am very satisfied!

A very light liquid serum. I like it because it really reduced the redness of my PIE (post inflammatory erythema). Great!

Tir Tir azelaic acid serum suits my skin perfectly. I have combination skin with small blemishes. I have been using the serum for two weeks now and I notice that my skin is more even. The texture is light and transparent. It feels a little sticky at first, but it absorbs quickly and the sticky feeling disappears. This is the best azelaic acid product I have tried so far.

I have sensitive skin with rosacea and it works very well. I apply it as the first step in my morning routine and it absorbs quickly, leaving my skin feeling great. It's fragrance-free and works very well.

Considering the high percentage of azelaic acid it contains, it has a very light and runny texture. It leaves a slightly sticky feeling on the skin, but once it's absorbed, it's no longer bothersome.

This is my first azelaic acid and I am very satisfied. I really have no complaints about this product. Telstura is very nice, watery, gentle, not too thick or greasy, and spreads nicely, and after application it leaves a very nice skin surface, completely matte. It does not irritate the skin at all. What is most important to me, in the morning after cleansing I put it on my entire face, then spf and cream, and after that I can immediately put on makeup without any problems. It does not peel at all under makeup, nor does it interfere with makeup in any way, so I am delighted with how well it works in the morning under makeup. And it has no smell. The bottle is nice and glass.

great serum for skin with rosacea, after a few days the skin is in much better condition, less redness, improved skin texture, soft, I am pleasantly surprised

Pleasant serum, non-sticky, neutral scent. Visibly improves skin condition
