Hey!
I'm a 32-year-old male. I started to use SPF three years ago, however, I sustain a lot of hyperpigmentation (around the eyes, similar to melasma) and broken capillaries from my younger, unprotected years. Some skin laxity can be appreciated around the lower part of the jaw, most likely due to weight loss or weight fluctuation. The 'T' areas of my face suffer from extreme oiliness, and open comedones (blackheads, especially on and around the nose). My skin is pale with a tendency for freckling and burns (Fitzpatrick type II). However, my skin appears to be quite resilient with retinoids and vitamin C.
I'm delighted with the results I'm seeing with this routine, which I have followed for the last two months. At the age of 32 with my lifestyle characteristics (high-stress job environment, tobacco vaping) some aging signs are evident for the last couple of years; this routine certainly helped reverse several dimensions of the observed aging signs. However, I still can't seem to mattify or eliminate the open comedones on my nose, despite my best efforts...
It's great that you are already getting good results from this routine, thank you very much for sharing it and adding the details! You should keep seeing improvements from it: you are using some of the most potent actives out there, and it takes consistency & time for them to work properly.
Since you are tolerating everything well, I really won't change almost anything. You could consider switching your Caffeine solution serum to a niacinamide (around 4%-10% - more proven to have an effect in suppressing hyperpigmentation compared to EGCG, and also helps control oiliness). It can be used all over the face including under eyes. Tranaxamic acid product includes around 2% niacinamide though, and this is a good starting concentration, so it's just a consideration.
