You’re going to hate this but...
Face washes can be very drying. And a face brush can be a bit harsh if you mean one with bristles (especially a motorized one). Used together especially, they’re probably not great for the integrity of your skin and it’s barrier function. The salicylic product will exacerbate this. Salicylic acid is great, but on top of all that physical exfoliation and used everyday it overkill.
This means your skin will struggle to retain moisture and stay hydrated. You mention skin looking lackluster and lines looking more prominent. Those are key signs your skin is struggling to stay hydrated- hydration is what makes it look glows, plump, full, vibrant.
You’re using a Matrixyl and Hyularonic Acid serum, which should promote the barrier function and add hydration, but if you keep scrubbing off and washing away the top layer of your skin, you’re really working against yourself.
So, really, seriously, I’d consider making your cleansing routine a bit gentler. And using the salicylic product every other day.
The other thing would be have a think about whether you’re applying enough of the Face Finishing Tint to get a proper spf 30 effect. That would be about one third to one half a teaspoon per application (face and neck). So a 59ml jar of that product would last you 24-36 days. You really need the sun protection as you’re using a retinol daily.
Advice has recently changed- it used to be said that there was little effective difference between spf 30 and spf 50 products. However, as people don’t tend to use enough product to achieve the advertised spf, it’s better to use a higher spf, as then you’re still not getting the advertised spf, but you are getting more like an adequate level. As you’re using a retinol daily, it’s vital you get adequate sun protection.
