Hi all, what product types fit well with use of Niacinamide please?

Niacinamide friends

Would anyone have any product recommendations to address a tech neck? This is where the neck develops horizontal wrinkles from bad posture/tech use/reading/ any continuous movement that involves looking downwards.

I was kindly sent SKIN1004's Madagascar Centella Tone Brightening Capsule Ampoule to try recently so have been using it for about a month now. This is a concentrated version of a serum and you get tons of product sure to last ages (100ml).
This is suitable for all skin types but oily skin may prefer to use less of this as it is so extremely hydrating. It is Vegan, cruelty free, fragance and alcohol free and contains vitamin c derivative, niacinamide, tranexamic acid, and niacinamide so essentially this is your all in one ampoule for brightening and reducing marks/pigmentation. I've noticed it reduces redness, is very hydrating, a gel like consistency that absorbs semi well, no stickiness residue left behind and does subtly brighten the skin. I need to use it a bit longer to assess fading of marks as it's a bit too early to comment on that but all in all, it has been a welcomed addition to the AM skincare routine and I haven't had any breakouts either. 💕 Thank you to @skin1004official @go.picky for sending this out to try.
