Sarah :
Most moisturizer contain niacinamide so you don’t need a separate product for that

My routine: Niacinamide 10% and Tret 0.025% at night | Vitamin C and Azelaic 20% in the morning. No irritation, just introduce it slowly while using less products. 💗

Can you use all of this together? And in that case; which order? I would think: Niacinamide, peptides, azeleic acid and then tretinoin last before moisturizer. Am I crazy?!?!

Just received my Tret order from Amazon pharmacy. Excited to start using & wish I would have a long time ago. I love my Ghk-cu serum and green tea combo, noticeable changes applying that with RLT. Also derma stamping once a month.

ok this is genuinely good skincare advice, all three pairings check out! niacinamide really does help with oil, inflammation and the skin barrier (which offsets tretinoin's dryness), and azelaic acid is a great two-birds pick, it treats acne and fades dark spots by blocking the pigment enzyme. and he's right they're all fine together, splitting azelaic AM / tretinoin PM is a smart way to cut irritation. one small "manage expectations": peptides are the weakest-evidenced of the three, they're a fine gentle add but it's the tretinoin doing most of the collagen heavy lifting, so "peptides make wrinkles go bye-bye" oversells them a touch. and as always, daily sunscreen is the real multiplier (tretinoin makes skin sun-sensitive). solid video though!

Shall I assume that all these can also be used with retinoids like Differin?
