I started using Skin + Me daily doser in January to help my cystic-acne prone 44yr old skin, which was super greasy (though realised thanks to Mumsnet the greasiness was due to taking high strength biotin supplements !).
Because it has tretinoin in it, I need to wear SPF50 daily. Because of my acne and scarring and generally awful skin, I need to wear foundation most days.
So I in the morning I wash with CereVe face wash in the shower > apply The Ordinary Azelaic acid > moisturiser (I like Estee Lauder's DayWear) > SPF > foundation. Only use primer if I'm going dancing or something.
Have literally just had this Beauty of Joseon SPF50 delivered after reading all the hype on Mumsnet about it:

Was using La Roche Pose Anthelios, but it's from last spring/summer and know it goes off after 12 months so don't want to risk it not working and getting sun damage.
I know what you mean about allll the steps OP! I have dabbled with ditching the moisturiser step some days, and seemed ok tbh. Will see how this new one is later today!
At night I cleanse thoroughly, use daily doser (containing tret amongst other acids), wait 10 mins, apply serum (Aveeno one), night moisturiser (Clinique Moisture Surge Overnight Mask).
I have terrible genes and terrible skin but doing this the past three months, plus eating more cleanly and hydrating properly, has really helped. Plus I like doing it!
