I'm checking in OP as I'm most definitely guilty of piling items.
I am a bit embarrassed to even take a photo of my stock cupboard, it's years in the making.
My problem is that I just cannot resist a good offer, it started some years back with an online shop that had the pricing incorrect, so I bought multiple items of shampoo, face washes etc. Intending to give out as stocking fillers as it was close to Christmas. But I didn't and thought that it was a great idea to keep as it will eventually get used. And it spiraled from there. I have so much reduced to clear items, that I paid silly prices for, for what is usually quite pricy items. I do have a teen dd so a lot was intended for her, but she had super sensitive skin and it didn't work for her. So earlier this year I had a massive sort out, and decided I would not be buying any more beauty items. But, where I live, we have beauty warehouse sales and I could not help myself to not pop in, just 'to see' what they had. Sigh, waked out with a huge bag, so had to rearrange my cupboard again. But included in that was a good supply of uvp50 so that is always a must. But, these things all gave best before dates and some are really out of date. But how harmful can an out of date moisturizer be, or soap or face wash really. Sun protective I don't use best before as I take that seriously having had skin cancer surgery. It things like I bought extra Mitchum roll on, but I just prefer the other version. So it's just sitting these, but I have started making a dent now.
You asked earlier if people who have too much skin products, hoard other items too. Yes, I am guilty of that, so I think perhaps I may fall into the hoarder category. I get quite anxious if I don't have back up coffee or washing detergent in the cupboard. So when I see a good deal (like I did this week for BF) then I buy bulk. Now I am feeling fine as I get stressed if I think that I may just have to pay full price for things that are generally pricy day to day (esp now).
But I am aware of it, and have stopped buying even if it's an offer that is hard to resist as let's be honest, I am not gifting that stuff out.
I am glad I am not alone though. 😊
