I completely understand what you say, OP, the first few signs of visibly ageing can be a bit of a shock to the system. But there are things, practical and mental, that you can do to improve things to the point you no longer consider yourself "ugly" (which is such an ugly term - we wouldn't speak to strangers the way we speak to ourselves sometimes).
For your skin and hair, nutrition is key. Leafy greens, nuts and seeds are usually your best bet, and for your skin, also animal fat and collagen, which you can get from homemade broth by boiling animal bones (or just by eating cartillage, but some people are funny about its texture).
Keep your skincare simple and don't use lots of complicated products. I use the blue Nivea once a day, after showering, and it makes an amazing difference long-term. Light make-up, not the tonnes of chemicals people often smear on their faces in Youtube tutorials now. And a face mask once every 2-3 weeks, depending on where you are in your cycle, that can be cleansing or hydrating. Play around with those a bit and see what feels best. And many people don't want to hear it, but for older skin, a layer of fat underneath helps to keep it looking younger. So consider putting on a small amount of weight, just to plump it up a bit.
No alcohol. Whenever I don't drink, my skin and hair look a thousand times better.
Your hair will also need different products; it sounds like it's lacking moisture and here, it is useful to spend some money. What products to recommend would be best discussed with a hairdresser; my hair is curly, so I use products which seal in high amounts of moisture, and condition daily with a commercial leave-in hair mask once a week and an olive oil one once every 2-3 months.
Your teeth need looking at by a dentist - just to test their density. But things you can do otherwise is use an enamel-protecting toothpaste and a good look at your diet - if it's high in carbonated drinks or fruit, that will wear your teeth down considerably over time. Eat calcium-rich foods like cheeses, milk and unsweetened yoghurts to help keep your teeth strong.
As for the rest, protect yourself from the sun - long sleeves, covered chest and back, a wide-brimmed hat and seek the shade where you can. Go shopping if you can, to find a style that suits your shape, and buy only variations of that style. Find some great shoes, jewellery and sunglasses - it's amazing what a difference in confidence a few accessories can make.
And if all else fails, remember that the crone is the most highly respected of the three stages of womanhood; she is wise, confident in herself and her place in the world, so own the crone when you meet her.
