moisturizing is very important for any girl to keep skin soft and pliant. There are several good products out there but it's a matter of personal preference and finding what works best for your skin type. Unless you're talking about the really expensive creams or have a lot of skin/sun damage, you can get something that works well enough for around $20-$30. I've heard Olay products are good but I don't use them personally. I prefer Neutrogena for everyday cleansers and moisturizers.
Great advances have been made in recent years in anti-aging, anti-wrinkle creams and they have gotten more accessible, especially if you want to spend a lot of money. The best trick imo is to be consistent and use them regularly over a period of time if you want to see actual results.
but as Flan said, nothing is really going to feminize your face other than perhaps a steady dose of estrogen
