Human Growth Hormone

i know its pretty young but I just want to be cautious although Im wondering is it advisable for girls like me (just 21) to use anti aging creams like olay and ponds as nightly cream or should i just stick to regular moisturizers?

You are never too young to start! I wish I’d started earlier, although I’ve had good results so far with starting in my late 20’s. You should do what you can to preserve your skin, and the most important thing is to wear sunblock every day, even in winter, when it’s overcast, etc.. etc… My dermatologist(s) have hammered this into my head for years. There are a ton out there in cosmetic lines that are very good, but very expensive. I used "Elta Gold UV Shield" for a while, which was sold at my derm’s office, but was $25 for a 3 oz. tube, but then found a good non-greasy sunblock that was much less expensive and sold in most drug stores that my derm approved: Neutrogena’s Ultra Sheer dry touch sunblock. I use spf 45, but I think they make it in 30, 70, etc… It is not like other sunblocks or lotions, it absorbs right in, moisturizes, and is so light you can’t feel it on your skin…it can be worn by itself, or under foundation or powder. I would also recommend Cetaphil cleanser (also discovered through visits to dermatologists) or the generic brand of it that they sell at Long’s (half the price, same ingredients)…it is not soap, so it moisturizes, but doesn’t block pores (I had very bad adult acne and this is what every derm has recommended to me over 20 years). You might also look into micro-dermabrasion…sounds awful, but it’s really just like getting a facial, and it’s really good for rejuvenating the skin, and stimulating collagen to the surface of the skin which helps it look younger. I did this professionally for a while to minimize old scars I had from acne (and it worked very well), but people do it just to keep their skin nice. It costs about $125 and up, if done at a spa or derm’s office, but there are also over the counter options available. I have used the Spa Sciences micro dermabrasion kit (about $40, with a supply of the cleansers, lotions, etc… that still hasn’t run out a year later, doing it once a month) with great results, but you need to be very gentle until you find out what your skin can tolerate…it doesn’t seem like it’s doing much during the process, but it really does! and you can see the results right away (within a few hours, but your skin feels great right afterward). Any other facial product by Spa Sciences is also good…I have tried a bunch, and ran it by my derm, who liked the products also…you can find them on the web or in Longs, Rite Aid, Target, etc… Their eye wrinkle lotions and masks are wonderful, and if you are worried about aging, you should use some sort of eye area moisturizer daily. For the rest of your body…at your age, I’d recommend baby lotion, or one of the Cetaphil lotions (or a generic version of it), as these are very good for skin and relatively "pure" compared to other lotions (as well as economical)..Neutrogena is also very good stuff. And, my goodness, girl!! Don’t worry about aging…it only gets better!

I am 27 years old, I have dry skin and dark circles under my eyes…
I already started to have lines on my forehead
when should I start to use anti aging cream and which ones should I buy?

You can start using them once you see wrinkles starting to show on your face. It helps to use them before it gets worse. It would be better if you can buy natural skin care products that works well for anti aging without all those harsh chemicals…
