I think the term "anti-ageing" is really very misleading. In my opinion you can use products that are age-preventative, ie. products that are high in anti-oxidants and products that will help your skin to maintain a high level of hydration (such as HA serums), then there are products that are indicated for "age correction", ie. if you see a probem on your skin, use the appropriate product to try and fix it. So if your eyes are starting to bother you and you are noticing changes such as fine lines forming, then yes, it is a good time to start looking at eye products.
If you see that your skin is becoming lax or it’s losing its healthy glow, then yes, start using a growth factor serum and serums high in retinol to start boosting and waking up that skin to function better again. So my advice is going to be that you have a consult with a good aesthetic doctor who can help you understand your skin and figure out where your biggest problems are, and help you acordingly with products and treatment prescriptions. You are welcome to come and see me or one of our Skin Renewal doctors at your nearest Skin Renewal Branch.
