Though am not an expert in this, I have taken enough trainings on skin care. I belive that would help you in getting some info. I want to answer the second question first.

See if yu see yr eyes got sunken inside the best solution is that to take proper food. Means to have enough protein content. C Vitamin can only help for good sight, not very much for your case. I strongly suggest Protein Powder from Nutrilite for this complaint.

And for the first question… the best solution is to use Artistry branded products. Check the source if you have or I can give you if you want. You have good stuff there to prevent wrinkles. I have some good guidelines for massaging…

1. Apply little amount of cleanser on wet face and start massaging. while you massage, do it outwards on forehead and chin. circularly backwards on your cheeks and downwards on your nose. and upwards on your neck. then clean your face. this would help you clean the skin pores and removes all the oil and durt.
2. Then have toner on a cotton and wash off the remaining oils or durt on your face. let your skin dry for about ten seconds.
3. Then apply little bit of moisturiser on your face and apply the same as i said for cleanser. Artistry has SPF15 formula and i strongly suggest that brand.

If you want to have more tight skin, I suggest Alpha Hydroxy Serum Plus and Creamy Massage applied. You can feel the difference in just 2 weeks. I guarantee that.

If you still need anymore clarification, you can contact me. I can also help you reach some skin care experts too. You can have free consultation. And for anything else, you can always reach on my mobile +91 – 9885 33 99 63 or my mail id, subhash_bk at yahoo.com

Just try squeezing the the eyes tightly shut and hold this for about 5 slow seconds and then release. Repeat this 20 times.

This helps build the muscle around the eyes and thickens up the area.

"Step 1:
Massage techniques
Use a few drops of essential oils and warm between your fingertips. Apply with stroking movements underneath your eyes. Lift the skin with sweeping movements, and start upwards to work against gravity. A relaxing technique is to sweep your fingers across your forehead.
Step 2:
Eyes
Pinching your eyebrows will relieve tension and reduce puffiness and congestion. Use your ring fingers to press the area beneath the eyes. Breathe out every time you press down.
Step 3:
Jaw
Use your thumbs and index fingers to pinch the jaw line with a suction motion. Work from the centre to the edge of your face. Pinching the jaw line will get blood and nutrients to that area of the face. Finish by stroking the forehead and the whole of the face."
