UPDATED: What's the Difference bet Crest 3D Whitestrips : eBay Guides

This is my first guide and the purpose is to shed some light on the range of products in the Crest Whitestrips range so you can make a more informed decision should you decide to purchase.

I will touch on 5 products commonly seen on eBay.
The main difference between these would be the strength of the strips and the duration of treatment. Strength refers to the percentage of hydrogen peroxide - the active ingredient used to brighten your teeth.

This is exactly the same ingredient used by dentist in professional whitening treatments.

CLASSIC:::

• The first product in the range (hence the classic name), this has the weakest strength of 6% Hydrogen Peroxide
  
• The classic is packaged in a box with 56 strips, 28 for the upper set of teeth and 28 for the lower set of teeth. Treatment spans 2 weeks, with 30 minutes twice a day to get maximum effect.

PREMIUM:::

• Crest Whitestrips Premium has significantly more whitening strength than the classic.
  
• At 10% hydrogen peroxide, it works well for many people, especially people with yellow teeth.
  
• The premiums are packaged in a container with 28 strips, 14 for upper and 14 for lower
  
• Treatment spans 7 days, two 30 minute sessions a day. Results can be seen in just 3 days

PRO EFFECTS (Previously Known as PREMIUM PLUS):::

• Crest Whitestrips Premium Plus has the same strength as the premiums. However the treatment contains more strips than the premiums
  
• Treatment contains 10 day supply of 40 strips, 20 for upper and 20 for lower.
  
• Based on number of strips, the premium plus is an attractive buy.
  

RENEWAL:::

• Crest Whitestrips Renewal is marketed to the older generation customers above 50+.
• These strips are slightly weaker than the premiums / plus as they contain 9.5% hydrogen peroxide gel.
• Treatment consists of 40 strips, 20 for the upper and 20 for the lower teeth.

DAILY MULTICARE:::

• Currently the newest member of the Crest Whitestrips range, Daily Multicare has an unknown strength as of now but is set in between the Classic and the Premiums
• Treatment contains 84 strips, 42 for the upper and 42 for the lower teeth.
• Each application take only 5 minutes and the advantage is that you have better control over the effect especially if you may experience sensitivity.
