3. Moisturizers with collagen
The collagen molecule is not small enough to be absorbed. It is an active ingredient and, in order to make your skin look younger, it is supposed to penetrate. WHICH NEVER HAPPENS! You simply pay more for a moisturizing product that can be bought for less money.
4. At-home medical peels
Medical peels are manufactured for professional use and only when they are really needed should you apply them onto your skin. These products have too many strong chemicals and can damage your skin if you use them at home. Harsh peeling methods lead to discoloration, scarring, allergy and redness.
