Moreover, mounting evidence has demonstrated the feasibility of several types of CPPs, including TAT-PTD, TCTP-PTD, polyarginine, and penetratin and analogs thereof (Table 1), in the transepithelial delivery through nasal and intestinal epithelium (Zhu et al., 2014
There are oral tablets or capsules, sublingual applications (under the tongue), intramuscular injections, and skin patches, among others
Frequency: Usually given intramuscularly, ranging from daily to weekly injections
"Be it the antioxidant activity, synthesis of collagen and elastin, production of energy in the cells, or the melanin formation." Now, let's settle the copper peptides When we deal with the copper peptides, we mainly look at the signaling peptides (stimulate the synthesis of collagen and elastin) and the carrier peptides (deliver trace elements to the skin)
It is strategy
