Hello, the team is concerned that
Encapsulated Retinol will have compatibility issues with
Aloe Vera Gel (Lite) I can't verify. But expect compatibility issues. when mixed together Will cause disintegration of the gel because
Encapsulated Retinol seems to be negatively charged, but
Aloe Vera Gel (Lite) is positively charged if this formula is changed from
Aloe Vera Gel (Lite) to
Aloe Vera Gel (Heavy) No problem. for the age of the formula If it is spoiled (the formation of germs), it will last at least 2 years if the mixing process is clean.
