Tear the sachet and simply consume the collagen powder. For a maximum effect, consume this collagen during an empty stomach, especially in the morning and before bedtime for the first first month. For the consequent months,you can take just one sachet per day, or as needed.
This collagen can also be used as a mask. Dilute a small amount of this collagen powder with water and apply directly to the face. Leave for 30 minutes and rinse thoroughly.
