Vitamin A and collagen peptide: keep them apart

Keep them apart

Use them at different times of day with peptides in the morning and vitamin A at night to prevent skin irritation. Vitamin A and collagen peptides both try to boost skin renewal at the same time, which can easily cause redness and sensitivity. You can easily fix this by using a gentler formula or spacing out when you apply them.

Questions and answers

Can you use vitamin A and collagen peptide together?

Keep vitamin A and collagen peptide apart in the same routine, as combined stimulation may increase irritation. You can alternate usage by applying a retinoid in the evening and peptides in the morning.

Which goes first, vitamin A or collagen peptide?

Keep vitamin A and collagen peptide apart by alternating their usage, such as applying your retinoid in the evening and peptides in the morning. This helps prevent irritation since combining them in the same routine may overstimulate the skin.

Are vitamin A and collagen peptide good for sensitive skin?

Keep vitamin A and strong retinoids apart from collagen peptide in your routine because combined stimulation may increase irritation, though you can alternate usage by applying a retinoid in the evening and collagen peptide in the morning. No7 Protect & Perfect Intense Advanced Night Cream contains both ingredients.
