When to use Medicube PDRN Pink Peptide Serum

How do you use Medicube PDRN Pink Peptide Serum?

1. 1Wash your face with a gentle cleanser and gently pat dry.
2. 2Apply the serum evenly over your face and neck. Medicube's layering directions start with 2 to 3 drops; gently pat for absorption.
3. 3Follow with your regular moisturizer.
4. 4During the day, apply sunscreen last. Apply makeup afterwards if you wear it.

The US product comes in Salmon DNA PDRN and Rose PDRN versions, with the same morning and evening directions. Medicube allows another 1 to 2 applications for extra hydration, but extra layers are optional.1

Can you use it with vitamin C or retinol?

Medicube allows the serum alongside vitamin C or retinol. Introduce unfamiliar active ingredients gradually and adjust use to your skin's tolerance. General routine guidance places retinol at night and favors one serum at a time, rather than stacking several new formulas together.13

If you use a skin medication, general guidance puts medication immediately after cleansing, before moisturizer or sunscreen. Keep that treatment step distinct from adding a cosmetic serum. Ask your dermatologist about the order if your prescribed routine leaves you unsure where the serum belongs.2

A useful routine does not need every available product category, even if the bathroom shelf has room for an entire supporting cast. Cleanser, moisturizer and sunscreen cover the morning basics; adding a serum is a choice, not a missing requirement.3

Who should be careful?

Medicube positions the serum for dry, dull skin and loss of firmness, while also allowing use on oily skin. Both full ingredient lists include fragrance. If fragrance tends to bother your skin, factor that into your decision rather than relying on the low irritation description.1

Test a new product before adding it to your routine, and minimize how many new products you introduce together. More products increase the chance of side effects and irritation. If you develop skin irritation or contact dermatitis, an inflamed skin reaction, stop using the product and make an appointment with a dermatologist.3

When should you use peptide serum?

Use a peptide serum when you want an optional addition to cleansing, moisturizing and sun protection. Peptides are strings of amino acids, the building blocks of proteins. Some research suggests they can help reduce inflammation associated with visible skin aging, but the complete formula matters more than the presence of peptides alone.4

Peptides can be part of a useful formula, but their name on the bottle is not a job reference for everything inside. For this Medicube serum, choose it primarily for extra hydration and a softer, plumper feel rather than expecting an immediate change in firmness.14
