Is It Bad to Use Moisturizer with Sunscreen at Bedtime?

One habit that I have seen many people get into is using the same moisturizer both morning and night. They’re trying to keep their life simple by just using one product, and I certainly can respect this. Most people who make a conscious effort to care for their skin (enough to use moisturizer both morning and night) usually know that a moisturizer with sunscreen should always be worn during the day.

But what if they are then using that same SPF moisturizer at night? Is it harmful to your skin?

If you are someone who absolutely will only use one moisturizer both day and night, it is better to have one with a sunscreen, since sunscreen is the best way to prevent premature wrinkles.

However, sunscreen worn at night is not ideal for your skin for three reasons.

1. At night your skin is in repair mode, and needs a moisturizer with repair ingredients. While you sleep, your skin is at rest and is not being exposed to the environmental stressors that age the skin. I truly believe that by washing your skin at night and performing a nighttime specific routine, you can really help repair your skin and help to control how quickly your skin ages.

2. Sunscreens may potentially be clogging your pores. Certain sunscreen ingredients may cause this for skin types prone to congestion. So certainly using it at night when your skin doesn’t need it is never a good idea.

This is why, for those with acne-prone skin it’s important to use sun protection containing Zinc Oxide like Renée Rouleau Daily Protection SPF 30, which will not cause this to happen.

3. Your skin doesn’t benefit from using the same product all the time, year-round. While I don’t believe your skin gets used to products and stop working, I do believe it is helpful to give your skin a change by switching to different products, depending on the season, certainly, but even morning and night. Your skin benefits from exposing it to different performance ingredients. At night it’s very beneficial to use a skin serum underneath your moisturizer to increase the desired result.

I personally like to change up 2-3 products in my skin care routine every change of season, primarily because my skin has different needs, but also to give my skin a bit of everything. This is a well-rounded approach that I find beneficial and I advise my clients to do the same.

Bottom line: It’s generally not harmful to use a moisturizer with SPF at night, it’s just not the best strategy for your skin if you want it to look and feel its best.
