Vitamin C is the darling of the skincare world, we all agree on that. It's your go-to for glowing, youthful skin! Whether you’re diving into Vitamin C products for oily skin or starting to use Vitamin C serum for even-toned skin, getting it right is key. But before you slather on this skincare star, let’s run through the must-know do's and don'ts that are backed by science.

Do’s of Using Vitamin C Products:

1. Always Use Vitamin C with Sunscreen
According to dermatologists, combining Vitamin C with SPF boosts your skin’s protection against UV rays and pollution (source: The Journal of Clinical and Aesthetic Dermatology). Apply your Vitamin C serum in the morning and follow it up with a good sunscreen. It's the ultimate tag team for glowing, protected skin!

2. Pick the Right Concentration
When starting with Vitamin C skincare products, especially a serum, it's best to stick with lower concentrations (around 10%). Studies (source: The Dermatology Research and Practice Journal) show that higher concentrations (above 20%) can irritate your skin, especially if you're just starting out. Gradually build up your tolerance.

Deyga’s latest launch Vitamin C Foaming Face Wash has a mild proportion of Vitamin C which is good to start with even for sensitive skin types. It’s just a face wash but it actively works on reducing pigmentation giving you a radiant even-toned complexion.

3. Store Your Vitamin C Properly
Keep your Vitamin C products in a cool, dark place, preferably airtight. This keeps them fresh and potent for longer. Vitamin C skincare products are sensitive to air and light, so no leaving that bottle or tub on your bathroom counter! Research (source: National Center for Biotechnology Information) shows that Vitamin C can degrade quickly when exposed to light.

Don’ts of Using Vitamin C Products:

1. Don’t Mix with Retinol or AHA/BHA Acids
As tempting as it is to pile on every skincare hero, Vitamin C doesn't play well with everything. Retinol, AHAs like Glycolic acid, and BHAs like Salicylic acid can cause irritation when combined with Vitamin C, especially for those using Vitamin C products for oily skin (source: The International Journal of Dermatology). Stick to alternating days for these ingredients to avoid breakouts or redness.

2. Avoid Using Expired Products
Vitamin C oxidises over time, meaning that yellow or brown-tinted products have gone bad. Oxidised Vitamin C isn’t just ineffective; it can even harm your skin by promoting free radical damage (source: The Journal of Clinical Investigation). So, keep an eye on that expiration date and always buy fresh Vitamin C skincare products.

3. Don’t Apply Vitamin C on Damp Skin
Vitamin C works best when applied to a dry face. Applying it on damp skin can increase the risk of irritation and reduce the efficacy of the product (source: British Journal of Dermatology). Let your skin dry completely before applying that serum!

4. Don’t Skip Hydration
Vitamin C can be drying for some skin types. Always pair your Vitamin C with a good moisturiser to keep your skin barrier intact (source: British Journal of Dermatology). A hydrating serum or moisturiser post-Vitamin C is a must!
