Quick Take - Daily vs. Alternate-Day Application

• The most commonly asked question is, “Can I use vitamin C serum every day?” Most dermatologists agree that daily use is safe. Especially if you are using a vitamin C serum with a 10-15% concentration, it is perfectly recommended for all skin types.
• Use daily if you want to target pigmentation and have oily, normal or combination skin type.
• Use on alternate days if your skin is sensitive and tends to react. Alternative usage is also recommended if you use retinoids or exfoliants.
• Pro Tip: Start slow with a twice or thrice-a-week application. Increase over the course of the next 2 weeks.

How Vitamin C Works on Skin

So, what is the big deal about Vitamin C serum? Let’s decode the hype around it. 

• Antioxidant Action: Vitamin C is known to neutralise free radicals, protecting your skin from environmental stressors like sun damage and pollution.
• Collagen Boost: It boosts collagen production that supports firmness as our skin starts to age.
• Brightening of dark spots: Tackles dullness, pigmentation, and uneven skin tone. It targets concerns like dullness and hyperpigmentation, and consistent use significantly reduces dark spots and blemishes. Your skin starts appearing healthier and brighter.

Factors That Decide Your Ideal Frequency

Skin Type & Sensitivity

Everyday use of vitamin C can lead to irritation if you have dry or eczema-prone skin type. People with sensitive skin should use it thrice a week and slowly increase frequency with time.

Concentration & Formula

• If you are starting, begin with 10% Ethyl ascorbic acid.
• If your skin is used to it, you can go for 15-20% concentration.
• Use gentler derivatives like sodium ascorbyl phosphate.

pH & Active Ingredients

A pH level of 3-4 is ideal for vitamin C. Don’t mix them with strong actives like retinol or glycolic acid. These are low-pH exfoliants, and it's best to space them out.

Climate & Lifestyle

Daily use of vitamin C serum offers antioxidant protection, but skipping SPF is not an option!

Daily Application - Step-by-Step AM Routine

There is a correct way of applying vitamin C serum every morning:

1. Cleanser – Start by prepping your skin with a gentle cleanser to wash off all the dirt and oil.
2. Pat Dry – Your skin is now ready to absorb the products better.
3. Take a few drops into your palm and apply them all over your face. Try the CITTA Vitamin C Brightening Face Serum.
4. Wait time – Give it a few minutes before applying the next step for better absorption.
5. Moisturiser – Seal in everything with a hydrating moisturiser.
6. Broad-Spectrum Sunscreen (SPF 30+) – Finish your routine with a high-SPF sunscreen.

When You Shouldn’t Use It Every Day

• If you feel a stinging sensation or notice flakes after applying the product, try to reduce the usage to alternative days.
• Don’t mix with other strong actives like retinol, AHA/BHA or after chemical peels or laser treatments.
• Always use under a dermatologist's opinion. Patch testing is a must!

Derm-Backed Tips to Minimise Irritation

• Patch test behind your ear, neck or jawline.
• Start slow: Start with using 3-4 times a week. 
• Pair with hyaluronic acid or niacinamide to get the most benefits and rule out dryness. 
• Use it in your night routine if morning usage feels too harsh.
