What does vitamin C really do?

We all know that oil and water don't mix, but did you know that combining vitamin C with retinol can spell disaster?
The benefits of vitamin C don't just stop at the body but at the whole body. The perfect compromise to prepare your bikini body in complete peace of mind.

Looking for the perfect beauty routine? Depending on your skin type, it can actually be difficult to determine which products combine best and give you the best results. You might also go through some trial and error during your quest. To avoid this, L'OFFICIEL guides you through your new skincare routine with a list of ingredients that you should never mix together.

Vitamin C and AHA & BHA

AHAs and BHAs, such as glycolic, salicylic, and lactic acids should never be used with vitamin C. Vitamin C is also acid and is unstable, so the pH balance will be disturbed by the layering of these ingredients.

Vitamin C and Niacinamide

Niacinamide is found with vitamin C in some multi-ingredient serums as antioxidants, but it's never a good idea to mix them together. Both ingredients are useful for improving acne, but used together can trigger breakouts. Also, their useful properties may be diminished. If you must use them together, apply them at least 10 minutes apart.
AHA & BHA and Retinol

• 
  
•  For long and silky hair
• 
  
• Vitamin C stimulates the hair follicle and promotes hair growth, prevents dry ends, and helps regulate sebum.
•  Strong and healthy nails
• 
  
• Daily consumption of this vitamin helps strengthen the nails from the inside, their growth, and their toughness to keep them healthy.
• 
  
• 
  
•  Reduce the signs of aging
• 
  
• With its high content of antioxidants, vitamin C fights the factors responsible for aging and helps rebuild skin tissues in their depth while eliminating wrinkles and other signs of aging.

Niacinamide and AHA & BHA

Niacinamide used with AHAs and BHAs has no effect and may even cause redness. Because niacinamide has a pH of around 5-7, it can raise the lower pH of acids, which is around 3-4, and negate its properties. Used separately, both ingredients can improve skin texture, acne, and signs of aging, so we encourage you to continue using them (but not in direct combination).

Glycolic acid and salicylic acid

These two ingredients are probably never to be used together as they both slough off dead skin cells. Combining them could cause a lot of irritation and ruin your skin barrier. Use one and follow with a moisturizer.

Sunscreen should be worn every day but should never be mixed with makeup. When wearing both, apply sunscreen separately from makeup and wait before applying other products so they have absorbed well.
