Vitamin C: radiance and antioxidant protection

Why include vitamin C in your skincare routine?

Vitamin C is one of the star ingredients in anti-aging skincare and professional cosmetics. This powerful antioxidant helps protect the skin against free radicals caused by pollution, oxidative stress, and UV exposure.

Its main benefits:

  • Brightens and revives a dull complexion
  • Helps reduce the appearance of age spots
  • Stimulates the natural production of collagen
  • Improves skin firmness and texture
  • Protects against environmental damage

It is particularly suitable for tired skin, uneven complexions and for people who wish to prevent the signs of skin aging.

When and how to apply it?

For optimal effectiveness, apply your vitamin C serum. In the morning , after cleansing and before your moisturizer. On clean, dry skin, a few drops are enough.

Why in the morning? Because it acts as an antioxidant shield throughout the day, especially when combined with sun protection.

Infinima Tips:

  • Opt for a light texture for better absorption.
  • Store your serum away from light to preserve its stability.
  • Always combine vitamin C with sunscreen to maximize its anti-aging effect.

Hyaluronic acid: intense hydration and skin rebound

Why use hyaluronic acid?

Hyaluronic acid is a molecule naturally present in the skin capable of retaining up to 1000 times its weight in water. It plays a key role in skin hydration, elasticity, and volume.

Its advantages:

  • Deeply hydrates without weighing down the skin
  • Plumps up dehydration lines
  • Improves skin elasticity and comfort
  • Suitable for all skin types, even sensitive

It is an essential active ingredient for maintaining a healthy skin barrier, particularly during winter or in dry environments.

When and how to apply it?

Hyaluronic acid can be used morning and evening . Apply it after your active serums, ideally on slightly damp skin to promote water retention.

Don't forget to seal in the moisture with a cream suited to your skin type.

Infinima Tips:

  • Opt for a formula containing different molecular weights for multi-level hydration.
  • Combine it with ceramides or peptides to strengthen the skin barrier.

Niacinamide: the balancing active ingredient for even skin tone

Why incorporate niacinamide into your routine?

Niacinamide, also known as vitamin B3, is a multifunctional ingredient particularly valued in professional skincare for its soothing and regulating properties.

Its main benefits:

  • Reduces the appearance of enlarged pores
  • Regulates sebum production
  • Reduces redness and inflammation
  • Improves skin tone evenness
  • Strengthens the skin barrier

It is ideal for combination, oily, sensitive or blemish-prone skin.

When and how to apply it?

Apply it after hyaluronic acid and before your moisturizer or night cream.

Infinima Tips:

  • Start with a moderate concentration if your skin is reactive.
  • If your skin is very sensitive, use niacinamide in the evening and vitamin C in the morning to limit the risk of irritation.
