When acne meets age-related changes

Many people are familiar with this situation: years of struggling with oily skin, enlarged pores, and inflammation, only to be followed by signs of aging—age spots, first wrinkles, and a feeling of tightness. Most cosmetics address one issue: either acne or age-related changes. But what to do when both problems are present simultaneously?

Jan Marini Age Intervention Duality Cream is a comprehensive treatment that combines anti-acne and anti-aging benefits in a single product. This product is specifically designed for those who struggle with age-related acne and want to avoid having dozens of jars on their shelves.

When acne meets age-related changes

Two components - one solution

The uniqueness of Age Intervention Duality lies in its two-component system. The product consists of two containers with sealed dispensers that dispense the following when pressed:

  • Anti-acne formula: 10% ultramicronized benzoyl peroxide – a powerful ingredient with proven antibacterial and anti-inflammatory efficacy. Thanks to its small molecule size, it penetrates deep into the epidermis.
  • Anti-aging formula: an active form of retinol (0.5–0.6%), anti-aging peptides, and hyaluronic acid – a powerful combination for combating wrinkles, pigmentation, and loss of firmness.

Why are the ingredients stored separately? Benzoyl peroxide and retinol are incompatible during storage: upon contact, they oxidize and lose their effectiveness. A double-sealed dispenser completely solves this problem—the active ingredients are mixed immediately before application.

Key ingredients and their actions

Component Action
Ultramicronized benzoyl peroxide (10%) Antibacterial, anti-inflammatory action; normalizes sebum secretion; Propionibacterium acnes destruction
Retinol (active form) Stimulates cell renewal, smooths wrinkles, lightens pigmentation
Anti-aging peptides Dermal regeneration, stimulates collagen synthesis, strengthens skin
Hyaluronic acid Deep hydration, maintains elasticity and smoothness of skin texture
Alpha-bisabolol Soothing, softening, antibacterial effect; Combating rosacea
White tea extract Antioxidant protection, toning, prolonging cell youth
Chrysin Combating pigmentation and evening out skin tone
NHS (N-hydroxysuccinimide) Reducing dark circles and age spots

General information

What results to expect

Jan Marini Age Intervention Duality cream delivers comprehensive results:

  • Reduction of inflammation and breakouts
  • Normalization of sebum production
  • Smoothing of fine and medium wrinkles
  • Lightening of age spots and post-acne marks
  • Evening of skin texture and tone
  • Increased elasticity and density
  • Improved hydration and barrier function

According to patient reviews, with regular use, minor inflammation subsides after the first application at night, and skin condition noticeably improves within a few weeks. This product consistently receives high marks from patients with age-related acne.

How to use

  1. Cleanse your face and wait until your skin is completely dry.
  2. Apply one pump of each pump.
  3. Quickly mix the two ingredients in your palm.
  4. Apply a thin layer to problem areas, avoiding the eye area.

Important instructions for use:

  • Introduce the product gradually: 1-2 times a week at night for the first 1-2 weeks.
  • If irritation does not occur, increase the frequency to 3 times a week, then, if necessary, to daily use.
  • Retinol and benzoyl peroxide increase photosensitivity. Be sure to use sunscreen with SPF 50 during the day.
  • Not recommended for use during pregnancy and breastfeeding. Breastfeeding
  • If severe dryness or flaking occurs, reduce the amount of product as recommended by your doctor.

It's best to consult your cosmetologist for detailed application recommendations.

When should you see a K+31 cosmetologist?

Duality Cream is an effective home care tool, but it is most effective when used as part of a comprehensive program designed by a specialist. Leading dermatologists and cosmetologists work in the K+31 cosmetology department, who:

  • Assess your skin's condition based on your individual needs.
  • Select the optimal retinol concentration (0.5%, 0.6%, or 0.9%).
  • Create a personalized care program.
  • If necessary, supplement your home care with hardware treatments, such as superficial peels and broadband light (BBL) to improve microrelief.

The K+31 Clinic uses only certified cosmetic products from renowned brands and provides a comprehensive approach, from diagnosis to solving aesthetic problems.

Jan Marini Age Intervention Duality Cream FAQ

What skin type is Age Intervention Duality suitable for?

The cream is suitable for all skin types: problematic, oily, combination, normal, and even dry. It is especially effective for those with a combination of acne and age-related changes.

Can Age Intervention Duality be used without a prescription from a cosmetologist?

The product contains active ingredients (retinol, benzoyl peroxide), which require careful integration into your skincare routine. A preliminary consultation with a dermatologist or cosmetologist is recommended to determine the optimal regimen.

Why does this cream consist of two parts?

Benzoyl peroxide and retinol are incompatible ingredients during long-term storage. A double-sealed dispenser prevents oxidation and maintains maximum potency until application.

Will my skin peel?

During the adaptation period, mild peeling and dryness are possible—this is a normal reaction to retinol. This is why the product is introduced gradually, starting with 1–2 times per week.

Can Age Intervention Duality be used in the summer?

Yes, provided that you always use sunscreen with SPF 50. Retinol increases skin's photosensitivity, so UV protection is essential year-round.

What is the volume of the product and how long does it last?

The volume is 28 ml (both components combined). When applied sparingly in a thin layer to problem areas, the package will last for 2-3 months.

How does Age Intervention Duality differ from regular retinol creams?

Unlike single-ingredient products, Duality simultaneously combats acne (benzoyl peroxide) and age-related changes (retinol + peptides), and its dual packaging ensures the stability of both active ingredients.

Where can I buy the original Jan Marini Age Intervention Duality?

The original product can be purchased from official distributors or recommended by a cosmetologist at the K+31 clinic, where only certified products are used.
