PUR Ceretin Boost Age Defying Retinol Serum 30ml
Description
Description
Retinol serum with 4x stronger Ceretin Complex, niacinamide, and ceramides
After decades of research, retinol remains the most proven active ingredient against skin aging. Clinical studies consistently show improvements in fine lines, pigmentation irregularities, skin texture, and firmness — no other cosmetic ingredient comes close to this track record. However, conventional retinol has one major drawback: irritation. Redness, dryness, and flaking cause many people to give up before seeing results.
PUR Ceretin Boost solves this problem with PUR’s own Ceretin Complex — an encapsulated retinol technology that releases the active ingredient in a controlled dose onto the skin. The new formula is also four times more potent than the original version, without sacrificing skin tolerance. Enhanced with niacinamide, ceramide AP, shea butter, and bisabolol, Ceretin Boost delivers the effects of a professional retinol treatment with the comfort of a nourishing cream.
Benefits
- Visibly reduces fine lines, wrinkles, and pigmentation irregularities
- 4x more powerful Ceretin Complex with encapsulated retinol
- Plumps the skin and restores visible firmness
- Niacinamide and ceramides support the skin barrier during retinol use
- Suitable for beginners thanks to controlled, dosed retinol release
Active Ingredients
Ceretin Complex (encapsulated retinol): PUR’s proprietary technology where retinol is contained in microcapsules, allowing it to be released gradually onto the skin instead of penetrating all at once. This prevents typical retinol irritation (redness, dryness, flaking) while fully maintaining its effects on cell renewal, collagen stimulation, and pigmentation reduction. The new formula delivers four times stronger effects than the original Ceretin Complex.
Niacinamide (vitamin B3): A broad-acting skincare active that specifically strengthens the skin barrier — crucial when using retinol. Niacinamide reduces the risk of irritation and dryness caused by retinol, improves skin tone evenness, and helps reduce pigmentation irregularities.
Ceramide AP & shea butter: Two lipid-replenishing actives that nourish and restore the skin barrier. The skin barrier is often more vulnerable during retinol use; ceramide AP replenishes natural fats between skin cells, while shea butter provides a rich nourishing layer that keeps skin supple. Together, they prevent dryness lines and flaking often left by other retinol formulas.
Iris Pallida Leaf Cell Extract: Plant stem cells from the blue iris, an ingredient linked in clinical research to improved skin firmness and evenness over the long term. Iris extract works synergistically with retinol to enhance visible results on wrinkles and skin tone.
Bacillus Ferment & lactic acid: A fermented active combination with mild exfoliating effects. Bacillus ferment supports natural skin repair, while lactic acid (a gentle AHA) refines the skin surface without being harsh. Together, they create a smoother base for optimal retinol penetration.
Bisabolol & vitamin E: Two soothing, antioxidant-rich ingredients that protect the skin from oxidative stress. Bisabolol (derived from chamomile) is one of the most calming natural ingredients and helps reduce any mild sensitivity during the first weeks of retinol use.
How to Use
- Thoroughly cleanse your face and apply toner or essence if desired
- Wait until the skin is completely dry — retinol on damp skin can increase irritation
- In the evening, apply two to three drops of Ceretin Boost to the face and neck, avoiding direct contact with the eye area
- Blend in with upward, tapping motions until the serum is absorbed, then follow with your night cream
- Always finish in the morning with broad-spectrum sun protection of at least SPF 30 — retinol increases sensitivity to UV light
Suitable For
- Mature skin with fine lines, wrinkles, or loss of firmness
- Skin with pigmentation spots, sun damage, or melasma
- Skin with uneven texture, enlarged pores, or dull appearance
- Beginners with retinol thanks to the dosed Ceretin Complex
- Those who have stopped previous retinol products due to irritation
Frequently Asked Questions
Am I suitable for retinol if I have never used an active serum before?
Yes, and Ceretin Boost is specifically developed to make starting retinol more accessible. Thanks to the encapsulated technology and the addition of niacinamide and ceramides, you get the effects of retinol with significantly less chance of irritation. Start slowly: use two to three times a week in the evening during the first week, observe your skin’s reaction, and gradually build up to daily use.
How long does it take to see results?
Initial results on skin texture and hydration are usually visible within two to four weeks. Reduction of fine lines and pigmentation spots requires six to twelve weeks of consistent use. For deeper wrinkles and substantial skin renewal, expect three to six months — as with all retinol effects, consistency is the key factor, not concentration.
Can I use retinol during pregnancy or breastfeeding?
No. Retinol and all vitamin A derivatives are generally not recommended during pregnancy and breastfeeding. For skincare during this phase, safer alternatives include peptides, niacinamide, and hyaluronic acid — always consult your gynecologist or skin therapist if in doubt.
Can I combine Ceretin Boost with vitamin C or acids?
Combination is possible but requires proper timing. The classic approach: vitamin C in the morning for antioxidant protection, Ceretin Boost in the evening for regeneration. Strong chemical exfoliants (glycolic acid, salicylic acid in high concentrations) should not be used in the same routine as retinol — alternate them day and night or week by week. With any combination, introduce one product at a time to properly monitor skin reactions.
How quickly does my skin get used to retinol?
Most users experience mild dryness, flaking, or slight tightness during the first two weeks — this is called the "retinization process" and indicates the active ingredient is working. By gradually increasing use (two to three times per week → every other day → daily) and intensive hydration, these effects remain minimal. After four to six weeks, the skin is usually fully accustomed to daily use.
