Does Medik8 Crystal Retinal contain parabens, sulfates or fragrance?
A straight yes or no for the ingredient groups people most often want to avoid, checked against this product's published formulation.
Free from parabens
Preservatives; the longer-chain ones (propyl, butyl) carry the endocrine questions.
Free from sulfates (sls / sles)
Strong cleansing agents that can strip a compromised barrier.
Free from silicones
Slip and occlusion; cyclic silicones (D4/D5/D6) are the environmentally restricted ones.
Free from fragrance / parfum
Undisclosed fragrance blends are the most common trigger for sensitised skin.
Free from essential oils
Naturally derived, but among the most frequently reported contact allergens.
Contains drying alcohol
Found: phenoxyethanol. Fine in small amounts for texture; high up the list it can dehydrate.
Free from formaldehyde releasers
Preservatives that slowly release formaldehyde.
Free from chemical uv filters of concern
Restricted or debated filters with endocrine or reef-persistence questions.
Is Medik8 Crystal Retinal non-comedogenic?
No ingredients in this formulation appear on Selenssa's common pore-clogger list, so it is unlikely to be the cause of congestion for most people. Comedogenicity is still individual — texture, occlusion and how much you use all play a part.
Is Medik8 Crystal Retinal safe for sensitive skin?
Generally a reasonable choice for sensitive skin.
- No fragrance or parfum in the list
- Contains a drying alcohol
- No ingredients flagged for irritation risk
Can you use Medik8 Crystal Retinal while pregnant?
This product contains retinal (retinaldehyde), which is usually on the list of ingredients people are advised to pause during pregnancy or breastfeeding. Selenssa is not medical advice — check with your midwife, GP or dermatologist before using it.
