Peter Thomas Roth Mega Rich Intense Anti-Ageing Cellular Cream
Peter Thomas Roth Mega Rich Intense Anti-Ageing Cellular Cream is a high-performance moisturizer engineered to target the visible signs of aging while delivering deep, long-lasting hydration. This rich cellular cream is formulated with a potent peptide complex, specifically Acetyl Hexapeptide-8, which helps to smooth the appearance of fine lines and wrinkles. The texture is notably thick and luxurious, utilizing a blend of emollients like C12-15 Alkyl Benzoate and Glyceryl Stearate to create a protective moisture barrier. While it excels at revitalizing mature skin and restoring elasticity, the formula's density is a key characteristic of its 'mega rich' profile. It aims to leave the skin feeling firmer and more resilient, catering to those who prefer a heavy-duty cream for their nighttime or winter skincare routines. However, its complex ingredient list requires a closer look for those with specific pore-clogging concerns, as the richness comes from a variety of oils and extracts that provide intense nourishment at the potential cost of breathability for certain skin types.
Our Analysis
Our analysis classifies this product as having a HIGH comedogenic risk. The most significant concern is Algae extract, which carries a maximum rating of 5/5; its high iodide content can irritate the pore lining and trigger micro-comedones. The formula also contains Isocetyl stearate (4/5) and Oleic acid (4/5), both of which are known to be heavy and capable of disrupting the skin barrier or inducing blockages. While the cream offers beneficial peptides, the combination of these high-risk ingredients with secondary clogs like avocado oil and various fatty alcohols makes it highly likely to cause congestion in acne-prone individuals.
Skin Type Recommendations
This cream is best for very dry, mature skin types that require intense emolliency and aren't prone to acne. It is not recommended for oily, combination, or acne-prone skin due to the high concentration of pore-clogging ingredients. Sensitive individuals should also be cautious of potential irritation from the algae extract.
Flagged Ingredients
Rich in iodides which irritate the pore lining, triggering inflammation and micro-comedones.
Heavy ester that is difficult for the skin to excrete.
Disrupts skin barrier function and induces pore blockage.
A fatty alcohol (emollient) that is generally safe, but can be problematic for very sensitive individuals.
Rich and heavy oil; excellent for dry skin but can be too heavy for very oily skin types.
Pure Vitamin E is thick and sticky; safe in small amounts as an antioxidant, but potentially clogging in pure oil form.
Fractionated coconut oil; removed most clogging long-chain acids but can still affect some.
Waxy fatty alcohol; low risk but can add heaviness.
Fatty alcohol fraction of lanolin; safer than whole lanolin.
