SkinCeuticals has added a cream to its P-TIOX range, which now includes the original P-TIOX Peptide Serum and the new P-TIOX Anti-Wrinkle Cream. Both are peptide-based skincare designed to target visible lines, so it is reasonable to wonder how they differ, which one to choose and whether there's any point using both.
Two Formats, Two Jobs in a Routine
The simplest way to think about it is by step. The P-TIOX Peptide Serum is a lightweight, hydrating serum that layers under other products. The P-TIOX Anti-Wrinkle Cream is a moisturiser, with what SkinCeuticals describes as a "micro-melting" cream texture that hydrates without feeling greasy.
So the serum sits earlier in your routine and the cream sits later. They are designed to work together, but each can also be used on its own.
What's in the Serum
The serum is built around a multi-peptide complex that combines a hexapeptide and a dipeptide, aimed at the appearance of expression lines on areas such as the forehead and around the eyes. It also contains 5% PHA, a gentle exfoliating acid, along with 5% niacinamide and laminaria (a brown seaweed) extract.
SkinCeuticals suggests five to six drops, morning and evening. In the morning it goes after a vitamin C serum and before sunscreen. In the evening, follow it with your moisturiser or corrective treatment.
What's in the Cream
The cream combines a tripeptide, a micropeptide and a plant-based complex SkinCeuticals calls Myrixin, which is concentrated in a flavonoid called myricetin. It also includes niacinamide, LHA (a type of hydroxy acid) and zinc PCA, with an emphasis on the look of deeper lines, visible pores and rough texture.
It is applied twice daily after your serum, pressed gently into the face, neck and around the eyes, then followed by sunscreen in the morning.
Choosing by Skin Type and Preference
If your skin is oily or combination, or you already have a moisturiser you love, the serum may be the easier fit. It adds a targeted step without changing the rest of your routine.
If your skin tends towards dry, or you would rather replace your current moisturiser than add another layer, the cream may make more sense. It can take the place of your usual moisturiser rather than sitting on top of it.
Both are listed as suitable for sensitive skin and are fragrance-free. That said, sensitive skin still benefits from introducing one new product at a time.
Do You Need Both?
Not necessarily. SkinCeuticals has designed the two to be used together, and some people like the combination of a serum and a matching moisturiser. Others get on perfectly well with one. It depends on your skin, your other products and how many steps you are realistically going to keep up.
If you decide to use both, start with one and add the second once you know how your skin responds. Since both contain exfoliating acids, take care when combining them with other exfoliating products, such as acid toners or strong scrubs, and ask for advice if your skin starts to feel tight or irritated.
Keeping Expectations Realistic
Peptide skincare works on the appearance of the skin's surface over weeks of consistent use. Results vary between people and depend on how regularly a product is used and how much is applied. These are topical skincare products, so they are best viewed as part of a long-term routine alongside daily sun protection.
Sunscreen matters as much as anything else here. UV exposure contributes to visible lines over time, so a broad-spectrum SPF50 or SPF50+ sunscreen is still the final morning step.
