Skin1 product guide
Choose C E Ferulic if your priority is a vitamin E antioxidant serum for normal-to-dry skin and visible lines. Choose Phloretin CF if uneven tone is your main concern and you prefer an oil-free serum for normal, combination or oily skin. Both checked 1 fl oz bottles cost $185, so the decision is about the formula.
C E Ferulic combines 15% vitamin C with 1% vitamin E. Phloretin CF combines 10% vitamin C with 2% phloretin. Both have 0.5% ferulic acid. Phloretin also lists denatured alcohol; the current C E Ferulic list does not. For someone avoiding that ingredient, C E Ferulic is the straightforward choice between these two.

The vitamin E option: 15% L-ascorbic acid, 1% vitamin E and 0.5% ferulic acid, with glycerin and sodium hyaluronate in the current formula.
Consider: No salicylic acid or phloretin is listed. Choose it for its vitamin E formula and normal-to-dry skin focus, rather than oil control.
Use: Apply 4–5 drops after morning cleansing to face, neck and chest; follow with the rest of your skincare and sunscreen.
The uneven-tone option for normal, combination and oily skin: 10% L-ascorbic acid, 2% phloretin and 0.5% ferulic acid in an oil-free liquid serum.
Consider: Denatured alcohol is third in the published list. It has no listed vitamin E or salicylic acid.
Use: In the morning, after cleansing and toning, apply 4–5 drops to dry face, neck and chest before other skincare. Follow with moisturizer as needed and sunscreen.

The names point to the main distinction. C E Ferulic supplies tocopherol, the vitamin E ingredient, alongside its higher stated vitamin C concentration. Phloretin CF replaces that emphasis with phloretin and a lower vitamin C percentage.
SkinCeuticals positions Phloretin CF around discoloration and tone evenness. C E Ferulic is the more natural starting point for its normal-to-dry skin positioning and visible lines. Decide which description fits the problem you are trying to address.
Phloretin CF has a short eight-ingredient list with denatured alcohol near the start. C E Ferulic has glycerin, panthenol and sodium hyaluronate, plus carnosine and dandelion-derived ingredients in the current version.
Neither displayed formula lists fragrance/parfum or salicylic acid. If oiliness and blemishes are the deciding issue, the three-serum guide includes Silymarin CF, which does contain salicylic acid.
At the verified one-time US prices, each costs $185 for 1 fl oz, or $185 per fl oz. Phloretin CF is not the cheaper choice simply because it has 10% rather than 15% vitamin C.
Use the retailer links in the price table for these exact liquid serums. Phloretin CF Gel is a separate product and is not the bottle compared here.
Apply your chosen serum after cleansing, before moisturizer and sunscreen. Phloretin’s directions specify 4–5 drops on dry skin; C E Ferulic also uses 4–5 drops across face, neck and chest.
When replacing one with the other, put the new serum in that same morning step. Buying both does not add a missing routine step.
