Vichy Liftactiv Peptide-C Sunscreen SPF 30 Versus La Roche-Posay Anthelios Melt in Milk Sunscreen Lotion SPF 100 Detailed comparison of Vichy Liftactiv Peptide-C Sunscreen SPF 30 versus La Roche-Posay Anthelios Melt in Milk Sunscreen Lotion SPF 100. This chemical sunscreen covers most of the UV range, lighter on the deep UVA that drives aging.

Ingredients higher up in an ingredient list are typically present in a larger amount. Also known as Avobenzone, this ingredient is an oil-soluble used to absorb the full spectrum of UVA rays (peak 357 nm). It's one of the most effective UVA filters available but has a major caveat of photostability: avobenzone is susceptible to photodegradation. This means it can lose efficacy when exposed to sunlight without the help of a stabilizing agent. Studies show antioxidants (like vitamin E or vitamin C) and some UV filters (like octocrylene and Tinosorb S) can meaningfully improve its stability in a formulation. The maximum allowable concentration according to regulation is 3% in the US + Canada, and 5% in the EU, Australia, China, Korea, and ASEAN countries. It has a well-support safety profile: a comprehensive 2025 review found minimal toxicity with no evidence of carcinogenicity. Overall, avobenzone is a safe and regulated ingredient used in sunscreen for over 40 years. Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created. Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin. Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on). Dimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane. What it does: Dimethicone comes in different viscosities: Depending on the viscosity, dimethicone has different properties. Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity. This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient. Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy. Ethylhexyl Salicylate (also called Octisalate or Octyl Salicylate) is an oil-soluble organic UV filter that's been used in sunscreen since the 1950's. It absorbs UVB light in the 280-320 nm range with a peak absorbance around 306 nm. You'll often see it paired with other UV filters to boost overall SPF because octisalate is a fairly week filter on its own. The reason you'll see it so often is because it can help solubilize and stabilize the trickier filters like oxybenzone and avobenzone. Unlike these filters, octisalate has pretty good photostability and doesn't create skin-damaging free radicals when exposed to sunlight. The fatty-alcohol part of the molecule also gives it a light, emollient feel so it doubles as a nice texture enhancer. Usage levels vary around the world: Safety-wise, this ingredient has
