โ“ Frequently Asked Questions

Yes, this eye butter is considered safe for pregnancy and breastfeeding. It does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreens that are typically avoided during pregnancy. The formula relies on peptides, botanical extracts, and sunflower seed oil which are all pregnancy-safe ingredients. However, always consult with your healthcare provider if you have specific concerns.

No, this product is NOT fungal acne safe. It contains several ingredients that can feed malassezia yeast, including: oleic acid, stearic acid, palmitic acid, sunflower seed oil, sorbitan isostearate, arachidic acid, and cetearyl alcohol. If you have fungal acne or are prone to pityrosporum folliculitis, you should avoid this product and look for alternatives specifically formulated to be fungal acne safe.

Yes, this eye butter can be used alongside most active ingredients. Since it doesn't contain any strong actives itself (just peptides and botanical extracts), it pairs well with retinol, vitamin C, AHAs, and BHAs. When using with retinol, apply the eye butter after your retinol has absorbed to provide extra nourishment. With vitamin C, you can layer them in the same routine. The nourishing formula can actually help buffer potential irritation from active ingredients.

This eye butter works well for most skin types. It's particularly excellent for dry, dehydrated, combination, and sensitive skin. Despite its rich buttery texture, it absorbs quickly and is recommended by the brand even for oily skin types who typically avoid heavy eye creams. It's especially good for those prone to milia, as it doesn't clog the delicate eye area. However, those with fungal acne should avoid this product.

You'll notice immediate hydration and comfort after the first application. Improved skin texture and softness typically become apparent within 1-2 weeks of consistent use. For visible fine line reduction and anti-aging benefits from the peptides, expect to wait 4-6 weeks minimum, as peptides work in deeper skin layers where changes take time. Full benefits for elasticity and firmness become more noticeable after 8+ weeks of consistent daily use.

Apply the eye butter after cleansing, toning, and applying any serums, but before your face moisturizer. In the morning routine: Cleanser โ†’ Toner โ†’ Serum โ†’ Eye Butter โ†’ Moisturizer โ†’ Sunscreen. In the evening: Cleanser โ†’ Toner โ†’ Serum/Treatment โ†’ Eye Butter โ†’ Moisturizer. If using with the Klairs Fundamental Eye Awakening Gel, apply the gel first, then layer the butter on top for enhanced benefits.

This eye butter has a low comedogenic rating of approximately 1/5, meaning it has minimal pore-clogging potential. The main oil (sunflower seed oil) has a comedogenic index of 0. The brand specifically states it's suitable for those prone to milia, as the lightweight texture absorbs quickly without leaving heavy residue. However, individual reactions vary, so patch testing is always recommended if you're particularly acne-prone.

The product has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal effectiveness and safety. The 20g tube typically lasts 2-3 months with twice-daily use on the eye area alone. If you extend application to other areas like nasolabial folds or neck, it may last 4-6 weeks. Store in a cool, dry place away from direct sunlight to maintain product integrity.

โ˜…โ˜…โ˜…โ˜…โ˜†
4.3 out of 5

Verdict: The Dear Klairs Fundamental Nourishing Eye Butter is an excellent choice for those seeking a gentle, peptide-rich eye treatment without harsh actives. Its standout features are the quad-peptide complex (including Argireline and Copper Tripeptide-1), fast-absorbing buttery texture, and milia-safe formula. While it won't dramatically transform deep wrinkles or significantly brighten dark circles, it excels at prevention, hydration, and maintaining youthful elasticity. The fragrance-free, vegan formula makes it ideal for sensitive skin and pregnancy. Best suited for those in their 20s-40s focusing on prevention and early signs of aging. The only notable drawbacks are the small tube size and incompatibility with fungal acne-prone skin.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
