SKIN TYPESGlycerin, shea butter, and betaine provide deep nourishment. Ideal everyday moisturizer for dry skin types.
Lightweight formula provides balanced hydration without feeling heavy. Great for maintaining healthy skin.

Frequently asked questions
FAQYes. The INKEY List confirms this product is safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. The formula uses only gentle peptides, glycerin, shea butter, and standard emollients that are considered safe for expectant and nursing mothers.
No. This product contains cetearyl alcohol, C12-15 alkyl benzoate, and shea butter which are flagged as potential triggers for fungal acne (Malassezia folliculitis). If you suffer from fungal acne, consider a fungal-safe moisturizer instead. These ingredients may feed the yeast responsible for fungal breakouts.
Yes. Peptides are compatible with all major actives. You can safely layer this moisturizer over retinol, vitamin C serums, AHAs, BHAs, and niacinamide. In fact, The INKEY List recommends pairing it with their Retinol Serum for enhanced anti-aging benefits. Apply your actives first, then follow with the Peptide Moisturizer to seal everything in.
This moisturizer is best suited for dry to normal skin types. It works well for combination skin in cooler weather. Oily skin types may find it too heavy, especially in warm and humid conditions. Sephora lists it as suitable for Normal, Dry, Combination, and Oily skin, but user reviews suggest it performs best on drier skin types.
Immediate hydration and softness can be felt from the first application. According to The INKEY List, skin cell turnover takes up to 6 weeks, so visible improvements in fine lines, firmness, and skin tone should be expected within 4 to 6 weeks of consistent daily use (morning and evening). Be patient and consistent for best results.
Apply as Step 5 in your routine: after cleansing, toner, serums/treatments, and eye cream. In the morning, follow with SPF as your final step. The brand recommends layering Hyaluronic Acid Serum underneath for extra hydration. For nighttime, you can follow with a facial oil to lock in all the moisture.
This product has a low comedogenic rating of 1 out of 5. The INKEY List states it is formulated without ingredients known to clog pores. It is oil-free and silicone-free. However, individual skin may react differently — if you are highly acne-prone, always patch test first. Note: cetearyl alcohol (comedogenic rating 2) is present but at low levels.
The Period After Opening (PAO) is 12 months. Once opened, use within one year for best efficacy. The tube packaging helps protect the formula from air and light exposure, extending its stability. Store in a cool, dry place away from direct sunlight. With twice-daily use of a pea-sized amount, a 50ml tube typically lasts 2 to 3 months.
Verdict: The INKEY List Peptide Moisturizer is an excellent budget-friendly entry point into peptide skincare. At just $15.99 for 50ml, it offers a clean, fragrance-free formula with two peptide actives at their recommended concentrations. It excels as a daily hydrator for dry to normal skin and is one of the best pregnancy-safe anti-aging moisturizers at this price point. However, the relatively simple formula means it works best as a supporting player alongside stronger treatments like retinol or vitamin C serums, rather than a standalone anti-aging solution. If you want an affordable, gentle peptide cream that does the basics well — this is a smart choice.

Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
