Luna Rain uses a powerful yet gentle 13% blend of 15 fruit and bark acids, including Glycolic, Lactic, and Salicylic acids, to exfoliate the skin. These natural acids work together to gently remove dead skin cells, promoting smoother texture, refined pores, and a more even skin tone, while still being kind to the skin. Additionally, marshmallow root, seaweed collagen, and other botanical actives provide soothing hydration, ensuring your skin stays calm and nourished throughout the resurfacing process.
Yes! Luna Rain is gentle enough for all skin types, including sensitive and acne-prone skin. The 13% blend of fruit and bark acids, along with marshmallow root, seaweed collagen, and other botanical actives, offers soothing hydration and effective exfoliation, making it perfect even for dry, oily, combination, blemish-prone, or sensitive skin.
Luna Rain stands out because it combines a potent 13% blend of 15 gentle acids, including glycolic, lactic, and salicylic acids, with soothing marshmallow root and seaweed collagen. Unlike many exfoliating serums that rely on synthetic exfoliators, Luna Rain uses natural fruit and bark acids that are more biocompatible with your skin barrier. Plus, other natural exfoliators often don't use a diverse enough range of acids, which is where Luna Rain excels, offering a comprehensive exfoliation while also addressing fine lines, irritation, and hydration—all in a gentle, milky, non-drying formula.
After cleansing and toning, apply a thin layer of Luna Rain to your face, avoiding the eye area. Since Luna Rain is a night treatment, it's best used in your evening skincare routine. For maximum results, if you're layering with other Earth Harbor serums, we suggest using Luna Rain as your first treatment to allow the acids to work effectively. Follow with your favorite moisturizer to lock in hydration and nourish your skin overnight. For daytime use, always apply sunscreen, as exfoliation can make your skin more sensitive to the sun. If you’re new to acid treatments, start by using Luna Rain 2-3 times a week and gradually increase usage as your skin adjusts.

Luna Rain gently exfoliates with a potent 13% blend of 15 acids, while soothing with marshmallow root, seaweed collagen, and other botanical actives. These ingredients work together to calm the skin, support hydration, and improve elasticity, helping to reduce the appearance of fine lines and wrinkles. The plant-based acids gently resurface the skin, while the nourishing actives promote a smoother, more youthful complexion.
Many users notice smoother, more radiant skin after just one use. With continued use, you’ll see a more even texture, reduced fine lines, a reduction in hyperpigmentation, more skin clarity, and enhanced glow thanks to Luna Rain’s exfoliating and nourishing ingredients.
Luna Rain is gentle enough for use every night, but for best results, we recommend starting with 2-3 times a week and increasing frequency as your skin builds tolerance. Its gentle yet powerful blend of acids and actives works to improve skin texture and radiance without causing irritation.
Yes! Luna Rain pairs well with most active ingredients like Vitamin C, peptides, and retinol alternatives. It can also be used with any Earth Harbor products, as our formulations are designed to complement each other. If using products outside of our line, avoid pairing Luna Rain with traditional retinol or other exfoliating treatments, as they may cause irritation when combined with the AHA/BHA blend. Always wear sunscreen during the day to protect your skin after exfoliating.

Amazing products!! I ❤️ how gentle the luna rain is, but it works so well on clearing up skin, and gentle exfoliating. I really appreciate how eco friendly the packaging is, and the great ingredients used in this. Thank you 😊.

Nightly Routine!
I’ve been using this for several months after receiving it the first time as a free mini gift. It’s helped with skin texture, redness, and moisture. It’s a daily for me!
