Source Naturals Skin Eternal Serum moisturizing serum, 1.7 fl oz — lightweight C‑Ester & DMAE hydrating formula

Source Naturals Skin Eternal Serum is a fast-absorbing moisturizing serum formulated with C-Ester, DMAE, lipoic acid, biotin and botanical extracts to help skin feel softer and replenished.

This lightweight serum blends targeted actives and calming botanicals in a non-greasy base to hydrate and smooth facial, neck and hand skin. Designed for daily use, the formula combines vitamins, amino derivatives and plant extracts so layers absorb quickly and leave a supple finish. Packaged in a 1.7 fluid ounce bottle from a trusted supplement and wellness brand, the serum is easy to include in morning and evening skincare routines.

How should I use Skin Eternal Serum in my daily routine?

Apply the serum to clean skin once or twice daily for best results. A little goes a long way: 1 to 4 drops are enough for the face, neck or the backs of hands, and it layers well under moisturizer or sunscreen.

• Shake well before use to blend ingredients.
• Dispense 1–4 drops onto fingertip, then gently massage into desired area.
• Use alone for a lightweight finish or under cream for added hydration.

What active ingredients are included and what do they do for skin appearance?

The serum features a combination of vitamin derivatives and supportive botanicals chosen for skin comfort and surface smoothing. C-Ester (a stable vitamin C form), lipoic acid and DMAE are included alongside biotin and chamomile extract to balance antioxidant support and calming benefits.

• C-Ester: stable vitamin C derivative for antioxidant support and tone evening.
• Lipoic acid: multifunctional antioxidant to help refresh skin surface.
• DMAE and biotin: supportive ingredients to promote a firmer feeling texture.
• Chamomile extract: botanical calming agent for sensitive-prone areas.

Will this serum work for my skin type and sensitive areas?

The formulation is lightweight and absorbs quickly, making it suitable for a range of skin types including normal, combination and many dry or sensitive skins. Because it contains active ingredients, patch-testing before first use is recommended if you have very reactive skin.

• Suitable for face, neck and hands where skin needs extra moisture.
• Non-greasy texture that layers under other products easily.
• Patch test recommended for highly reactive skin types.

Who is this for: Source Naturals Skin Eternal Serum is intended for anyone seeking a concentrated yet lightweight moisturizer that blends vitamin derivatives, DMAE and botanical extracts. It suits daily users who want a quick-absorbing product to smooth and hydrate facial and hand skin, people layering targeted serums under creams or sunscreen, and those who prefer a formula from a long-established U.S. manufacturer. Always follow usage directions and test new skincare products on a small area first if you have concerns about sensitivity.
