Source Naturals Skin Eternal Serum 1.7 fl oz — lightweight moisturizing facial serum with C‑Ester & DMAE

This concentrated 1.7 fl oz serum combines water-loving and antioxidant-support ingredients to deliver a silky, replenishing layer that sinks in quickly. Designed for daily use on face, neck and hands, the formula blends stable vitamin C (C-Ester), DMAE and lipoic acid with vitamins A and D-3 plus chamomile extract to target dryness and improve skin feel without heavy residue. Manufactured in Scotts Valley, California, the product reflects Source Naturals' long history of nutritional and personal-care formulations introduced in 1982.

How will this serum fit into my morning and evening routine?

Apply the serum after cleansing and toning, and before heavier creams or sunscreen in the morning. In the evening it pairs well with nighttime moisturizers or oils to enhance overnight hydration and skin comfort. The lightweight texture makes layering simple for both AM and PM regimens.

• Use 1–4 drops per area as recommended; a little stretches far.
• Pat or massage gently into face, neck, and hands until absorbed.
• Follow with moisturizer or sunscreen depending on time of day.

What key ingredients are in Skin Eternal Serum and why are they included?

The formula centers on C-Ester (a stabilized vitamin C derivative), DMAE and lipoic acid to support skin texture and oxidative balance while biotin and vitamins A and D-3 complement skin nourishment. Chamomile flower extract adds gentle botanical support, and the serum’s base is designed for quick absorption without greasiness. These components were chosen to create a balanced, multi-functional serum suitable for layering.

• C-Ester: stabilized form of vitamin C for surface-level antioxidant support.
• DMAE: used for improving skin firmness and smooth application feel.
• Lipoic acid: a versatile antioxidant that mixes well with other actives.
• Biotin, vitamins A and D-3, chamomile: supportive nutrients and botanical extract.

How do I use the serum safely and get best results?

Shake the bottle well before each use to mix any settled ingredients. Start with 1–2 drops to assess how your skin responds, then increase up to 4 drops for fuller coverage; apply once or twice daily depending on tolerance. Always patch test a small area if you have sensitive skin and follow with sunscreen during daytime use.

• Shake well before dispensing.
• Apply 1–4 drops to clean, dry skin and massage gently.
• Patch test new routines and use sun protection during the day.
