Will lip filler turn this area above the lip into actual lip from the side profile? (Photos)

From your description and photos, what you are noticing is related to natural lip anatomy. The upper lip has a transition zone where the pink of the lip (vermillion) meets the surrounding skin. In some people, this border is more tucked in when viewed from the side, which can make the lip appear less projected in profile even if it looks full from the front.

Filler can help in certain ways:

By carefully placing filler along the vermillion border and body of the upper lip, projection from the side can be improved so the lip appears more visible.

Techniques such as vermillion border definition or small amounts of filler in the upper lip body (rather than just a Russian lift) are commonly used for this goal.

The “Russian lip” technique focuses more on vertical lift and a heart-shaped appearance, while cross-hatching or micro-droplet techniques may give more subtle, natural projection.

Limitations to consider:

Some aspects are simply anatomic, meaning the skin above the lip will not fully “become lip” no matter how much filler is placed.

Overfilling for projection can look unnatural or distort the balance of the lips.

A conservative, precise approach is best to enhance profile while keeping natural proportion.

In summary, filler can help make the lip more visible from the side, but results will depend on your natural anatomy. The area you’re pointing to is indeed skin transitioning into the vermillion, not “missing lip,” and enhancement should focus on subtle projection rather than trying to completely change that anatomy.

The area you marked is the cutaneous upper lip (white lip) and vermilion border. It’s normal that it looks like skin from the side—filler can’t turn skin into red lip.
What filler can do: add 1–2 mm of projection and eversion by placing small amounts in the vermillion body (sub-mucosal), which makes the red lip more visible from profile.
What to avoid: heavy border/white-lip injections → shelf/“ducky” look and migration.
Best approach: conservative 0.3–0.6 mL first session, micro-aliquots to the central and lateral vermilion for eversion, minimal border work; reassess in 2–4 weeks.
Don’t chase a named technique (“Russian,” cross-hatch). Ask for sub-mucosal filler to increase eversion/projection, not vertical height.
Adjuncts: a small lip flip (4–10 units botulinum toxin) can increase show ~1–2 mm; consider dental/ortho review if teeth/jaw are retrusive and lips lack support.
After your chemical peel: inject only once skin is fully healed—~1–2 weeks after superficial peels, 4–6 weeks after medium/deep.
Safety notes: history of cold sores → prophylaxis; avoid treatment with active irritation; expect swelling 48–72h.
Bottom line: Filler can modestly improve side-profile visibility by everting the red lip, but it won’t convert the skin above the border into lip. Conservative, eversion-focused placement ± a lip flip is the right ask.
